Code P0110 Toyota Description

The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM). The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.

Discuss the causes and fixes for P0110 Toyota OBDII Code

  • yes a good explaination but when I put a new sensor in it still showed the same code...now what?

  • Next step is to check the sensor connector and the wires from the sensor to the the Engine Control Module (ECM)

  • does that sensor make the engine miss randomly? Checked the wires will check them again. thank you.

  • Although it's possible, it's very unlikely. I haven't seen a bad intake air temperature sensor causing any misfiring or any other engine performance problems.

  • engine light on 97 toyota tacoma 2.4.shows code p0110 starts up runs then shuts off but starts rite back up does that a few times then it will idle

  • Looks like you have a problem with the Intake Air Temperature (IAT) sensor. You should start by replacing the sensor.

  • i also put a new maf sensor on my toyota tacoma.but it was an after market one.would that make a diffrence?

  • this car is remove black smoke I hv p0340 nd p0110 toyota camry 1996 model what can I do to fix the problem

  • If you have the P0110, then you have to replace the Intake Air Temperature Sensor. The sensor is mounted on the air filter box.
