VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)PFP:32702
DescriptionECS004TJ
The revolution sensor detects the revolution of the idler gear parking
pawl lock gear and emits a pulse signal. The pulse signal is sent to
the TCM which converts it into vehicle speed.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle under the following conditions:
Selector lever in “D” 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.

Diagnostic Procedure
ECS004TL
1. CHECK INPUT SIGNAL (WITH CONSULT-II)
With CONSULT-II
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “VHCL/S SE·A/T” while driving.
Check the value changes according to driving speed.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. CHECK REVOLUTION SENSOR (WITH CONSULT-II)
With CONSULT-II
1. Start engine.
●Harness for short or open between TCM, ECM and revolution sensor
●Harness for short or open between ignition switch and revolution sensor
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.

DescriptionECS004TM
The vehicle speed sensor·MTR is built into the speedometer assem-
bly. The sensor functions as an auxiliary device to the revolution sen-
sor when it is malfunctioning. The TCM will then use a signal sent
from the vehicle speed sensor·MTR.
