Just finished installing the ko4 and got a code for my maf and the traction control light is stuck on. The code is 16486.p0102 mass air flow circuit low input. Could this and the traction light have anything to do with the install? The battery was never unplugged either.

Yea the maf is plugged in. The only things I unplugged is the maf n75 coolant reservoir and o2 sensor so I don't understand how traction control is associated with any of those

because traction control is disabled when the MAF sensor reading is either not present (no reading) or exceeds the sensor maximum (implausible signal).

Cleared them once and it came back. I'm gonna check to make sure I didn't put the maf on backwards but I really doubt that

how did you manage that? the connector is keyed like most connectors on our car - square on one end and round on the other; you shouldn't be able to put it on backwards Originally Posted by mattg1.8
