Pull code 48 MAF Ckt,, is that a MAF Sensor???

Will a MAF from a 00 Z28 work to make sure that this is the problem??? My car is OBD-1 and the 00 is a OBD-11...

 

Im not sure of the difference if any in the two but you can check a couple things if you have a volt meter. Terminal C should read 12vdc to ground, Terminal B should read continuity to ground with 0vdc potential. Check continuity between the sensor and the PCM from term A to the PCM. Also that wire should be more that 4V and less than 6V. Anything more or less can indicate a wiring problem or faulty PCM.

 

One more thing, That code can be caused by a vacuum leak. The manual says to check short and long term fuel trim for being in the optimal range(both banks).

 

Thanks for the reply!!!

Well I pulled it of my 95 and put it on the 00 and the 00 would not start... So I took it off again and looked at it, well low and behold the f****** eliment is broke...

 

Well I put a new MAF Sensor in and the car started!!! It nice to hear the car run again... Its the first time i've heard the car in over a year!!!

 

I'm glad you got it going. Drive carefully.
