OBD-II Trouble Code Description for P0114 Opel

Intake Air Temperature Sensor 1 Circuit Intermittent

What does this mean?

OBD2 Code P0114 Opel definition:
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.

Symptoms

Possible sumptoms of OBD code P0114 Opel
– Engine Light ON (or Service Engine Soon Warning Light)

Causes

Possible causes of OBD code P0114 Opel
– Dirty air filter – Intake air temperature (IAT) sensor harness is open or shorted – Intake air temperature (IAT) sensor electrical circuit poor connection – Faulty intake air temperature sensor The Error code is generally activated on detection of the following conditions: The Engine Control Module (ECM) detected an erratic signal from the Intake Air Temperature (IAT) sensor during the system monitor test

Possible Solutions

Check IAT cabling Clean IAT or MAF sensor Replace IAT or MAP sensor
