DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input)
DESCRIPTION
The Park/Neutral Position (PNP) switch detects the shift lever position and sends signals to the ECM.
| DTC Code | DTC Detection Condition | Trouble Area |
| P0705 | When one of the following conditions is met: (A) Any 2 or more of the following signals are ON simultaneously (2 trip detection logic). P input signal N input signal R input signal D input signal NSW input signal R input signal D input signal NSW input signal P input signal N input signal R input signal | Park/neutral position switch Transmission control switch (Lower shift lever assembly) Open or short in park/neutral position switch circuit ECM |
MONITOR DESCRIPTION
This DTC indicates 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 the engine can be started only when the shift lever is in P or N.
The park/neutral position switch sends a signal to the ECM according to the shift lever 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 illuminate the MIL and store the DTC.

INSPECTION PROCEDURE
| DATA LIST |
- HINT:
- Using the intelligent tester to read the Data List allows the values or states of switches, sensors, 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 be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
- NOTICE:
- In the table below, 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.
Warm up the engine.
Turn the engine switch off.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Data List.
According to the display on the intelligent tester, read the Data List.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| Neutral Position SW Signal | PNP switch status/ ON or OFF | Shift lever: In P or N: ON Not in P or N: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW Status (P Range) | PNP switch status/ ON or OFF | Shift lever: In P: ON Not in P: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW Status (R Range) | PNP switch status/ ON or OFF | Shift lever: In R: ON Not in R: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW Status (N Range) | PNP switch status/ ON or OFF | Shift lever: In N: ON Not in N: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Sports Shift Up SW | Sport shift up switch status/ ON or OFF | ON: Shift lever held in "+" (up-shift) OFF: Shift lever not in "+" (up-shift) | - |
| Sports Shift Down SW | Sport shift down switch status/ ON or OFF | ON: Shift lever held in "-" (down-shift) OFF: Shift lever not in "-" (down-shift) | - |
| Sports Mode Selection SW | Sport mode select switch status/ ON or OFF | Shift lever position is: ON: In S, "+" and "-" OFF: Not in S, "+" and "-" | - |
| Shift SW Status (D Range) | PNP switch status/ ON or OFF | Shift lever: In D: ON Not in D: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
