Hi.
Crafter with P0236,P0237 error. We replaced MAP sensor, intake manifold and EGR.
After replaced reset system and live data showing 100 kPa manifold pressure.
For first 5-10 min drive ok but after on idle an errors appears and car loosing power.
Errors presents even on ignition On. Error detail showing :

,,Charge air cooler inlet: pressure sensor 1 bank 1: raw value: 370 mbar''

Is the above pressure read by the MAP sensor?

The car haven't got charge pressure sender (boost sensor) - G447 - I was checked this with VW local dealer.

However with MAP sensor removed from intake manifold but connected only electrical and engine running and accelerate I can see with vcds ,,charge air pressure value is going up from 370 kPa to to 670 kPa.


Should I focus on MAP sensor ? I already checked 5 [V] reference and earth to connector is ok.
I can not find wiring diagram for this engine- If I know which pin of ecu connector is signal form MAP I possible can by-pass and test.
Or this is related to heater resistance in wiring
Thanks for any help
Marek

If I know which pin of ecu connector is signal form MAP I possible can by-pass and test.
For DAUB engine the reported sensor G31 (GX9) signal wire (green/purple all the way) connects into ECU connector T60e pin 39. Sorry but I'm not sure what's the referred MAP sensor.

However, I'm more inclined that the culprit is the sensor below
Manifold Pressure / Boost Sensor (G31)
...
Engine RPM: 0.00 /min
...
Charge air cooler inlet: pressure sensor 1 bank 1: raw value: 370 mbar
Engine stopped (or even idling) the raw value should read close ambient air pressure - near 1000 mbar.
I'm fairly confident the value doesn't curently change at all even engine is revved. I believe it can be read at IDE07738 also on this engine.
