Cylinder 6 Alternative Fuel Injector Control Circuit Range/Performance
Cylinder 6 alternative-fuel injector is electrically OK but its response (current ramp, dwell, peak voltage) is off-spec — typically winding ageing.
Affected components
- Alternative fuel injector
Common causes
- High likelihood: Winding ageing
- Low likelihood: Sensor element aged beyond calibration window
- Low likelihood: Sensor mounting loose - signal damping
Possible symptoms
- Check engine light on
- Misfire or rough idle on the affected cylinder
- Increased fuel consumption
- Possible fuel smell or smoke from exhaust
Diagnostic notes
