VEHICLE SPEED SENSOR - A/T (REVOLUTION SENSOR)
Diagnostic Procedure
ECS007RP
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
OK or NG
OK >> GO TO 3
NG >> Repair or replace damaged parts.

DTC VEHICLE SPEED SENSOR MTR
DTC VEHICLE SPEED SENSOR MTR
PFP:24814
DescriptionECS007RQ
The vehicle speed sensor·MTR is built into the speedometer assembly. The sensor functions as an auxiliary
device to the revolution sensor when it is malfunctioning. The TCM will then use a signal sent from the vehicle
speed sensor·MTR.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.

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 and vehicle speed higher than 20
km/h (12 MPH).
4. If DTC is detected, go to AT- 3 5 1 , "
