CIRCUIT DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
DTC No.DTC Detection ConditionTrouble Area
P0705
(A) Any 2 or more signals of the following are ON simulta-
neously (2−trip detection logic)
SP input signal is ON.
SN input signal is ON.
SR input signal is ON.
SD input signal is ON.
(B) When any of following conditions is met for 2.0 sec. or
more in the S position (2−trip detection logic)
SP input signal is ON.
SN input signal is ON.
SR input signal is ON.

SPark/neutral position switch
SECM
MONITOR DESCRIPTION
The park/neutral position switch detects the shift lever position and sends a signal to the ECM.
For security, the park/neutral position switch detects the shift lever position so that engine can be started
only when the vehicle is in P or N shift position.
When the park/neutral position switch sends more than one signal at a time from switch positions P, R, N
or D, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

DIAGNOSTIC TROUBLE CODE CHART
If a DTC is displayed during the DTC check, check the parts listed in the table below and proceed to the page
given.
HINT:
S *1 : F ... MIL (Malfunction Indicator Lamp) light up
S *2 : ’’ f ’’ mark means ECM memorizes the malfunction code if the ECM detects the DTC detection
condition.
S This DTC may be output when the clutch, brake and gear components etc. inside the automatic trans-
axle are damaged.
DTC No.

FAIL−SAFE CHART
1. FAIL−SAFE
This function minimizes the loss of the ECT functions when any malfunction occurs in each sensor or sole-
noid.
(a) ATF (Automatic Transmission Fluid) temperature sensor:
When the ATF temperature sensor has a malfunction, 5th upshift is prohibited.
(b) Counter gear speed sensor NC (Speed sensor NC):
When the counter gear speed sensor has a malfunction, 5th upshift is prohibited.
(c) Shift solenoid valve DSL:
When the solenoid valve DSL has a malfunction, the current to the solenoid valve is stopped.
This stops lock−up control, then fuel economy decreases.
