code P0102

I think maybe your connectors to MAF or throttle body are not seatin g right. Maybe try electric cleaner and spray on the connectors. They could be dirty

 

Any luck on this? Having the same issue. For me I think I need to replace the wiring harness in the MAFS.

 

I have the same issue. My MAF was reading below spec on the scan too so I cleaned the intake and sensor. Did work. Replaced the sensor and still have a code. The new sensor reads a little closer to spec but still under spec.

 

Do you have an aftermarket intake?

 

Stock no vacuum leaks found.

 

What is your MAF reading at hot idle? Should be right around 4 grams per second (g/s).

 

It is 3.8-4.5. It's about 11 at 2000 rpm when it should be over 13 and that with the new MAF. The old was read 10

 

I can grab a "known good" 2k RPM reading off mine in a bit but readings off idle aren't all that useful as they can vary greatly and there isn't really a specified "good value".

The 2 best tests for MAF sensor accuracy is the idle reading and then what's known as a VE test.

The VE test is basically a WOT pull through 1st gear while recording Peak MAF, Peak RPM, IAT, and Barometric pressure then entering them in the calculator below.

While driving or in Park/Neutral?

 

The VE test is a driving test.

Mine is reading 3.8-4 g/s @ 700RPM ac off and about 11 @ 2000 RPM.

 

Everything looks good still have a code with no engine light. Truck runs mint still hesitates on hard take off. No lack of power no problem shifting or Hwy driving.
