DTC P0500: Vehicle Speed Sensor <M/T>

CIRCUIT OPERATION
• A 5-volt voltage is applied to the vehicle speed sensor output terminal (terminal No. 3) from the ECM (terminal No. 86). The vehicle speed sensor generates a pulse signal when the output terminal is opened and grounded.
TECHNICAL DESCRIPTION
• The vehicle speed sensor converts the vehicle speed into pulse signals and inputs them to the ECM.
• The vehicle speed sensor outputs a pulse signal while the vehicle is driven.
• The ECM checks whether the pulse signal is output.
DESCRIPTIONS OF MONITOR METHODS
• If the vehicle speed sensor output does not change while the vehicle is being driven in the medium- to high-speed range, a malfunction is determined to have occurred.
MONITOR EXECUTION

DTC SET CONDITIONS Logic Flow Chart


Check Conditions
Two seconds or more have passed the starting sequence was completed.
Engine speed is at between 2,000 and 4,000 r/min.
Volumetric efficiency is at between 45 and 100 percent.

Judgement Criteria
• Vehicle speed sensor output voltage has not changed (no pulse signal is input) for 2 seconds.
OBD-II DRIVE CYCLE PATTERN
None.
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:
• Vehicle speed sensor failed.
• Open or shorted vehicle speed sensor circuit, or connector damage.
• ECM failed.
