DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position switch and the wire harness in the park/
neutral position switch circuit.
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 shift lever is in the P or N position
The park/neutral position switch sends a signal to the ECM according to the shift position (P, R, N or D).
The ECM determines that there is a problem with the switch or related parts if in receives more than 1
position signal simultaneously. The ECM will turn on the MIL and store the DTC.

DESCRIPTION
The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a
resistance value which is input into the ECM.
The ECM applies a voltage to the temperature sensor through ECM terminal THO1.
The sensor resistance changes with the transmission fluid temperature. As the temperature becomes
higher, the sensor resistance decreases.
One terminal of the sensor is grounded so that the sensor resistance decreases and the voltage goes
down as the temperature becomes higher.
The ECM calculates the fluid temperature based on the voltage signal.
