Sensor IAT (Intake Air Temperature)

Circuit Malfunction IAT (P0111)

If the intake air temperature is higher than the engine coolant temperature of 40 ?� C with the ignition on, the PCM determines that sensor circuit in the IAT there is a malfunction.

Low level input circuit of the pressure sensor in the intake manifold (P0112)

The PCM monitors the input voltage sensor IAT. If the input voltage to the output unit 2E PCM - below 0.2 V, the PCM determines that sensor circuit IAT has a fault.

The high level of the input signal chain intake air temperature (P0113)

The PCM monitors the input voltage sensor IAT. If the input voltage at terminal 2E unit PCM - above 4.8 V, the PCM determines that sensor circuit IAT has a fault.

The low level of the input circuit of the coolant temperature (P0117)

The PCM signal controls the coolant temperature sensor at terminal block 1M PCM. If the voltage of the coolant temperature sensor - lower than 0.2 V, the PCM determines that circuit coolant temperature sensor has a fault.

The high level of the input circuit of the coolant temperature (P0118)

The PCM signal controls the coolant temperature sensor at terminal block 1M PCM. If the voltage of the coolant temperature sensor - higher than 4.6 V, the PCM determines that circuit coolant temperature sensor has a fault.

Exceeded time to fuel control in a closed loop (P0125)

The PCM signal controls the coolant temperature sensor to the PCM output 1M after starting the engine until the engine is warm. If the engine coolant temperature reaches an expected for a period of time set by the instruction, the PCM determines that the output time (on the engine coolant temperature) for controlling the supply of fuel in a closed circuit is exceeded.
