DTC SUMMARY

MALFUNCTION DESCRIPTION


The hybrid vehicle control ECU assembly 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 assembly 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 assembly. 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 assembly determines the current accelerator pedal position and controls the hybrid control system based on signals received by terminals VPA and VPA2.

Measure the voltage according to the value(s) in the table below.

Standard Voltage:
Tester Connection Condition Specified Condition
A31-38 (VCPA) - Body ground Power switch on (IG) Below 1 V
A31-37 (EPA) - Body ground Power switch on (IG) Below 1 V
A31-26 (VCP2) - Body ground Power switch on (IG) Below 1 V
A31-25 (EPA2) - Body ground Power switch on (IG) Below 1 V


NOTICE:

Turning the power switch on (IG) with the hybrid vehicle control ECU assembly connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.



e.

Turn the power switch off.


f.

Measure the resistance according to the value(s) in the table below.

Standard Resistance (Check for Open):
Tester Connection Condition Specified Condition
A31-38 (VCPA) - A65-4 (VCPA) Power switch off Below 1 Ω
A31-37 (EPA) - A65-5 (EPA) Power switch off Below 1 Ω
A31-26 (VCP2) - A65-1 (VCP2) Power switch off Below 1 Ω
A31-25 (EPA2) - A65-2 (EPA2) Power switch off Below 1 Ω


Standard Resistance (Check for Short):
Tester Connection Condition Specified Condition
A31-38 (VCPA) or A65-4 (VCPA) - Body ground and other terminals Power switch off 10 kΩ or higher
A31-37 (EPA) or A65-5 (EPA) - Body ground and other terminals Power switch off 10 kΩ or higher
A31-26 (VCP2) or A65-1 (VCP2) - Body ground and other terminals Power switch off 10 kΩ or higher
A31-25 (EPA2) or A65-2 (EPA2) - Body ground and other terminals Power switch off 10 kΩ or higher



g.
