Help with MAP & MAP sensors
Discussion
Hi, I'm hoping someone can help me out solving 2 codes; P0101 & P0069 (img. att.)
So far I've had a leak test done (none found), "professional" diagnostics (they thought it could be an air leak or turbo), checked for play in the turbo, had the DPF checked (95% healthy) and changed both the MAP & MAF sensors.
More recently I've started testing the sensors as I noticed the OBDII reader said MAP pressure was 21psi before the engine was even started.
I found that the MAP earth resistance was 100ohm, the top pin was 5.5V & the 2nd pin was 5V. All with key on but engine off.
So, my question is has anyone solved this before? My next guess would be to hunt down the earthing points and check them?
