Q
car year: 1997

car model: 328is

My BMW has failing emission check and that i have two codes. are you able to tell ME what those codes mean and also the half to repair it? P1423 and P1421.

A
These 2 codes area unit for the Secondary Air System, bank-1 and bank-2. Bank one is cylinders one through three and bank-2 is cylinders four through vi. These codes area unit indicating that the secondary air system isn’t functioning properly.

The secondary air system pumps contemporary air into the exhaust ports throughout cold engine start-up. This provides contemporary chemical element to help within the complete burning of the combustion mixture throughout the cold start-up amount, once the mixture is richer and isn’t burning expeditiously.

Commonly, the check valve at the manifold can fail (stick open) and this can permit exhaust gasses to enter the pump once it’s not running. this can destroy the pump. the standard repair involves substitution the pump and also the check valve (and the seal for the check valve). Of course, there area unit alternative areas inside the secondary air system that might be guilty. For additional data and elaborate diagnostic steps, please see the Summer 2008 issue of our quick Times account (below).

Q
I have a 1999 BMW 323i and also the scan code unbroken developing p1188/1189 and p0170 and p0173 . What area unit these codes and the way do I correct the the problem?

A
The P1188 and P1189 codes area unit for “fuel control” for each banks one and a pair of (cylinders 1-2 and 4-6, respectively). The P0170 Associate in Nursing P0173 area unit for “fuel trim”, again, for each banks one and a pair of.

With these codes, i might 1st search for vacuum leaks within the intake system. examine the rubber boots going from the MAF (Mass Air Flow sensor) to the throttle body, particularly the little leg that connects to the idle management valve, down by the throttle body. in addition, examine all vacuum and air handling hoses. Another common vacuum leak supply is that the housing ventilation. See the link below for extra data on the housing ventilation.

If you can’t realize any obvious vacuum leaks, you’ll have the system “smoke tested”. This injects a smoke into the intake and any leaks can permit the smoke to return out.

Do not forget regular vehicle maintenance and replacement of ignition

In several people’s minds, maintenance is nothing over replacement the 3 filters, oil and different consumables. In fact, throughout operation of the vehicle, several components ar in constant wear and tear, routine maintenance, scrutiny vary so much restricted to a few filters, oil, brakes, spark plugs, etc., plenty of places don’t listen if the standard scrutiny, maintenance, Associate in Nursingd aforesaid unsure once an sudden failure happens. Here ar a couple of components within the routine maintenance is usually neglected.

Ignition

many folks understand that the spark plugs ought to be modified often, however it ignores the upkeep of the mechanism to different components of the mechanism is one amongst them. once the engine is running, the ignition line usually have tens of thousands of volts of high voltage periodic current, as a result of it work long hours in hot, dusty, vibration setting, aging inevitably occur even broken. Therefore, it and therefore the electrical device, even as the requirement for frequent replacement of consumables.

Aging and broken ignition ignition energy can greatly scale back the engine fuel consumption rises, power down off the hearth will cause serious, and this can be a fatal failure for the engine with a converter is bothered. in keeping with the expertise of foreign countries, although there’s no fault, every with twenty thousand kilometers round the mechanism is additionally set to get replaced. several domestic automobile house owners usually need to wait till reminded to visualize the mechanism of the engine cannot be started even seem unstable operation failure, however during this case, attributable to the potential harm to the mechanism parts and waste fuel and decline the engine caused so much on the far side the its own price. additionally, the mechanism cap, distributor rotor, ignition coils, spark plugs and different parts ought to even be within the routine maintenance, scrutiny vary.

Brake disc

Brake disc and brake shoes ar a combine of friction, wear and tear of constraint, brake disc there’ll be some wear and tear, the explanation is incredibly easy and obvious, however many folks solely listen once the upkeep vehicle replacement Shoe , however usually overlook the replacement brake disc. the results of excessive disc wear could be a terribly serious, 1st of all, because of the reduced surface roughness, that the particular contact space becomes little, leading to light braking force

additionally, the worn brake disc heat capability decreases once the temperature rises in continuous braking quickly, additional liable to heat recession. All of that ar terribly dangerous driving. Some fix-it shop to severe decline the brake disc shaping machine, surface treatment, ordinarily referred to as “CD”, so the surface is sleek, however the disc becomes agent, brake thermal recession are going to be additional severe, additionally, high-temperature tempering causes the disc made within the method, and more reduces the mechanical strength. Generally, when the replacement of the constraint two to three times, the brake disc ought to get replaced. don’t feel unhealthy that a couple of hundred greenbacks, after all, human life is invaluable.

Generator bearings

currently several skilled worker was dubbed “stevedore”, which means just for components, not repairs. In fact, a number of the components as long as needed maintenance will greatly extend its life, the generator is one amongst them. Some years agone, a generator within the automobile fairly expensive parts, when Hou, a group of maintenance on the generator system, like time lubrication, replacement of bearings, adjust, replace carbon brushes, change the bit within the car’s maintenance necessities purpose gap so on, now, with the lower element costs, and routine maintenance of the generator has bit by bit been neglected. In fact, if you sign up accordance with the higher than provisions, the replacement of bearings, a minimum of prolong the lifetime of the generator is over doubled. In general, once the vehicle is traveling 6-80000 metric linear unit, the generator ought to be overhauled, additionally, water pump, steering system pump, air con mechanical device bearings ought to be checked often.

with the exception of some of necessary automotive electrical connectors with gold contacts, most of the remaining fittings ar created ​​of copper – Zn alloy, underneath traditional circumstances, its responsibility is bonded, however if the automobile could be a long-standing in warm temperature, high humidness , jolty run setting, it’s doable to supply these joints loose, corroded, poor contact and different failures. Therefore, throughout routine maintenance, ought to specialize in joint examination board pc, sensors, nozzles and different parts, if found to possess loose, unsound development will handle it with petroleum jelly, or replaced with new plugs.

