CIRCUIT INSPECTION
DTC P0500 Vehicle Speed Sensor Malfunction
CIRCUIT DESCRIPTION
The vehicle speed sensor outputs a 4±pulse signal for every revolution of the rotor shaft, which is rotated
by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectan-
gular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the
ECM. The ECM determines the vehicle speed based on the frequency of these pulse signals.

INSPECTION PROCEDURE
1 Check operation of speedometer.
CHECK:
Drive the vehicle and check if the operation of the speedometer in the combination meter is normal.
HINT:
The vehicle speed sensor is operating normally if the speedometer display is normal.
NG Check speedometer circuit.
OK
2 Check for short in harness and connector between terminal SPD of ECM and
body ground.
PREPARATION:
(a) Remove the glove compartment (See page SF±73).
(b) Disconnect the connector from ECM.
CHECK:
Check continuity between terminal SPD of ECM and body
ground.
OK:
No continuity (1 M W or higher)
NG Repair or replace harness or connector.

DTC P0750, P0755 Shift Solenoid A/B Malfunction
(Shift Solenoid Valve No.1/No.2)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor and direct clutch speed sensor to detect the actual
gear position (1st, 2nd, 3rd or O/D gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical
trouble of the shift solenoid valves, valve body or automatic transaxle (clutch, brake or gear etc.)
DTC No.DTC Detecting ConditionTrouble Area
P0750
P0755During normal driving, the gear required by the ECM does not
match the actual gear
(2 trip detection logic)Shift solenoid valve No.1/No.2 is stuck open or closed
Valve body is blocked up or stuck
Automatic transaxle (clutch, brake or gear etc.)
Check the shift solenoid valve No.1 when DTC P0750 is output and check the shift solenoid valve No.2 when
DTC P0755 is output.
INSPECTION PROCEDURE
1 Check shift solenoid valve No.1 or No.2 operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve No.1 or No.2.
CHECK:
(a) Applying 490 kPa (5 kgf/cm2, 71 psi) of compressed air,
check that the solenoid valve does not leak air.
(b) When battery positive voltage is supplied to the shift sole-
noid valve, check that the valve opens.
NG Replace the shift solenoid valve No.1 or No.2.
OK
