2004 Chrysler Pacifica check engine light came on. Ran codes. Replaced erg valve and oxygen sensor. Can't clear codes and nothing new comes up

Clear codes by hooking up a scanner, and go through the "clear codes" sequence. It will erase all stored codes. If it doesn't, you have a problem with the ECM/PCM (engine computer), or the data link connector.

I have a 2004 Chrysler pacifica that would not start. We've had the battery tested and changed the starter. We've checked that there is power getting to the starter as well as the solenoid. We've also...

I have a 2007 chrysler Pacifica and it had the same problem. It would crank over but not start. Took some time to figure out but in the end the asd control wire that runs from the fuse box to the PCM was corroded in half about 5 inches from the fuse box. It would show 9 volts at the PCM but no continuity.

Location of pcm on 2005 pacifica?

I have a 2004 Pacifica and mine is on the drivers side front, underneath between the bumper and the wheel splash guard. You will need to remove the splash guard ti access the PCM. Not very hard at all. Replacement time for a handy DIYer: about 1/2 hour. Good luck!!
