DTC P0705: Transmission Range Sensor Circuit Malfunction (PRNDL Input): Procedure
WARNING: This page is about a different car, the 2011 Toyota Matrix. However, it is still accessible from the selected car via links, so may be relevant.
- CHECK HARNESS AND CONNECTOR (BATTERY - PARK/NEUTRAL POSITION SWITCH)
- Disconnect the park/neutral position switch connector.
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard voltage
Tester Connection Switch Condition Specified Condition B13-2 (RB) - Body ground Ignition switch ON 11 to 14 V
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (OUTPUT SIGNAL)
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard voltage
Tester Connection Switch Condition Specified Condition B13-4 (B) - Body ground Ignition switch ON 11 to 14 V
NG → See step 8
OK: Go to next step
- INSPECT PARK/NEUTRAL POSITION SWITCH ASSEMBLY
- Disconnect the park/neutral position switch connector.
- Measure resistance according to the value(s) in the table below when the shift lever is moved to each position.
Standard resistance
Tester Connection Shift Position Specified Condition 4 - 5 P and N Below 1 Ω Except P and N 10 Ω or higher 2 - 6 P Below 1 Ω Except P 10 Ω or higher 2 - 1 R Below 1 Ω Except R 10 Ω or higher 2 - 9 N Below 1 Ω Except N 10 Ω or higher 2 - 7 D, S, "+" and "-" Below 1 Ω Except D, S, "+" and "-" 10 Ω or higher
NG → See step 9
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ECM)
- Connect the park/neutral position switch connector.
- Disconnect the ECM connector.
- Turn the ignition switch to ON, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.
Standard voltage
Tester Connection Shift Position Specified Condition B29-73 (P) - Body ground P 11 to 14 V Except P Below 1 V B29-54 (N) - Body ground N 11 to 14 V Except N Below 1 V B29-53 (R) - Body ground R 11 to 14 V * Except R Below 1 V B29-56 (D) - Body ground D and S 11 to 14 V Except D and S Below 1 V HINT:
*: The voltage will drop slightly due to the turning on of the back up light.
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (BATTERY - TRANSMISSION CONTROL SWITCH)
- Disconnect the transmission control switch connector of shift lock control unit assembly.
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard voltage
Tester Connection Switch Condition Specified Condition E39-6 - Body ground Ignition switch ON 11 to 14 V
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK: Go to next step
- INSPECT SHIFT LOCK CONTROL UNIT (TRANSMISSION CONTROL SWITCH)
- Disconnect the transmission control switch connector of shift lock control unit assembly.
- Measure the resistance according to the value(s) in the table below when the shift lever is moved to each position.
Standard resistance
Tester Connection Shift Position Specified Condition E39-6 - E39-13 S, "+" and "-" Below 1 Ω Except S, "+" and "-" 10 Ω or higher
NG → See step 10
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)
- Connect the park/neutral position switch connector.
- Disconnect the ECM connector.
- Turn the ignition switch to ON, and measure the voltage according to the value(s) in the table below when the shift lever is moved to each position.
Standard voltage
Tester Connection Shift Position Specified Condition B29-74 (S) - Body ground S, "+" and "-" 11 to 14 V Except S, "+" and "-" Below 1 V
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 11
- CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH - ECM)
- Turn the ignition switch off.
- Disconnect the ECM connector.
- Disconnect the park/neutral position switch connector.
- Measure the resistance according to the value(s) in the table below.

Standard resistance (Check for open)
Tester Connection Condition Specified Condition B13-4 (B) - B29-52 (NSW) Always Below 1 Ω Standard resistance (Check for short)
Tester Connection Condition Specified Condition B13-4 (B) or B29-52 (NSW) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
OK → See step 11
- REPLACE PARK/NEUTRAL POSITION SWITCH ASSEMBLY. Refer to REMOVAL
- REPLACE SHIFT LOCK CONTROL UNIT. Refer to DISASSEMBLY
- REPLACE ECM. Refer to REMOVAL
