DTC VEHICLE SPEED SENSOR MTRPFP:24814
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.
CONSULT-II Reference ValueECS00CSH
Remarks: Specification data are reference values.
On Board Diagnosis LogicECS00CSA
Possible CauseECS00CSB
Check the following items.

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

Vehicle speed sensor
DTC Confirmation ProcedureECS00CSC
After the repair, perform the following procedure to confirm the malfunction is eliminated.
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 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.
