Engine Management System
by davecrawf Sun Aug 06, 2023 4:36 pm
My engine warning light has been on since leaving Spain in March this year. Using an OBD I have obtained two error codes
1. P0401 EGR Flow insufficient
2. P0638 Throttle Actuator
I have managed to resolve (1) by repairing a split pneumatic hose. However I cannot understand why I have error code (2)
There are no issues with the actual running of the vehicle. I would just like understand and resolve the warning system.
Does anyone have experience of such things and can help me please.
Much appreciated

Could it be related to the EGR fault? Perhaps the TB sensorneeds resetting. Disconnecting the battery for >5 mins might cure it.

Poss unnecessary but I'd check I had the radio codes before disconnecting the VB?
