Hi all. I have a 2001 Tek that's driving me crazy with a persistant P0405 code. I've narrowed it down to it not getting the 5V reference. If the harness is fine could it be the PCM? Is there any way to test the PCM? Thanks in advance for any help.

read the Solutions section of this link which explains what to do when no 5v is found. The PCM is the last item and unless you have a TechII or similar advanced scanner you cant test them.
