Was bedeutet der Fehlercode?
The engine control module (ECM) monitors exhaust gas recirculation (EGR) and sets the fault when the flow is too high. The code is an information code for an algorithm fault in the control module and does not point to any single component. Although the code is named as insufficient flow, the condition is excessive flow.
Mögliche Ursachen
- No specific cause is listed for this particular code
Was Sie tun können
- 1If other fault codes for the air system are stored alongside this one, troubleshoot from those first
- 2Read and clear the fault code, then see whether it returns with the engine running
- 3If you have a diagnostic tool, compare the EGR valve position at idle with the value under throttle and check that it follows the throttle
- 4Check that the EGR valve is not sticking from soot or dirt
- 5If the fault returns with no other air system codes, have a workshop read out the control module
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
