What can I use to clean my intake air temperature sensor?

What can I use to clean my intake air temperature sensor?

They recommended a spray solvent made by CRC called “QD Contact Cleaner.” You can get it at Lowe’s and Home Depot, in the electrical area. I got some and cleaned the MAP and temp sensor and bingo: instant smooth idle.

What does an air charge temp sensor do?

The Air Charge/Manifold Temperature sensor is used by the computer to measure air density for fuel mixture control. The computer uses this information to trim the air/fuel ratio according to the air density.

What causes an intake air temperature sensor to go bad?

Over time the sensor can “go bad” due to a buildup of oil and debris, or it just simply needs replacing at a certain point. Ongoing inspections can help keep issues involving the IAT sensor at bay.

What should intake air temp be with engine off?

With the engine off, measure the sensor resistance across its terminals. At about 68 F (20 C), you should get around 37K ohms At about 86 F (30 C), you should get around 24K ohms Plug in the sensor electrical connector.

How can I test my air temperature sensor?

You can test an intake air temperature sensor using a digital Ohm Meter set on the DC volts scale. Turn the IGN switch to the ON position and backprobe the return wire to see the voltage being reported to the PCM/ECM. You can also test the sensor’s resistance, but that’s not as accurate as reading the actual return voltage.
