DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input)DESCRIPTION
DTC Detection Condition:
The park/neutral position switch detects the shift lever position and sends signals to the ECM.

Typical Malfunction Thresholds (Part 2):
Component Operating Range:
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, D, or S). The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The ECM will turn on the MIL and store the DTC.

INSPECTION PROCEDURE
1. DATA LIST
HINT: Using the intelligent tester or Techstream to read the Data List allows the values or states of switches, sensor, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may by discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
NOTE: In the table, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
a. Warm up the engine.
b. Turn the engine switch off.
c. Connect the intelligent tester or Techstream to the DLC3.
d. Turn the engine switch on (IG).
e. Turn the tester ON.
f. Enter the following menus:
1. Intelligent tester - Select: DIAGNOSIS / ENHANCED OBD II / DATA LIST / USER DATA.
2. Techstream - Select: Powertrain / Engine / Data List / All Data.
g. According to the display on the tester.
