MAF sensor wiring S70

Apr 08, 2008 1 Replies
1998 S70 T5 and I've replaced the MAF sensor with a part from another car that it is known good.

Yet, I still get a check engine light after driving for a while so definetly not the sensor.



Is that harness often faulty?



Is it easy to replace?



Anything else that's a possibility?



It may be heat related the way it's acting and I saw on some earlier cars there is a thermostat that controls the air filter temp?.....but see nothing like that on my 1998.



Appreciate any thoughts. Thanks.


Also, has anyone seen the "altitude" or barometric pressure sensor go bad?

The code I get actually refers to this part but like I say, the check engine light will go out with the MAF sensor cold and the battery disconnected.

I can run for days/hours before it comes back on -- unpredictable.
