P0112 Intake air temperature sensor reads too warm
P0112 means: Intake air temperature sensor reads too warm. This sensor tells the engine computer how warm the incoming air is. OK to drive, but have it checked soon. The repair usually costs about €40–200 in Estonia. The most common cause: connector or wire. Other possible causes: sensor has failed, MAF sensor, if the temperature sensor is built into it.
What it means
This sensor tells the engine computer how warm the incoming air is. It is often built into the mass air flow sensor. The sensor voltage is too low. Usually the wire is shorted.
What could be wrong
- 1Connector or wire
- 2Sensor has failed
- 3MAF sensor, if the temperature sensor is built into it
What you can check yourself
Check the sensor connector. You can keep driving, but fuel consumption may rise a little. You can do the simpler checks yourself.
How we fix it
- We compare the reading with the outside temperature
- We repair the wire or connector
- We replace the sensor
