Co oznacza ten kod błędu?
The ECM monitors the circuit to the injector for cylinder 1. The fault code is set when the signal in that circuit is too high, which can be caused by a wire shorted to supply voltage or a damaged injector.
Możliwe przyczyny
- Signal wire short-circuited to supply voltage
- Damaged injector
Co możesz zrobić
- 1Read and note the code, clear it and road test to see whether it returns
- 2Inspect the wire to the injector for cylinder 1 for chafing and pinching where it may have shorted to supply voltage
- 3Use a multimeter to check that the wire to the injector for cylinder 1 is not shorted to supply voltage with ignition on
- 4If you have a diagnostic tool: read the signal for the cylinder 1 injector in live data with ignition on and see whether it is abnormally high
- 5If the wire is intact, have a workshop check the injector
Objawy, które możesz zauważyć2
- The malfunction indicator lamp (MIL) is on
- The engine is not running on all cylinders
