Was bedeutet der Fehlercode?
The engine control module has received too low a signal from the needle lift sensor. The fault is recorded as intermittent, meaning it comes and goes, and may not be present right now. It can cause poor acceleration, a sluggish engine and knocking at idle, and boost pressure and exhaust gas recirculation are limited.
Mögliche Ursachen
- The signal wire is shorted to earth
- Break in the signal or earth wire
- Contact resistance in the connections
- Faulty needle lift sensor
Was Sie tun können
- 1Check the wires and connections to the needle lift sensor for chafing, play and corrosion
- 2Because the fault is intermittent, road test the car and note the engine speed, load or temperature at which the problem appears
- 3Measure with a multimeter that the signal and earth wires to the needle lift sensor have no break, and that the signal wire is not shorted to earth
- 4Clear the fault code and road test the car. If it returns, have a workshop with diagnostic equipment investigate the needle lift sensor and the engine control module
- 5Replacing the needle lift sensor is a workshop task
Symptome, die Sie bemerken können2
- The car accelerates poorly and feels sluggish
- The engine knocks at idle
Was der Fehler beeinflussen kann2
- Boost pressure is limited to the basic level
- Exhaust gas recirculation (EGR) is switched off
