DTC VEHICLE SPEED SENSOR MTR
DTC VEHICLE SPEED SENSOR MTR
PFP: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.

Diagnostic ProcedureECS004TR
1.CHECK DTC WITH ECM
●Check P code with CONSULT-II “ENGINE”.
Turn ignition switch ON and select “SELF DIAGNOSTIC RESULTS” mode for “ENGINE” with CONSULT-II.
Refer to EC-457, "
Malfunction Indicator (MI)" (QR25DE) or EC-1144, "Malfunction Indicator (MI)" (QR20DE).
OK or NG
OK (With CONSULT-II)>>GO TO 2.
OK (Without CONSULT-II)>>GO TO 3.
NG >> Check throttle position sensor circuit for engine control.
2.CHECK INPUT SIGNAL (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “THRTL POS SEN”.
OK or NG
OK >> GO TO 4.
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit.

3. CHECK INPUT SIGNAL (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 41 and 42 while accelerator pedal is depressed slowly.
(Voltage rises gradually in response to throttle position.)
OK or NG
OK >> GO TO 4.
NG >> Check harness for short or open between ECM and
TCM regarding throttle position sensor circuit.
4. CHECK DTC
Perform Self-diagnosis Code confirmation procedure. Refer to AT- 3 6 3 , "

MATION PROCEDURE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Voltage:
Fully-closed throttle valve :Approximately 0.5V
Fully-open throttle valve :Approximately 4V
