P011C – Charge Air Temperature/Intake Air Temperature Correlation Bank 1

P011C Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P011C Possible Causes

Faulty Intake Air Temperature (IAT) Sensor 1,Faulty Intake Air Temperature (IAT) Sensor 2,IAT Sensor 1 or IAT Sensor 2 harness is open or shorted,IAT Sensor 1 or IAT Sensor 2 circuit poor electrical connection

P011C Description

The Intake Air Temperature (IAT) sensor is built-into mass air flow sensor. 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.
