Code P119, Open/Shorted Fuel Injector: Action
Faulty injector disabled for engine run cycle.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- Checks for intermittent. If second digit of PD17 is zero, fault is not present. PCM snapshot should show PD17 second digit as "1".
- Checks for short to ground on circuit No. 339 or 439.
- Open may be caused by poor injector harness connector contact. Check terminal contact.
- Use fuel injector override to pinpoint faulty injector circuit. Disabling one injector would normally create a noticeable difference in engine RPM or idle quality.
- Checks for open or short to ground in circuit to PCM.
- Checks injector resistance at engine temperature when the condition occurs. Injector resistance will normally increase with increasing engine temperature. Normal injector resistance should be 8-25 ohms.
- Checks if problem is with injector or fuel rail harness.
- Checks if problem is shorted injector or a short in fuel rail harness.
- Checks for open or high resistance in fuel injector rail harness or open or high injector resistance.
