Year of Manufacture *: 2011
Engine Size and Code *: 2.0 CAAA
( Optional ) Scanner Used: vagcom
( Optional) Fault Codes: P0236,P0651
Vehicle going into limp mode, fault codes 4124(P0651)sensor reference voltage B open circuit and 11901(P0236)manifold sensor/boost sensor(G31) implausible signal present.Basically loosing 5 volt reference to boost pressure sensor, have load tested wiring which is ok, also snipped wire at ecu multiplug and voltage still drops to 0 under load so looks like ecu fault.
The wire which is green travels from sensor to ecu pin 30 with no splices,so what i am trying to find out is wether this reference voltage is linked in the ecu internally to any other sensors which could be affecting the voltage.Any information would be gratefully received as so far i have drawn a blank on information.
Regards Alwyn
