PNP Switch
1. Check continuity between terminals 1 and 3 and between termi-
nals 2 and 4, 5, 6, 7, 8, 9 while moving manual shaft through
each position.
2. If NG, check again with manual control cable disconnected from
manual shaft of A/T assembly. Refer to step 1.
3. If OK on step 2, adjust manual control cable. Refer toAT-456,
"Control Cable Adjustment".
4. If NG on step 2, remove PNP switch from A/T and check conti-
nuity of PNP switch terminals. Refer to step 1.
5. If OK on step 4, adjust PNP switch. Refer toAT- 4 5 6 , "

VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)
PFP:32702
DescriptionECS004TJ
The revolution sensor detects the revolution of the idler gear parking
pawl lock gear and emits a pulse signal. The pulse signal is sent to
the TCM which converts it into vehicle speed.

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 30 km/h
(19 MPH), throttle opening greater than 1/8 of the full throttle
position and driving for more than 5 seconds.
Without CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 30 km/h
(19 MPH), throttle opening greater than 1/8 of the full throttle
position and driving for more than 5 seconds.
