P2C8D — DC/DC Converter Temperature Sensor D Circuit Range/Performance
The ECM detects a range/performance fault on the dc/dc converter temperature sensor d circuit. Reading cannot be used reliably for control.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Dcdc converter temp sensor d
- Wiring harness
- Dcdc converter
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- Sensor characteristic drifted
- Sensor mounting displaced
- Sensor element aged beyond calibration window
