Hi,
I have two problems with my Mercedes, both of them are related to "Check Engine Light". The car is C180 Kompressor, 2002 year, M271 engine + LPG.
So, below is the list of errors:
Actual:
P0020: "A" Camshaft Position Actuator Circuit (Bank 2)
P0170: Fuel Trim (Bank 1)
Pending faults...
The continuing saga of my sons Alfa 156 continues. I have finally got hold of software to read the codes and it through up ' Fuel trim P0170' and further stated ' the ecu has received a high value signal from the sensor' My question is what does Fuel trim P0170 relate to ? Lamdba? pressure? any...
