Code P1628 Chevrolet Description
The P1628 Chevrolet code indicates a problem with the powertrain control module's engine control temperature pullup resistor conditions. The powertrain control module (PCM) is responsible for regulating various engine functions, including monitoring the engine's temperature. The engine control temperature pullup resistor is a component that helps the PCM accurately measure the engine's temperature. When this code is triggered, it means that the PCM has detected an issue with the signal from the temperature sensor, possibly due to a faulty resistor or wiring issue. This can lead to inaccurate temperature readings, which may result in poor engine performance, reduced fuel efficiency, and potential overheating.
Common Causes of P1628 Chevrolet
- Faulty engine control temperature sensor
- Damaged wiring or connectors related to the temperature sensor
- Failed engine control temperature pullup resistor
- PCM software issue
- Electrical issues within the PCM system
Symptoms of P1628 Chevrolet
