2UR-GSE ENGINE CONTROL: SFI SYSTEM: P0705: Transmission Range Sensor Circuit Malfunction (PRNDL Input)
P0705 - Transmission Range Sensor Circuit Malfunction (PRNDL Input)
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 P or N.
The park/neutral position switch sends a signal to the ECM according to the shift position (P, R, N, D, or M). 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.

CONFIRMATION DRIVING PATTERN
1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
4. Turn the engine switch off and wait for at least 30 seconds.
5. Turn the engine switch on (IG) and turn the Techstream on.
6. Move the shift lever to R and wait 2 seconds or more.
7. Move the shift lever to N and wait 2 seconds or more.
8. Move the shift lever to D and wait 2 seconds or more.
9. Move the shift lever to M and wait 2 seconds or more.
10. Move the shift lever to P and wait 2 seconds or more.
11. Wait 1 minute or more.
12. Enter the following menus: Powertrain / Engine / Trouble Codes.
13. Read the pending DTCs.
HINT
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
14. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
15. Input the DTC: P0705.
16. Check the DTC judgment result.
HINT
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
17. If the test result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE
HINT
Using the 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.
1. DATA LIST
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.
(a) Warm up the engine.
(b) Turn the engine switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the engine switch on (IG).
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine / Data List / All Data.
(g) According to the display on the Techstream.
PROCEDURE
1. READ VALUE USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List.
(e) According to the display on the Techstream.
OK:
NG -- CHECK HARNESS AND CONNECTOR (BATTERY - PARK/NEUTRAL POSITION SWITCH)
OK -- Continue to next step.
2. READ VALUE USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List / Sports Mode Selection SW.
(e) According to the display on the Techstream.
OK:
NG -- INSPECT TRANSMISSION CONTROL SWITCH
OK -- CHECK FOR INTERMITTENT PROBLEMS Check for Intermittent Problems
3. INSPECT TRANSMISSION CONTROL SWITCH
(a) Inspect the transmission control switch Transmission Control Switch.
NG -- REPLACE TRANSMISSION CONTROL SWITCH Removal
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (ECM - TRANSMISSION CONTROL SWITCH)
(a) Disconnect the ECM connector.
(b) Turn the engine switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
HINT
*: The voltage will drop slightly due to the turning on of the back up light.
(d) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - TRANSMISSION CONTROL SWITCH)
OK -- REPLACE ECM Removal
5. CHECK HARNESS AND CONNECTOR (BATTERY - PARK/NEUTRAL POSITION SWITCH)
(a) Disconnect the park/neutral position switch connector.
(b) Turn the engine switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
(d) Reconnect the park/neutral position switch connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BATTERY - PARK/NEUTRAL POSITION SWITCH)
OK -- Continue to next step.
6. INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
(a) Inspect the park/neutral position switch assembly Component Tests and General Diagnostics.
NG -- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY Removal
OK -- Continue to next step.
7. CHECK HARNESS AND CONNECTOR (ECM - PARK/NEUTRAL POSITION SWITCH)
(a) Turn the engine switch on (IG).
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
(c) Turn the engine switch off.
(d) Disconnect the ECM connector.
(e) Turn the engine switch on (IG).
(f) Measure the voltage according to the value(s) in the table below.
