P02F4 Cylinder 7 Injector Circuit Range/Performance
The cylinder 7 injector drive circuit is electrically OK but the response (current ramp, dwell time, or peak voltage) does not match the calibrated profile — typically a high-resistance solenoid winding or wiring corrosion.
Is it safe to drive with P02F4?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
Common causes
- Most likelySolenoid winding ageing
- Less likelySensor element aged beyond calibration window
- Less likelySensor mounting loose - signal damping
