Different maf sensors... and Pending PO650 01 Grand prix

[chicagochuck]

2001 Pontiac grand prix non supercharged 3.8 . I had a maf low circuit code p0102.. The rpm gauge would fluctuate at start up and If you tapped on the sensor itself the car would want to shut off.


I found a old maf senor I had from a 98 regal supercharged and installed it in my 2001 Pontiac grand Prix..I have not driven it much but so far it hasn't idled rough at start up like previously, and the code hasn't came back yet.... Would this be wise to do?

For the 98 and my 2001 it is two different design Maf sensors but they bolt up the exact same.....


Also My Mal indicator light does not work and I get a po650 code...I'm not sure if It could be bulb..wiring etc.

you have to run a 99+ MAF sensor.

98 and down is different than 99+

Yea I noticed that.... It ran fine but I'm not going to continue to run it with the older sensor. Thanks

I believe it'll read different frequency. Correct me if I'm wrong guys

[matt5112]

Did it look different or what?

[chicagochuck]

Yes it looked different, One has a longer housing. I just wasn't sure if it was a different design..Now I know

Anyone know about the Po650 code?

[matt5112]

no clue. what does google say about it?

[chicagochuck]

I know its a fault with the Malfunction indicator indicator system..Maybe the light bulb is bad..(it doesn't work). I hope that's all it is..but it could be the system or computer....
