Location of Engine Control Module for 2001 Pontiac Aztek

A number of engine related problems (non-fatal) have been ongoing for awhile. A mechanic said I should have the engine control module replaced. I have the module but where does it go? By the way, the ECM is not the same as the BCM.

    I found the ECM on the driver's side of the engine compartment underneath the Coolant Overflow Reservoir in a large black plastic box.



    Thanks for the help.

Transmission will not engage into any gear


Most likely your transmission has failed and needs to be rebuilt but please read more about the problem below.

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms

How do i reset service light on 2001 pontiac aztek?


Before you re-set it, take the car to AutoZone or other similar store to read the code. That way, you know why the service light came on.
Then AutoZone can re-set it for you (all free)!

== or ==

Disconnect the negative cable from the battery for 10 minutes, or more.
When you re-connect the battery cable, the service light will have benn reset. But it will turn back on eventually.

Hope this helps!
