      Does anyone know what this sensor does and what would happen if it was "bad". The shop where my car is located said mine was bad although the car seems to be running fine (I think. I haven't drove it yet since they replaced my faulty blue coolant temp sensor). Any symptoms to watch for? How can I confirm that this sensor is bad?

      Not to take away from your topic, but has anyone ever thought about extending the temp sensor from the lower bumper (Im assuming its that grey nipple on the passenger side) to the intake tube? I havent done it since it probably only samples the temp like every minute.

      But to your question, I bet if you held a lighter somewhat near the sensor you would be able to check your MFA display to see if the temp changes......

      We are not talking about the same sensor. The one you are refering to is the ambient air temp sensor. That is the one that displays the outside air temp on the MFA. The one I'm refering to is the one that is screwed into the intake manifold on the driver's side right in front of the distributor.

      How well did it work? Am i right?..... it samples the air only every so often?

      Someone please save my hijacked thread (HAHA!!) and answer my original questions please.

      You would need the electrical specification for the temp sensor...so much resistance and such and such temperature....

      the ecu uses the intake temperature sensor to determine when and how much to retard timing to prevent detonation. If your timing was being pulled back unnecesarrily or not pulled back enough then the sensor MAY be the problem.

      look up the stock resistance for the sensor.(the ohm reading).

      test yours.

      it should be in the bently.
