P0114 OBD Code Definition:
P0114 Intake Air Temperature Sensor 1 Intermittent or Erratic
P0114 OBD Code Description:

OBD2 Code P0114 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 P0114
– Engine Light ON (or Service Engine Soon Warning Light) Possible Causes

Possible causes of P0114
– 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
