ENGINE SPEED SIGNALPFP:24825
DescriptionECS004UC
The engine speed signal is sent from the ECM to the TCM.
CONSULT-II Reference ValueECS00CT2
Remarks: Specification data are reference values.
On Board Diagnosis LogicECS00CT3
DTC Confirmation ProcedureECS00CT4
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.
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
SLCT LVR POSI: D position
3. If the check result is NG, go to AT- 3 8 4 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions for more than 10 seconds.
Selector lever position: D position
Vehicle speed: higher than 10 km/h (6 MPH)
Throttle position: greater than 1.0/8 of the full throttle position
3. Perform self-diagnosis.
Refer to AT- 5 2 , "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT- 3 8 4 , "
Diagnostic Procedure" .

4. Set manual shaft to position P.
5. Remove park/neutral position (PNP) switch.
6. Remove bracket from transaxle case.
7. Remove revolution sensor from transaxle case.
8. Remove O-ring from revolution sensor.
9. Remove oil pan and oil pan gasket.

Do not reuse oil pan bolts.
10. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.

If frictional material is detected, replace radiator after
repair of A/T. Refer to CO-12, "
RADIATOR" .
11. Remove magnets from oil pan.
12. Remove control valve assembly according to the following procedures.
a. Remove snap ring from terminal body.
b. Push terminal body into transaxle case and draw out terminal
cord assembly.
