DESCRIPTION
●PNP switch
The PNP switch assembly includes a transmission position switch. The transmission position switch
detects the selector lever position and sends a signal to the TCM.
●Overdrive control switch

TROUBLE DIAGNOSES FOR SYMPTOMS
Detects the overdrive control switch position (ON or OFF) and sends a signal to the TCM.
●Throttle position sensor*
*: This sensor means accelerator pedal position (APP) sensor.
Electric throttle control actuator consists of throttle control motor, acceleration pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the TCM.
DIAGNOSTIC PROCEDURE
1. CHECK PNP 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 “P/N”, “R”, “D”, “2” and “1” position switches moving selector lever to each position.
Check that the signal of the selector lever position is indicated
properly.
OK or NG
OK >> GO TO 3
NG >> Check the following items:
●PNP switch (Refer to AT- 2 4 2 , "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)

(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
NG >> Check the following items:
●Overdrive control switch (Refer to AT- 2 4 2 , "COMPO-
NENT INSPECTION" .)
