Fault code 17748
Ok where do I start? A4 2.0lt SE 2001 B6
My o2 sensor has been faulty for a while now to which I replaced the other day. Only thing is and i'm not sure if it matters, I replaced it with a second hand one from a car that had been in a rear end smash however the sensor was working fine prior to removal.
So now I have idle/running issues.
Hot or cold car runs very nicely when MAF is unplugged and very very roughly when plugged in (barely wants to start when cold).
Would suggest that the MAF is faulty Yes?
However the fault code coming up is 17748 - Camshaft Position Sensor (G40) / Engine Speed Sensor (G28): Incor. Correlation
P1340 - 001 - Upper Limit Exceeded
Timing marks are spot on Checked double checked and checked again!
So I run the car plugged in the VCDs run the measuring blocks but not sure what I'm looking at, perhaps someone can help explain
