DTC VEHICLE SPEED SENSOR MTR

DTC VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionECS004SM
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.
On Board Diagnosis LogicECS00CUR
Possible CauseECS00CUS
Check the following items.

Harness or connector
(The sensor circuit is open or shorted.)

Vehicle speed sensor
DTC Confirmation ProcedureECS00CUT
CAUTION:

Always drive vehicle at a safe speed.

If conducting this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 5 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.

TROUBLE DIAGNOSES FOR SYMPTOMS

O/D OFF Indicator Lamp Does Not Come OnECS004SU
SYMPTOM:
O/D OFF indicator lamp does not come on for about 2 seconds
when turning ignition switch to “ON”.
1. CHECK TCM POWER SOURCE
1. Turn ignition switch to ON. (Do not start engine.)
2. Check voltage between TCM connector terminals 10, 19, 28 and ground.
3. Turn ignition switch to OFF.
4. Check voltage between TCM connector terminal 28 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check the following items:

Harness for short or open between ignition switch and
TCM connector terminals 10, 19 and 28

Refer to AT- 3 9 5 , "Wiring Diagram — AT — MAIN" .
