P01E0 — Cylinder 11 Injection Timing Performance - Over Advanced

The controller reports cylinder 11 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 fuel pump has failed. Check code applicability and monitoring conditions in the specific vehicle's manufacturer 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: P01E0-00, P01E000, PO1E0 (some scan tools add the fault-type byte, e.g. -00).
