Description

Fuel injector cylinder 10 (N300), circuit malfunction

Common Symptoms

• Check Engine Light with cylinder 10 specific code (V10/V12 engines)
• Misfire detected in cylinder 10
• Engine roughness particularly noticeable in high-cylinder-count engines
• Reduced overall engine power output
• Poor engine smoothness and refinement
• Increased emissions from affected cylinder

Possible Causes

• Failed fuel injector for cylinder 10
• Electrical fault in cylinder 10 injector circuit
• Open or short in cylinder 10 injector wiring
• Poor electrical connection at cylinder 10 injector

• Wiring harness damage specific to cylinder 10 location

Diagnosis Steps

1. Swap injector between cylinder 10 and another cylinder if possible
2. Perform electrical continuity test on cylinder 10 injector circuit
3. Measure resistance of cylinder 10 injector coil
4. Verify injector pulse signal with diagnostic equipment
5. Inspect wiring and connectors in cylinder 10 area
6. Test ECU injector driver output for cylinder 10

Repair Solutions

• Replace faulty cylinder 10 fuel injector
• Repair wiring issues in cylinder 10 injector circuit
• Clean or replace damaged electrical connectors
• Replace ECU if cylinder 10 injector driver circuit is defective
• Repair damaged harness sections affecting cylinder 10
