Vehicle Speed SensorzA/T (Revolution
sensor)
DESCRIPTION
The revolution sensor detects the revolution of the out put shaft
parking pawl lock gear and emits a pulse signal. The pulse sig-
nal is sent to the TCM which converts it into vehicle speed.
ON BOARD DIAGNOSIS LOGIC
Diagnostic trouble code Malfunction is detected when ...Check items
(Possible cause)
: VHCL SPEED SENzA/T
TCM does not receive the proper volt-
age signal from the sensor.+Harness or connectors
(The sensor circuit is open or
shorted.)
+Revolution sensor

SELF-DIAGNOSIS CODE CONFIRMATION
PROCEDURE
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
1) Start engine.
2) Select ªSELF-DIAG RESULTSº mode for A/T with
CONSULT-II.
3) Drive vehicle under the following conditions:
Selector lever in ªDº position, vehicle speed higher
than 30 km/h (19 MPH), throttle opening greater than
1/8 of the full throttle position and driving for more than
5 seconds.
