HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P0705-758: Transmission Range Sensor Circuit
P0705-758 - Transmission Range Sensor Circuit

DESCRIPTION

The shift lever position sensor can send 8 different switch signals to the power management control ECU (HV CPU). The power management control ECU (HV CPU) uses the signals to detect the shift lever position (P, R, N, or D). The power management control ECU (HV CPU) also uses this information to determine intended direction of travel (forward or reverse).

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT (HV)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

(d) Check if DTCs are output.

Result:





(e) Turn the power switch off.

B -- GO TO DTC CHART Hybrid Control System
A -- Continue to next step.

2. CHECK SHIFT LEVER POSITION SENSOR

(a) Turn the power switch on (IG).

(b) Measure the voltage according to the value(s) in the table below.

(c) Turn the power switch off.

NG -- CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)
OK -- Continue to next step.

3. CHECK FOR INTERMITTENT PROBLEMS

(a) Check for intermittent problems Check For Intermittent Problems.

NG -- REPAIR OR REPLACE MALFUNCTIONING PARTS, COMPONENT AND AREA

OK -- REPLACE POWER MANAGEMENT CONTROL ECU Components

4. CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)

(a) Disconnect the shift lever position sensor connector.

(b) Turn the power switch on (IG).

(c) Measure the voltage according to the value(s) in the table below.





Standard Voltage:

NOTICE:
Turning the power switch on (IG) with the shift lever position sensor connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

(d) Turn the power switch off.

(e) Connect the shift lever position sensor connector.

NG -- CHECK AND REPAIR POWER SOURCE CIRCUIT
OK -- Continue to next step.

5. INSPECT SHIFT LEVER POSITION SENSOR

(a) Disconnect the shift lever position sensor connector.

(b) Measure the resistance according to the value(s) in the table below.





Standard Resistance:

(c) Connect the shift lever position sensor connector.

NG -- REPLACE SHIFT LEVER POSITION SENSOR

OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR
