Possible Causes
WARNING: This page is about a different variant/trim than selected.
- Electrical Cause
- Yes
- Mechanical Cause
- Yes
- Control module cavity
- Circuit reference O_T_WCAC
- The powertrain control module has determined an open circuit through lack of bias voltage, low current flow, no change in the state of an input in response to an output
- Charge air coolant pump circuit open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Charge air coolant pump failure
