'02 Saturn Vue (V6/AWD/5 Spd AT). Scanned ECM, TCM, BCM, SDM & EPS for codes. One code found U1096 with Service Wrench light illuminated (Lost communication with IPC). IPC Connector resistance to ground (B4) is less than 1 ohm. IPC Connector voltage (B2) is 12.3 V. IPC functions as it should (Both while running and KOEO bulb check). Anyone seen this before?

My car has 230000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
You might have a problem with fretting corrosion in the connectors of the modules of the vehicle. There is a technical bulletin out for your Saturn VUE: 09-06-03-004D, dated December 2010 for corrosion in the small connector pins of the modules throughout the vehicle. The fix for this is to disconnect the battery. Then disconnect each module, including the ECM, TCM, BCM, SDM, EPS, and any other modules having issues then apply a thin coat of dielectric lube to the connector seals and each pin and socket. Once all are done and securely reconnected, reconnect the battery and retest systems. Clear any codes and road test to relearn the idle. If you need assistance with this, consider YourMechanic, as a certified technician can further diagnose the trouble codes and help you fix this accordingly.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The most common reasons a Saturn Vue has a check engine light are an emissions system component, a sensor, or a catalytic converter.
The Check Engine Light location and color will vary by vehicle, but in most cases it is a dashboard warning light that is yellow and shaped like an engine.
A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it`s in good condition. If you have a tank of bad gas in the car, your check engine light may come on.
Connecting to an OBD-II Port

You plug an OBD-II scanner tool into it and, in most cases, out pops a code that tells you what the problem is. The scanner also allows you to clear the vehicle`s internal code, which is what triggered the check-engine light. Do that, and the warning light will turn off.

The simplest way to describe the difference is that the Service Engine light informs us of upcoming expected maintenance. On the other hand, the Check Engine light informs you of an unexpected problem occurring in your engine or exhaust system.
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
These problems can range from faults within the electrical system, the engine, fluid levels or to problems within the car`s emissions system. The problem can even be as simple as forgetting to tighten your gas cap – in fact, this is the most common reason why check engine lights appear in the first place.
Diagnostic Trouble Codes, also known as engine fault codes, are five-digit codes that identify a particular problem in the car. These codes are displayed on the scanning tool when it`s connected to the OBD system. The five-digit DTC includes one letter usually followed by four numbers (e.g. P1234).
There are thousands of possible diagnostic codes possible, some that are specific to a manufacturer or particular vehicle, and many that are generic across all vehicles.
The most common reasons a Saturn Vue won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Can you drive a car with the engine light on? It`s okay to drive for a few miles, but be sure to schedule an inspection of the engine as soon as possible. If the check engine light comes on while you`re driving, don`t panic! Pay attention and see if the car is driving any differently than normal.
This is a sign you should stop driving and have your car looked at by a mechanic as soon as possible. Use your best judgment on whether to call a tow truck or drive yourself to a nearby repair shop. Is the light flashing? In many vehicles, there are two types of check engine lights—a solid light and a flashing light.
You can judge how serious an issue is by looking at the warning light. The check engine light can show up in two ways: Solid yellow/amber light: Indicates a less urgent issue. Flashing light or red: Indicates a severe problem that needs immediate attention.
All the problems that could trigger a check engine light are serious. If the check engine light comes on, it`s one dashboard light you should not ignore. Whether for a week, a month, or a year, if you ignore the check engine light, it puts your vehicle, and by extension, your personal safety at risk.

hey good day. im joey from the philippines. can you help me out. i would really an opinion about the problem in my car. my honda c
ANSWER : Hi Joey. Unfortunately, it’s hard for us to provide you the correct diagnosis of your issue for two reasons. First, we don’t offer services or repairs in your country, so it’s impossible for one of us to come to your location and inspect your car. Second, without knowing maintenance details, it’s hard to tell you what might be causing the noise. In some cases, it can be due to loose cylinder head hardware; so it may be that the mechanic is correct. I wish we could help more, but that’s really all the advice we can offer. Good luck to you.

hi i really need help with my axle cv join keep breaking
ANSWER : If the suspension has been altered and lowered, then you may be putting the drive axle in a bind. If the axle is put out of alignment and you make turns that put a bind in another direction it takes a toll on the axle joint which can only take so much. The right axle goes bad first since this is the drive axle that gets the most torque from the transmission. I would suggest the same as the dealer and put the suspension back to normal height and replace any worn components like the wheel bearing or axle. I’d suggest you get the car looked at by a certified technician who can inspect your suspension system. They can perform the necessary checks to assess the condition of your suspension and make any repairs or adjustments that are necessary.

