Code 24???

[YoNkErS87t]

What could cause this code to be thrown. I didn't even know the car had a intake temp. sensor or what ever it is.

Any Idea guys???

No help?

Bad AFM most likely.

we ran the car without the HAC, could this cause the code.

According to the TSRM removing the HAC will result in it's own code, a 35. Either way, try plugging the HAC back in, resetting the ECU, and see if the code goes away.

I'll try that and let you know what happens.

Thanx bishop and welcome back.

The AFM has both a temperature sensor and an air flow sensor in it. The way to check if you have a bad AFM is to pull it off the car and take a ohm meter to it. The specific resistance of the various channels should be given in the TSRM:

code 24=bad afm, afm circuit wiring or ecu. Check the afm sensor with a multimeter or swap it out for a different one and work your way up. Most times its just the afm sensor.
