SOURCE: Check engine light has come back for the second time after having change the air filter and resetting. Now receiving a code: P0101 What do I do now?

Probably carbon build up on a sensor. Had this happen on a Ford Expedition. I put it on the highway and hammered it several times. It blew the carbon off the sensor. Light went away.

2005 KIA Rio belts have been making noise. Now check engine light is on and I get codes p0101, p0101 pending, and p0170 pending?


The belt tensioner is defective. It automatically keeps the belt at the proper tension. P0101 - MAF sensor (mass air flow sensor) or circuit problem. P0107 - MAP sensor (manifold absolute pressure sensor) signal is low.

Basically the P0101 diagnostic trouble code (DTC) means that there is a problem with the Mass Air Flow (MAF) sensor or circuit.

P0170 means there is a malfunction in the computer's control of the air:fuel ratio.
