What P0113 means
The intake air temperature signal is reading higher than the plausible range, usually an open circuit.
Common causes
- Failed IAT sensor
- Open or corroded wiring
- Poor connector contact
How it is usually fixed
- 1Inspect the connector
- 2Test sensor resistance cold vs warm
- 3Replace the sensor if out of range
