Can't figure out why I have p0102 code.

Question

My car is running poorly and I have the P0102 code. I changed the MAF, checked all of the wiring, and can't find a vacuum leak on my 09 Impreza. What else could be the problem?

HI there

If you testing the wiring to the computer and for power and ground, its possible you have a bad sensor. If you went aftermarket on the sensor it's very possible the sensor is no good. You need to make sure you check for continuity on the signal wire from the sensor to the computer.