Suddenly a whole lots of problems have occurred!!! Help!
ANSWER : My first thought is you have moisture inside your distributor cap. This is a very common issue with older vehicles. I suspect all these issues are caused by a single issue. Since it is overheating, I would certainly be checking your cooling system. I wouldn’t expect it to blow a head gasket, but your symptoms definitely fit. It could also be clogged carburetor jets.

With an overheating car, I would begin by determining which cylinder are misfiring. If cylinders are misfiring on only one head, I would suspect you have a head gasket failure. Whatever is overheating needs to be addressed. It is very difficult to diagnose a car when it is overheating.

Another possibility is the roll pin holding the gear on the distributor has sheared. This can cause overheating and all of your symptoms. I think I would begin by checking your timing. If it is way off, I would suspect this. While your there, inspect the distributor cap for moisture.

To summarize:

Check timing
Check for moisture
Check distributor gear
Check for head gasket failure
Clean carburetor jets
If none of this applies, diagnose your overheating issue.

If you should need further assistance, have a certified technician, like one from YourMechanic, diagnose your misfire firsthand for an accurate repair.

Good luck!

Please help me figure out where my PCV valve and PCV Hose is!!!
ANSWER : Hi there. The PCV valve is located on bank 1; the valve cover closest to the cabin. It is usually found under the intake plenum towards the passenger side of the vehicle. The hose will be attached; or loose. Please understand that a code retrieval and an internet search is not a proper diagnosis as there are several other possibilities that can cause the code to set. Some of the possible causes could be spark plugs, ignition coils, intake manifold leaks, intake plenum leaks, vacuum hose leaks, failing airflow meter, failing O2 sensors, exhaust manifold leaks, low fuel pressure, failing ECU, faulty wiring harness, failing injectors, etc… As you can see, the list of possibilities runs on and on. This is where the expertise and experience of a qualified technician with the proper diagnostic tools and procedures becomes invaluable. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts and determine the exact cause of the code. Your Mechanic has several available technicians that can assist you with a check engine light inspection.

My car turns on then shakes then it won’t turn on can you please help me out.
ANSWER : The good news is your problem is not "intermittent". That is, the problem will be readily apparent once the mechanic checks for fuel and spark. Problems that "come and go" are the ones that you don’t want to have. As far as the cause, it could be as simple as the coolant temperature sensor not reporting the "cold" status of the engine to the PCM (engine computer) and thus not enough fuel is being supplied to the fuel injectors (on first start) or you could have a bad fuel pump. There are also cam and crankshaft sensors that sometimes stop working. Inasmuch as there are so many other possibilities, your best bet by far is to simply request a no start diagnostic and the certified Mechanic will come out, probably check the fuel pump initially at key on, and then if the problem is not found there, just simply go through the diagnostic "decision tree" until the fault is found. If any diagnostic trouble codes have set, obviously that will shorten the diagnostic and so the Mechanic will see if your check engine light is on or if codes are stored in the engine computer.

i need your help my wolkswagen 2005 doesnt want to lock 2 doors… i’m not sure if it’s a fuse problem.. when i press the lock but
ANSWER : Hi there:

If the driver side doors are the only ones that unlock when you press the power lock button, then it’s more than likely that you have a damaged main power lock control module or electrical relay to the passenger side doors that’s causing this issue. However, to be certain that you get the right repairs completed on your Volkswagen, you might want to have a professional mechanic complete a power door locks are not working inspection first.

I’m chasing compression and trying to eliminate ticking. Can you help me adjust my valves? EFI SBF roller block
ANSWER : Hello. I would need to know more about the engine like what types of parts are being used. It simply sounds like the lifters were not bled off prior to setting the lash. If this was not done then that needs to be done prior to doing anything else. If it has been done then you may have some faulty lifters.
