2001 Mopar A604.Does it need pinion factor after PCM Change?

  1. Please fill out the following to ask a question.

    MAKE: Chrysler
    MODEL: Voyager
    YEAR: 2001
    MILES: 150,000
    ENGINE: 3.3
    DESCRIBE ISSUE....just picked up project, wouldn't run, found melted injector wiring and replaced with new harness but also needed new (used from yard) PCM. Runs great but even though the CEL is off, the scan shows that it is on but with no codes. First time I scanned after repairs it did show P0700 and P0720. I plan to throw an output speed sensor in it after checking for debris on old one, but before I do that, any chance the yard PCM needs pinion factor procedure?
     
  2. i would do it also i would relearn the CVI values
     
  3. Back to this, I thought CVI was strictly a TCM function? Why would swapping PCM affect that? Thanks,

    MT
     
  4. Is there a separate TCM on this vehicle? When TCMs came along, and soon got married to ECMs, they called that one assembly a... PCM (Trans Control Module + Engine Control Module = Powertrain Control Module)
     
  5. Yes, this has a separate TCM,

  6. i just recomend it as a precausion
