I have a 2007 Chrysler 300 6 cylinder auto with the engine light on (not flashing). When I click on the ignition quickly on and off three times the odometer goes from showing my mileage to the number 1004. What does this indicate?

Can you tell me what a P code of 1004 means?

How do i reset the check engine light for my 2007 chevy impala???

The code is for “short runner valve control performance”. According to Alldata, there are several steps that we would need to go through to determine the actual problem. It could be a wiring problem or even a faulty Transmission Control Module (TCM). I would recommend a complete electrical diagnostic test.

The check engine light is on because it is storing a code or codes. We would need to hook up a scanner that would read the codes and then clear the codes with the scanner. Any AAMCO Center would be glad to do that at no cost to you. But, unless the source of the codes is repaired or replaced, the check engine light will come back on.

Had PO100 Replaced and idle arm throttle plus ECM replaced. Car driving just fine all at once it died, not it bucks, jerks, stalls and drives about 20 miles an hour. It slowly builds up speed. I just bought it and am a senior. I am at my wits end. What next can the mechanic look for. Replaced the code parts? I have a beautiful infinity 2001 i30 smd that is just pretty.

Yes, I have a code of P0172 & P0175, can you tell me what that means and how much will it cost to get fix, thank you.

The code is an important factor in diagnosing the problem but is not the only factor. The code at a general level means the same for all brands of vehicles, in your case the code is for a rich fuel mixture being probably detected in the exhaust system. However each manufacturer has more specific information based on the brand,car model,engine etc. that can be used to narrow the cause.
St. Louis AAMCO is offering to check your check engine light for free.
This will allow for an accurate estimate on what it will cost to fix your car’s problem. A coupon is attached for your use. Please call the closest store to you to set up an appointment.
Thank you and let us know if we can be of more help.

The P0100 code indicates a problem with the mass air flow circuit and your car’s symptoms are consistent with that error. It appears the car is having some trouble correctly determining the amount of air coming into the engine and making bad adjustments.
An AAMCO center would need some shop time to determine what is failing. This could take 30 minutes – 2 hours depending on how “buried” the problem is.
Please call the store nearest you and set up a time to leave your car for diagnostic time. The store will then be able to give you a more precise estimate of what it will cost to repair your car.
