DTC P0500 (Flash Code 25) Vehicle Speed Sensor (RZ4E-TC)

1. DTC P0500 description

Models with ABS

The vehicle speed signal is calculated based on the wheel speed sensor signal and is output to the ECM by the EHCU. If the ECM detects that vehicle speed signals from the EHCU have not been generated for a predetermined period of time, the DTC is set.

Models without ABS

The vehicle speed sensor is used by the ECM and speedometer, and it generates speed signals from the transmission output shaft rotational speed. The sensor has the following circuits.

  • Ignition power supply circuit
  • Ground circuit
  • Vehicle speed sensor signal circuit

The vehicle speed sensor uses Hall elements. They interact with magnetic fields generated by rotating magnets, and output pulse signals. The ECM uses the vehicle speed sensor to calculate the vehicle speed. If the ECM detects that vehicle speed sensor signals have not been generated for a predetermined period of time, the DTC is set.

2. Condition for setting DTC P0500

Condition for running the DTC

  • The battery voltage is 9 to 16 V.
  • The ignition voltage is 9 to 16 V.

Refer to "51.Engine Control 1A.Troubleshooting(RZ4E-TC) DTC P0219 (Flash Code 543) Engine Overspeed Condition".

Condition for setting the DTC

  • The ECM detects that no vehicle speed signal pulse has been generated for 5.1 seconds.

3. Action taken when DTC P0500 sets

  • Euro4: The ECM illuminates the MIL. Refer to Action taken when DTC sets - Type A (Euro4).
  • Except Euro4: The ECM illuminates the check engine warning light. Refer to Action taken when DTC sets - Type A (Except Euro4).

Refer to "51.Engine Control 1A.Troubleshooting(RZ4E-TC) DTC type definitions".

  • The ECM assumes a default vehicle speed value.
  • The ECM limits the fuel rail pressure.
  • The ECM inhibits the cruise control.

4. Condition for clearing DTC P0500

  • Euro4: Refer to Condition for clearing the MIL/DTC - Type A or Type B (Euro4).
  • Except Euro4: Refer to Condition for clearing the check engine warning light/DTC - Type A or Type B (Except Euro4).

Refer to "51.Engine Control 1A.Troubleshooting(RZ4E-TC) DTC type definitions".
