13A-153

Code No. P0500: Vehicle speed sensor system

OPERATION

œ

A power voltage of 5 V is applied to the vehicle 
speed sensor (terminal No. 3) from the engine-
ECU (terminal No. 86).

FUNCTION

œ

The vehicle speed sensor converts the vehicle 
speed to the voltage, and then input it into the 
engine-ECU

TROUBLE JUDGMENT

Check Conditions

œ

2 seconds later after the engine has started up.

œ

Engine speed: 2,000 r/min or more.

œ

Under the high load operation (The volumetric 
efficiency is 40 

-

 75 %).

Judgment Criterion

œ

The sensor output voltage remains unchanged 
(no pulse signal is inputted) for 2 seconds.

PROBABLE CAUSE

œ

Failed Vehicle speed sensor

œ

Open/short circuit in vehicle speed sensor circuit 
or loose connector contact

œ

Failed engine-ECU

DIAGNOSIS PROCEDURE
