P0113 Intake air temp sensor g42 P0113 00 [172] - Signal too High

[k1ke77]

Had this error code, cleaned the IAT/MAF sensor but error still came back. I ordered new Sensor and replaced the old one but still getting the same errors.

Does any one know what kind of resistance and voltage i am supposed to get on the pins at the connector of IAT/MAF?. Or can someone tell me the pin numbers/color on the ECU so i can try tracing the the wires?

Or if you can suggest key words to google i would also apreciate that.

Thank you for your help in advanced

found this for a B5 would the pins still match?


Four wires to MAF.

Pin 2 comes from fuse S231

Pin 3 goes to terminal 50 at the ECU

Pin 4 goes to terminal 40

Pin 5 goes to terminal 82

The ECU connector is the 94 pin one, which should be the larger of the two.

little late for a response..just trying to help maybe someone else..Check the g42 ( map, air temp/charger, part #
