Air tempt sensor is usually in the intake air hose/air filter.

What is the problem with it?
Most problems with them s it being left unpluged after service work.
Look for a wiring plugin around intake air duck work or air filter unpluged.

I would like to put a resistor across it. I can either put it on the ATS or the CTS (coolant temperature sensor) It is probably easier to put on the CTS.
Do you know where the CTS is located.

Thanks Andy

Leave it alone if it is working.
Putting a resister on it will mess up the fuel mix and erngine running and is illegal.
