P01D0: Cylinder 3 Injection Timing Performance - Over Advanced — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
The controller reports cylinder 3 injection timing as more advanced than the monitor's accepted range. The code describes a timing-performance deviation, not proof that an injector, sensor or pump has failed. Confirm the code's applicability and monitor conditions in the vehicle service information.
Affected system: Powertrain
Symptoms
- Warning light may illuminate
- Related system function may be impaired
- Vehicle-specific symptoms vary
Possible causes
- Fuel supply or pressure issue, restricted injector, actuator fault, connector or wiring damage
- Related wiring, connector, power or ground fault
- Vehicle-specific mechanical or control issue
What to check
- Record stored and pending codes and freeze-frame data
- Check fuel supply and pressure readings, electrical supply and ground, and the relevant injector or regulator circuit before replacing parts.
- Confirm measured values against the vehicle service information
- Retest under the conditions that set the code
- Check fuel supply and pressure readings, electrical supply and ground, and the relevant injector or regulator circuit before replacing parts.
- Repair the verified cause and confirm the code does not return
Also written as: P01D0-00, P01D000, PO1D0 (some scan tools add the fault-type byte, e.g. -00).
