OK (With CONSULT-II)©GO TO 2.
OK (Without CONSULT-II)©GO TO 3.
NG©Check ignition signal circuit for engine control. Refer to EC section (IGNITION SIGNAL).
2 CHECK INPUT SIGNAL (With CONSULT-II)
With CONSULT-II
1. Start engine.
2. Select ªECU INPUT SIGNALSº in ªDATA MONITORº mode for ªCVTº with CONSULT-II.
3. Read out the value of ªENGINE SPEEDº.
Check engine speed changes according to throttle position.
OK or NG
OK©GO TO 4.
NG©Check the following items:
IHarness for short or open between TCM and ECM
IResistor and ignition coil
Refer to EC section (IGNITION SIGNAL).
3 CHECK INPUT SIGNAL (Without CONSULT-II)

nector.
DTC P0725 ENGINE SPEED SIGNAL
Diagnostic Procedure
AT-68

DescriptionNCAT0055The torque converter clutch solenoid valve is activated, by the TCM
in response to signals sent from the vehicle speed and throttle
position sensors. Lock-up piston operation will then be controlled.
Lock-up operation, however, is prohibited when CVT fluid tempera-
ture is too low.
When the accelerator pedal is depressed (less than 2/8) in lock-up
condition, the engine speed should not change abruptly. If there is
a big jump in engine speed, there is no lock-up.

the next test.
After the repair, perform the following procedure to confirm the
malfunction is eliminated.
