Need to find a PCM or ECM.

Powertrain Control Module In air cleaner box.

Where is the computer located on a 2001 chevy impala

Hello -

If you are talking about the PCM, Power train Control Module it is located on the left Side Of Engine Compartment, Inside Air Filter Box.

I am trying to find someone who can tell me the location of the computer on a 2001 Chevy Impala 3.4 L and possible provide a picture. Thanks

Inside your air filter box.

Where is the ECU on a 2001 chevy impala 3.8 L and how do you replace it?

The PCM is in the aircleaner box

Excuse my ignorance; but is the PCM and ECU the same thing and is it difficult to replace?

Thanks

Its the same thing-disconnect the negative battery cable then find it and unplug the wiring connectors-Bear in mind that you might have to go thru a computer relearning process after replacement due to battery disconnection.
