Where the heck is the MAP sensor on my car? I need to replace mine and I can't seem to locate the old one. GM said it was part of the MAF sensor and yet I just bought a MAP sensor at the parts store. Hmmmmm.

 

You dont have a MAP sensor on your motor. You have a MAF sensor (which is located between the throttle body and the air filter).

MAP sensors came on cars equiped with speed density TPI (90-92 F-body's).

85-89 TPI F-body's came with MAF's.

 

If you have an 86 TPI, unless you or someone else has changed your system over, you do not have the MAP sensor. You have the MAF Sensor on your car. The MAF sensor is located between the air filters and the throttle body. What makes you think you need a MAP sensor anyway?

 

Because I have a code 33 coming up every now and then. My oil pressure gauge seems to be high untill the vehicle reaches operating temperature also.

 

That doesn't neccessarily mean that you need a new MAF sensor. You could have a broken or shorted wire between pin "C" of the MAF sensor (dark green wire) and pin "B12" of the ECM. That is the signal wire for the MAF sensor. I don't know how high your oil pressure is, but mine is usually up there around 50 or so until the oil warms up and starts to flow smoother.

 

My brothers car had the same code and it turned out to be a bad wire by the conector.
