I am attempting to replace my PCM/ECM/ECU myself and I am having difficulty with the location of the module. Any idea where I can find it? I can supply the VIN if that helps.

Hi,

The PCM is located on the air filter housing. See pic 1.

The remaining pictures are for the removal and replacement of the component. Note that this needs to be programmed for your vehicle. It will require a scan tool with the proper software to do this.

Let me know if this helps or if you have other questions.

Take care,

Joe
