- Wiring harness
- Ecm
Common causes
- High likelihood: Increased friction in valve assembly
- Medium likelihood: Actuator force degraded
Possible symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- Reduced-power or limp mode may occur
