DTC SUMMARY

MALFUNCTION DESCRIPTION


The hybrid vehicle control ECU calculates the accelerator pedal opening angle based on the output voltage of the main sensor (VPA) and sub sensor (VPA2) of the accelerator pedal (with sensor) rod assembly. If the output voltage of either the main sensor (VPA) or sub sensor (VPA2) deviates, a malfunction will be detected.

The cause of this malfunction may be one of the following:

·

Accelerator pedal (with sensor) rod assembly malfunction

·

Wire harness or connector malfunction

·

Hybrid vehicle control ECU malfunction



DESCRIPTION

The accelerator pedal position sensor is built into the accelerator pedal (with sensor) rod assembly and detects how much the pedal is depressed. This is a non-contact sensor with Hall elements. There are 2 outputs from the sensor. One is used to detect the accelerator pedal position and the other is used as a confirmation to allow the detection of a malfunction in the sensor itself. Voltage is output from the accelerator pedal position sensor to terminals VPA and VPA2 of the hybrid vehicle control ECU. This voltage varies from 0 to 5 V in accordance with the accelerator pedal position. Terminal VPA2 is primarily used to detect a malfunction in the sensor itself. The hybrid vehicle control ECU determines the current accelerator pedal position and controls the hybrid control system based on signals received by terminals VPA and VPA2.

MONITOR DESCRIPTION

The hybrid vehicle control ECU calculates the differences of the voltage of main accelerator sensor and sub accelerator sensor. If the differences exceed prescribed values, the hybrid vehicle control ECU determines that there is a malfunction in the accelerator sensor circuit. If the hybrid vehicle control ECU detects this malfunction, it will illuminate the MIL and store a DTC.

3.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4.

Turn the ignition switch off and wait for 2 minutes or more.

5.

Turn the ignition switch to ON and turn the GTS on.

6.

Wait for approximately 10 seconds with the ignition switch ON (READY) and shift lever in P, then fully depress and release the accelerator pedal several times.[*1]

HINT:

[*1]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.


7.

Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.

8.

Check the DTC judgment result.

HINT:
·

If the judgment result shows NORMAL, the system is normal.

·

If the judgment result shows ABNORMAL, the system has a malfunction.
