What Is a Car ECU?
The Engine Control Unit (ECU), also known as the Powertrain Control Module (PCM) or Engine Control Module (ECM), is the “brain” of your car. It controls fuel injection, ignition timing, emissions, and other critical engine functions. A faulty ECU can cause poor performance, stalling, or even prevent your car from starting.
Symptoms of a Bad ECU
Check Engine Light (persistent or flashing)
Engine Misfires or Stalling
Poor Fuel Economy
Car Won’t Start (no spark or fuel delivery)
Throttle Response Issues
