Cylinder 10 Injector Leaking
The P02C1 code indicates that the fuel injector for cylinder 10 is leaking, causing excess fuel to enter the cylinder. This can lead to misfires, rough idle, increased fuel consumption, and potential damage to the catalytic converter or engine. The leak may be internal (into the cylinder) or external (fuel leak).
1. Most Common Causes
- Faulty fuel injector (stuck open or leaking seal)
- Damaged injector O-ring or seal
- Cracked injector body
- Contaminated fuel causing injector sticking
2. Symptoms You Will Notice
- Rough idle or misfire on cylinder 10
- Strong fuel smell from exhaust or engine bay
- Decreased fuel economy
- Check Engine Light illuminated
- Possible fuel leak near injector
3. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P02C1 is present.
Step 2: Perform a fuel pressure test to check for excessive pressure drop.
Step 3: Use a stethoscope or injector tester to listen for leaking injector on cylinder 10.
Step 4: Remove injector and inspect for damage, cracks, or worn O-rings.
