Changed maf sensor because of p0113 code stillhave problem after i changed sensor battery light came on fixed bad belt could belt have caused the pcm to not read the 5v it needed to wor k the iat sensor?

P0113 is air temp circuit high. The maf sensor (mass air flow) sensor just measures the amount of air entering the engine. The iat (intake air temp) sensor is the one that detects the temperature of the air.
Change that sensor, and the code should disappear. It is located in the intake manifold or air plenum.

They share the engine wiring harness from the computer (called the PCM) and a common ground circuit, which is referred to as the signal return. So I think you need to look for a defective ground.

I would suggest to replace the temp sensor only and after clearing the codes test again and I am sure the problems will be solved.

Anonymous Nov 19, 2011

If the problem in the Coolant Sensor, and it is pulling down the other sensors. Can it be unplugged to test to see if the other will read or is ground (signal return) daisy chained together??? Granted the Coolant Sensor is only a $12 part, but wondering if that could be an easy way to test if you know.

Look for a vacuum leak, or an intale snorkle that is not attached.

They do share a common reference voltage. You can get a wire diagram from All Data (just get a short term subscription and print the diagrams for safe keeping) or you can get the real factory manuals from www.diyrepairmanuals.com that the dealers use. They tend to be more pricey than the diagrams you can download, but they also tend to be much easier to use.

You might want to check the idle control valve/idle air control valve too why your at it. However, it does sound like a bad pcm or grounding issue. Good luck.
