What if voltage regulator in pcm is bad?
If the voltage regulator in the Powertrain Control Module (PCM) is bad, it can lead to inconsistent voltage supply to the PCM and other electronic components in the vehicle. This may result in erratic engine performance, poor fuel efficiency, and malfunctioning sensors or actuators. In severe cases, it could cause complete failure of the PCM. It's important to diagnose and replace a faulty voltage regulator promptly to avoid further damage to the vehicle's electrical system.
