Does anyone have the wiring diagram that goes with this MAF sensor connector and can tell me what voltages I should read across the pins. I can’t seem to get any readings and am currently blaming my probe pins for not reaching far enough. Have some new ones on order. Just wondering if on this model they swapped to a Digital sensor, which I have no experience of testing, although my FLUKE 110 meter has a frequency setting? Any insight appreciated.

Thank-you, that’s very useful to know. I’d assumed that as I could feel the blow-back the sensor was just confirming it wasn’t getting the airflow it wanted. I assume that situation would throw up a different code?

Anyone had an issue where you can feel air coming back in front of the Mass Airflow sensor, where the air filter is and perhaps even get a P0100 error code. The car still runs well with no loss of performance that I can detect. The timing belt has been renewed and re-checked. There are no other errors that indicate VVT issues, so I am starting to assume worn cams or an intake valve issue. Would welcome advice on the next diagnostic check to perform - compression test, inspection camera in the oil filler hole?
