I have an error message of missing voltage to MAF sensor. Where is the computer control module physically located. Where can I find a wiring diagram to see if there are any components between the ECM and MAF.

Hello, for the maf sensor, the pink wire is voltage goes hot when you turn on the key. The black wire with white tracer is ground. The yellow wire is the signal, goes to the pcm.

The autozone site has wiring diagrams for your vehicle, click on (vehicle repair guides) and follow the links.

I went through all of AutoZones documentation and found ZERO as far as wiring diagram or location of the Electronic Control Module or Electronic Control Computer on the 2002 Monte Carlo. I can not figure out whether it is under the dash by the steering column, or mounted (hidden) somewhere inside the engine compartment.

About the fifth line down for maf sensor wiring. I don't have a location for the pcm.
