OK or NG
OK >> GO TO 4
NG >> Check the following items:
●PNP switch (Refer to AT- 3 3 8 , "COMPONENT
INSPECTION" .)
●Harness for short or open between ignition switch and
PNP switch
●Harness for short or open between PNP switch and TCM
●Diode (P, N positions)
3.CHECK OVERDRIVE CONTROL SWITCH CIRCUIT (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 “OVERDRIVE SWITCH”.
Check the signal of the overdrive control switch is indicated properly.
(Overdrive control switch “ON” displayed on CONSULT-II means
overdrive “OFF”.)
OK or NG
OK >> GO TO 5

VEHICLE SPEED SENSOR - A/T (REVOLUTION SENSOR)PFP:32702
DescriptionECS007RN
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.
