Intake Air Temp Sensor

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Okay I'm now sorted with a Windows laptop and a USB OBD Cable.

I have 4 error codes.
Active Carbon Filter error - no surprise there as the valve and filter is in the cellar.
Vehicle Speed Signal Missing - again no surprise but will be fixed very soon
Intake Air Temp Open/Short - The wires look okay
Intake Air Temp electrical error.

How can I check if the temp sensor is working okay, is it likely to be some sort of thermistor device?
Should I expect to find 12v on one connector and ......

Cheers
TAD

	I'm assuming you've cleared the codes, took it for a run and then tested again? What engine is it? I'm assuming AGG since you've got OBD. To test the wiring (assuming my wiring diagram is correct) Test the resistance between pin 1 of the connector (Green and blue wire) should to pin 36 on the ECU plug, and pin 2 to the engine block ground. Both should be more or less 0 ohms. (1 maximum, ignoring the resistance of the multimeter leads) My diagrams were incorrect - here's what autodata has to say: Pin 1 on the sensor is a White and Yellow wire, and it goes to ECU pin 37. Pin 2 on the sensor is a Brown and Blue wire, and it goes to ECU pin 29. Test the resistance between the ECU connector pin and the sensor pin, you should get under a couple of ohms. To test the sensor, stick the multimeter over both pins. I don't have the exact values off the top of my head, but it should read somewhere between 100 and 100k ohms - anything outside this and it's deffo completely shafted. Within these it might be OK or it might be out of calibration, but the ECU probably wouldn't claim it was open/short. If you want an engine wiring diagram, there's some here: http://www.keepandshare.com/doc/show.php?i=1501135&cat=7&fclick=y No idea who hosts them, but I downloaded them for my conversion. He's password protected the file, but I cracked the password, its 4672. Edited by cobblers - 11 Jul 12 at 13:45

	It's an ADY motor. The codes returned after resetting and a run. The actual codes are: 0124730 0062516 0052330 00523157 Thanks for the diagrams, my motor is not on there.
	Bollocks to it all!!

	IIRC ADY engines run the same ECU. I think that's what my AGG identifies itself as over vag com, too. Edited by cobblers - 11 Jul 12 at 13:52

	ADY's were a kind of hybrid - 2E internals, AGG fueling/intake
