What drivers and mechanics usually notice.
These are practical, workshop-style symptom phrases written for search and support conversations. They are not a substitute for live diagnostic data.
Cylinder 2 misfire and vibration at idle
Torque contribution from cylinder 2 too low
Engine cuts out at higher RPM
White smoke puff at idle after running hot
Slow throttle response and reduced torque
Why B132 usually fails
- Open circuit at ECU pins or pump connector.
- Short to ground in the harness.
- Pump-unit internal leak or weak hot solenoid.
- Cylinder 2 nozzle clogging from fuel contamination.
Before replacing the part
- Swap-check logic should be supported by wiring tests; cylinder-specific faults can be harness faults.
- Look for uneven black smoke or rough idle that improves above 1200 rpm.
