This DTC is stored if the engine does not start or continues to crank without starting for certain period of time. This DTC is also stored if the vehicle has run out of fuel. It is necessary to check whether there was enough fuel in the fuel tank before inspection.

Prior to replacing the ECM, use the intelligent tester to read and save each fuel injector compensation code from the original ECM ().

The throttle position sensor is mounted on the diesel throttle body and detects the opening angle of the throttle valve. This sensor is an electronic sensor and uses Hall-effect elements.

A thermistor is built into the Engine Coolant Temperature (ECT) sensor and it changes its resistance value according to the engine coolant temperature.

The structure of the sensor and connection to the ECM is the same as the intake air temperature sensor.

The Intake Air Temperature (IAT) sensor is built into the charge air cooler and senses the IAT. A built-in thermistor in the sensor changes its resistance value according to the intake air temperature. The lower the intake air temperature, the greater the thermistor resistance value. The higher the intake air temperature, the lower the thermistor resistance value (See Fig. 1).

A thermistor is built into the Engine Coolant Temperature (ECT) sensor and it changes its resistance value according to the engine coolant temperature.

The structure of the sensor and connection to the ECM is the same as the intake air temperature sensor.

The intake air temperature sensor is built into the Mass Air Flow (MAF) meter and senses the intake air temperature.

A thermistor built into the sensor changes its resistance value according to the intake air temperature.

The lower the intake air temperature, the greater the thermistor resistance value. The higher the intake air temperature, the lower the thermistor resistance value (See Fig. 1).

Refer to DTC P0105 ().

The manifold absolute pressure sensor detects the intake manifold pressure by using its built-in sensor unit. The ECM determines the basic injection duration and injection advance timing based on the voltage output by the manifold absolute pressure sensor.
