DTC P0500 Vehicle Speed Sensor Malfunction
DTC P0503 Vehicle Speed Sensor Circuit Malfunction
DESCRIPTION
The cruise control system uses the same vehicle speed signal that is sent to the ECM for the SFI system.
If DTC P0500 is detected, perform the diagnosis using the inspection procedure for DTC P0500 in the SFI system. The speed signal is converted for use by the cruise control inside the ECM.
Both the SFI system and the cruise control system can set DTC P0500, however the detection conditions of the two systems are different.

DESCRIPTION
Shifting from 1st to 5th is performed in combination with "ON" and "OFF"
operation of the shift solenoid
valves SL1, SL2, SL3, S4 and SR which are controlled by the ECM. If an open or
short circuit occurs in
either of the shift solenoid valves, the ECM cont ...
Installation
1. INSTALL THROTTLE BODY
(a) Install a new throttle body gasket to the intake air
surge tank.
(b) Install the throttle body with the 4 bolts.
Torque: 10 N*m (102 kgf*cm, 7 ft.*lbf)
(c) Connect the 2 water by-pass hoses.
(d) Connect the throttle body connector and clamp.
2. INSTA ...
Check for short circuit
(a) If the wire harness is ground shorted (Fig. 5), locate the section by
conducting a resistance check with the body ground (below).
(b) Check the resistance with the body ground.
(1) Disconnect connectors A and C and measure
the resistance.
Standard resistance (Fig. 6)
