Before replacing your PCM, always perform a thorough inspection of your vehicle’s battery, terminals, and primary ground wires. A weak battery or a corroded ground connection can cause voltage drops that mimic PCM failure symptoms. Ensuring the electrical system is healthy is a crucial first step in any electronic diagnosis and can sometimes save you from an unnecessary replacement.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling, stuttering, or misfiring
- ✔ Difficulty starting the engine or a no-start condition
- ✔ Unexplained drop in fuel efficiency
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Communication errors with diagnostic scan tools
- ✔ Failure to pass emissions testing
