DTC P0112: Intake Air Temperature Sensor Circuit - Low Input: Condition

DTC is set when Intake Air Temperature (IAT) sensor voltage is lower than 0.16 volts for 5 seconds continuously. MIL is illuminated when ECM detects malfunction during first drive cycle. DTC is also set when intake air temperature is high and IAT circuit resistance is low. Possible causes are:

• Short to ground in circuit between IAT and ECM.
• IAT sensor malfunction.
• ECM malfunction.
