P0113 code
 

Need help with ECL and engine code P0113. Is this a MAF/Intake temp issue? Just replace the MAF in the intake with a new sensor? Please advise. Thanks! Oh by the way 06 LS with 120k miles.

First: are you sure it wasn't P0013?

Second: have changed the air filter recently?

If it is P0113 yes , your MAF is probably bad or,
Everybody has forgotten to re connect the MAF sensor.

Yeah, P0113 was the code, and thanks for the feed back.

Could be a loose connection or dirty MAF sensor

I'm going to change the MAF sensor and air filter today, along with some new plugs. Hopefully that will allow me to reset the codes and get the CEL off. Thanks again for the help!

Please not some new plugs, AC Delco 41-103 iridium plugs!

Don't "clear" the codes, let it do it for itself!

If replacing the parts fixes things the codes and CEL will mend themselves, probably in less than 10 drive cycles.

yeah reference code came back after replacing sensor and clearing codes voltage across the IAT sensore is showing -40 DegF with key on and engine not running. Anyone have the Mass Air Flow /Intake Air Temp sensor pin reference voltages and wiring color? Maybe broken wires... hope its not a bad computer:sad:

Like this?

If you don't already know: low ref= less than 5V (ground,0V), ref=5V
