Possible Causes
- The powertrain control module has determined failures where some circuit quantity, reported via serial data, is not plausible given the operating conditions
- Charge air coolant pump is not reaching the desired position
- Charge air coolant pump circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Charge air coolant pump failure
- Wiring
- Mechanical integrity
- Installation
