DTC P0725 ENGINE SPEED SIGNAL

PFP:24825

Description

ECS00970

The engine speed signal is sent from the ECM to the TCM.

On Board Diagnosis Logic

ECS00971

Diagnostic trouble code ENGINE SPEED SIG with CONSULT-II or P0725 without CONSULT-II is detected
when TCM does not receive the proper voltage signal from ECM.

Possible Cause

ECS00972

Check harness or connectors. (The sensor circuit is open or shorted.)

Diagnostic Trouble Code (DTC) Confirmation Procedure

ECS00973

CAUTION:

Always drive vehicle at a safe speed.

NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
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
“ENGINE” with CONSULT-II.

2.

Start engine and maintain the following conditions for at least 10 consecutive seconds.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: More than 1.2V
Selector lever: D position

WITH GST

Follow the procedure “With CONSULT-II”.
