Refer to DTC P0107 ().

This DTC is stored if engine output decreases due to a malfunction in the intake or exhaust system, fuel system or cooling system.

Using the GTS, the conditions present when the DTC was stored can be confirmed by referring to the freeze frame data. Freeze frame data records engine conditions when a malfunction occurs. This information can be useful when troubleshooting.

Refer to DTC P0100 ().

This DTC is stored when the speed of a specific cylinder becomes low and the idle speed becomes unstable. This DTC is also stored if the vehicle runs out of fuel. Be sure to check whether there is enough fuel in the fuel tank before inspection.

The mass air flow meter consists of a platinum hot wire, a temperature sensor and a control circuit installed in a plastic housing. The temperature sensor (located in the intake air by-pass of the housing) detects the intake air temperature.

There is little variation in the output from the mass air flow meter, as the output voltage is converted into a periodic signal which minimizes the effect of wire harness resistance.

This DTC is stored if the engine does not start or continues to crank without starting for a 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.

The fuel pressure sensor mounted on the common rail assembly converts the fuel pressure inside the common rail assembly into an electrical signal and outputs the signal to the ECM. The ECM controls the fuel supply pump assembly in order to maintain the fuel pressure inside the common rail assembly at a target pressure calculated by the ECM. Refer to System Description ().

After starting the engine, this DTC is stored when the engine stops without the engine switch being operated.

Using the GTS, the conditions present when the DTC was stored can be confirmed by referring to the freeze frame data. Freeze frame data records engine conditions when a malfunction occurs. This information can be useful when troubleshooting.

The ECM stores this DTC if the fuel pressure inside the common rail assembly is higher than 250000 kPa (2550 kgf/cm², 36250 psi). This DTC indicates that: 1) the suction control valve may be stuck open, or 2) there may be a short in the suction control valve circuit.

If this DTC is stored, the ECM enters fail-safe mode and limits the engine power. The ECM continues operating in fail-safe mode until the engine switch is turned off.

This DTC will be stored if there is no valve opening confirmation (IJf) signal sent from the injector driver to the ECM despite the ECM commanding the injector driver to open the pressure discharge valve. This DTC refers to an open or short circuit malfunction of the pressure discharge valve circuit, not a malfunction in which a valve is stuck open or closed.
