Co oznacza ten kod błędu?

Although the code is named position sensor for intake air flow, it concerns the signal from the EGR valve position sensor. The engine control module monitors the EGR valve's function and logs a fault when the signal is incorrect or unreasonable. The fault is intermittent, so the signal comes and goes. The causes are loose or poorly contacting connections, or a damaged EGR valve.

Możliwe przyczyny

Loose connection
Contact resistance or oxidation in the connections
Damaged EGR valve

Co możesz zrobić

1Read the fault code, clear it and road test. If it does not return straight away, the fault may be intermittent
2Check that the connectors to the EGR valve position sensor are fully engaged and free from oxidation
3Follow the cable from the EGR valve and look for chafing, pinched sections and loose clips, especially where it moves
4If you have a diagnostic tool, read the EGR valve position value in live data with the engine running and see whether it jumps erratically
5If the fault returns, have a workshop with diagnostic equipment check the EGR valve and decide whether it should be replaced
