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
Detects the overdrive control switch position (ON or OFF) and
sends a signal to the TCM.
●Closed throttle position signal and wide-open throttle position
signal
ECM judges throttle opening based on a signal from accelerator
pedal position sensor, and sends the signal via CAN communi-
cation to 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- 3 4 9 , "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)

TROUBLE DIAGNOSES FOR SYMPTOMS
5. CHECK CLOSED THROTTLE POSITION AND WIDE OPEN THROTTLE POSITION SIGNAL 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 “CLOSED THL/SW” and “W/O THRL-SW” depressing and releasing accelerator pedal.
Check the signal of throttle position signal is indicated properly.
OK or NG
OK >> GO TO 7.
NG >> Check the following items. If any items are damaged, repair or replace damaged parts.
●Accelerator pedal position sensor — Refer to AT- 3 6 2 , "ACCELE RATOR PEDAL POSITION
(APP) SENSOR" .
●Harness for short or open between accelerator pedal position sensor and ECM
6. CHECK CLOSED THROTTLE POSITION AND WIDE OPEN THROTTLE POSITION SIGNAL CIRCUIT
(WITHOUT CONSULT-II)
Without CONSULT-II
Check the following items:
●Accelerator pedal position sensor — Refer to AT- 3 6 2 , "ACCELE RATOR PEDAL POSITION (APP) SEN-
SOR" .
●Harness for short or open between accelerator pedal position sensor and ECM
OK or NG
OK >> GO TO 7.
NG >> Repair or replace damaged parts.
7. CHECK DTC
Perform “SELF-DIAGNOSTIC PROCEDURE (WITHOUT CONSULT-II)”. Refer to AT- 2 5 3 , "
SELF-DIAGNOS-
TIC PROCEDURE (WITHOUT CONSULT-II)" .
OK or NG
OK >>INSPECTION END
NG >>
●Perform TCM input/output signal inspection.
●If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

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.
