Possible Causes
- 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
- Main variable engine coolant pump circuit short circuit to ground, short circuit to power, open circuit, high resistance
- Control Module Signal Name
- Circuit reference O_T_VCLNTP Control
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Main variable engine coolant pump failure
