P2199 Intake air temperature sensor: readings don't match (sensor 1)

By: · Updated:

P2199 means: Intake air temperature sensor: readings don't match (sensor 1). A temperature sensor tells the computer the temperature of the air, coolant, fuel or oil. Drive gently and have the car checked soon. The repair usually costs about €30–200 in Estonia. The most common cause: faulty sensor.

What it means

A temperature sensor tells the computer the temperature of the air, coolant, fuel or oil. With a wrong reading the computer gets the mixture and the fan wrong.

What you may notice

  • Engine light on
  • Hard cold starts
  • The fan may run all the time
  • Higher fuel consumption

What could be wrong

  1. 1Faulty sensor
  2. 2Corroded or loose connector
  3. 3Broken or chafed wire
  4. 4Engine computer fault (rare)

Repair difficulty: Easy

What you can check yourself

Check the sensor connector and make sure it is clipped in. On a cold engine, compare the reading with the outside temperature. You can do the simpler checks yourself.

How we fix it

  1. We read the sensor on the diagnostic tool and compare it with other sensors
  2. We check the connector, supply and ground
  3. We repair the wiring or replace the sensor
