Loves his Sprinter
Hi,
I've wandered over here from the T1N section where I live, as I've had a customer in with a sprinter he asked me to look over - with my limited diesel knowledge (we build race cars!) we popped it on our diagnostic and had a load of codes.
It was recovered to us with an EGR fault, according to breakdown assistance, but we have lots of codes.
The interesting one is:
(Note - on my diagnostic, the codes come up strange, i found by dropping the last two digits, it was about right!)
04091C - P0409 Exhaust Gas ReCircuitulation Sensor A Circuit
033567 - P0335 Crank Pos Sensor Circuit
012200 - P0122 Throttle Pos Sensor Voltage Low
069716 - P0697 Sensor Ref Voltage C Circuit/Open
034431 - P0344 Camshaft Pos Sensor A Circuit Interm Bank1 or Single Sensor
03442F - ?
212714 - ?
211217 - P2112 Boost Pressure Servo Motor Circuit Open Circuit_
008700 - P0087 Fuel Rail/Sys Press-Too Low
Some I do not have a reference for.
Van is a 2010, 4 cyl diesel, I think a 313. All of the codes returned at startup after clearing. If you get to the throttle quickly, it will rev, but then ESP light comes on, sometimes it will not rev at all, other times it will, but take 5 seconds or so to reach 3krpm.
Interesting though, I see the reference 5v error, checked the wiring diagrams thinking there are all on the same ecu pin, and they are not, all of the sensors above have 4.99v at them, so not quite sure what is going on.
Customer wants to replace ECU - not sure if the immobiliser is in it and he would need other parts, but the ECU "used" is £400 - and not sure if that is where I would start, I tend to agree that it is indeed an ECU problem, I have checked the wiring loom and it all looks ok, battery tests ok, fuses, etc...
I saw a post when I searched that the cam / accel sensor use the same reference wire, but I have 5v at these sensors, sadly I do not have the diagnostics to retrieve live data from the engine whilst running...
Any wise thoughts anybody?
Thanks
