The Engine Computer (ECU/ECM/PCM) is your vehicle's brain, controlling fuel injection, ignition timing, emissions, and overall engine performance. A failing ECU can cause check engine lights, poor fuel economy, starting issues, and erratic engine behavior.
Signs of Failure
- Check engine light stays on
- Engine won't start or hard starting
- Poor fuel economy
- Rough idle or stalling
- Transmission shifting problems
- Failed emissions test
- Random misfires
- Reduced power or limp mode
Replacement Info
ECU replacement requires matching the unit to your vehicle's VIN. Some units are plug-and-play while others need dealer programming. Used OEM units from the same model year and engine are often preferred as they may not require reprogramming.
Time: 30 min - 2 hours (plus programming time if needed)
Difficulty: Moderate - Easy to install, may need programming
