What will a bad PCM cause?
Bad PCM Causes
Engine performance issues
.
Engine misfiring or stalling and overall poor

- Your car stutters when starting, requires multiple attempts, or won't start at all.
- Stuttering or stalling during idling.
How much is a PCM for a Dodge Charger?
The average cost for a Powertrain Control Module Replacement is
between $852 and $868

Can you fix a PCM?
PCMs are
not rebuilt
in the same way that alternators and water pumps because there are no mechanical parts that wear out. Remanufacturing in this case usually means testing the computer, isolating and repairing any faults that may be found, then retesting the computer to make sure everything works correctly.
Is a PCM and ECM the same thing?