Not In Good (Insurance) Company

(I work on the front desk at a repair shop. A client calls us back; they called earlier and spoke with someone else.)

Client: “I need you to tell me who my insurance is.”

Me: “…Pardon?”

Client: “I called before and you told me that I needed to find out who insured my car, so tell me who insures my car!”

Me: “Er, sorry, I wouldn’t know that. You need to know who your insurance is with.”

Client: “Well, I don’t know who my insurance is! Find out for me!”

Me: “I can’t do that. There’s more than two dozen insurance companies in the immediate area alone. Do you have any documents about your insurance? An insurance policy? An invoice?”

Client: “This is bullshit! I pay $1000 a month to be insured, and you don’t even know who it is?”

Me: “Sorry, sir, but we aren’t your insurance company. We fix cars. We don’t know who your insurance company is.”

Client: “WHY NOT?!”

Me: “Because we aren’t your insurance company, we haven’t ensured your car, and you have never dealt with us before. There is no way for us to know where your car is insured.”

Client: “When I bought this car, I spent a lot of money on getting this protection pack and I was promised [Insurance Company]‘s extended protection and—”

Me: “Excuse me—”

Client: “I’m not finished!”

(Cue a five minute long rant about how he spent so much money on his car, during which he mentions the insurance company’s name no less than four times.)

Me: “Excuse me, sir. But did you say that you have [Insurance Company]‘s protection?

Client: “YES!”

Me: “So, you mean [Insurance Company] is your insurance company?”

Client: “How should I know?!”

Me: “Okay, well, if you have [Insurance Company]‘s cover, then that is your insurance company.”

Client: “God, was that so f***ing hard?!”

The car suddenly stalled terrible it is important to identify the cause

Remember that period of time just to drive it? Remember it has repeatedly flameout? Remember the oil from the place it? Remember the clutch is always fast and flame lift it? Here follow me look at the car is turned off in the end is how it happened …… Honda HDS HIM Diagnostic Tool With Double Board

Car flameout reasons:

1, the automatic transmission models will not easily appear flameout phenomenon, and models due to manual driving level is not high, may often stall phenomenon. But do not rule out the automatic transmission car flameout phenomenon does not occur, mainly due to the use of the fuel poor (many gas stations in order to reap huge profits selling impure oil) lead to engine deposits and stall. Honda HDS HIM Diagnostic Tool With Double Board

2 In addition, the reason for stalling the new car (automatic transmission) occurs mainly caused by driving skilled enough, another possibility is that the car engine or the oil problem, but for a new car, the possibility of a problem than the engine itself is small, because the passage of most of the problems.

3, the last for the old models, the flame is not enough because in addition to driving skill, but it is not up to the quality of the oil using the engine flameout set of carbon as a result.

Automatic transmission car flameout troubleshooting methods:

Usually pay attention to places: For automatic transmission vehicles stalling phenomenon is caused by the fuel or the use of poor quality. First, the formal larger stations plus high-grade oil, for example, using 95 gasoline, although the price a lot more expensive, but you can protect your car longer life and the exercise of the power of good. But some owners freeloaders 92 plus oil, although the price a little lower, but problems may occur in the future. The second is to pass a large gas station!

Practice: left hand grasp the steering wheel to stabilize the direction (because there is no help, so be sure to firmly stabilize), right foot hard on the brakes to reduce the speed as much as possible, then quickly hit N AT stall speed, (note: the road to re-fight fire must be in the N range, can not be a D / R / P and other files, otherwise, the car or beat the fire, or the car will damage the gearbox), and then turn the key back a grid, and then re-ignition, then aT gear bit restored to normal driving D file.

Manual car flameout troubleshooting methods:

1, for the novice, halfway flame is not a new topic, the main approach to rapid run-in after exclusion improve their driving skills.

2, the use of high-standard quality of qualified fuel.

3, a thorough cleaning of the oil line will include fuel injectors, throttle, fuel tank and so on. There may be you add the oil quality, but off, plastic fat too much, the oil passage blocked, the attack caused by poor oil.Honda HDS HIM Diagnostic Tool With Double Board

4, the cause of the failure to turn off idling vehicles under mainly due to too much dust in the air, the engine is running at idle speed motor with the throttle valve seat at the deposition has many dirt, when excessive accumulation of dirt, the engine will be idling too low, idle stability is poor, idling flameout occurs when traveling. To solve this problem is simple: just wash idle speed motor can be.

5, oil is smooth, it can easily lead halfway flameout.

6, long-term car park is not used. In fact, should not be parked for a long time. If parked a long time, before re-use should do a thorough maintenance, oil changes, filter, etc., and, where appropriate check fuel circuit. Your vehicle may cause long-term parking is because lubrication or circuit problem.
