L110F HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P0705-757: Transmission Range Sensor Circuit
P0705-757 - Transmission Range Sensor Circuit

SYSTEM DESCRIPTION

The park/neutral position switch can send 8 different switch signals to the hybrid vehicle control ECU. The hybrid vehicle control ECU uses the signals to detect the shift lever position (P, R, N, or D). The hybrid vehicle control ECU also uses this information to determine intended direction of travel (forward or reverse).

INSPECTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (SHIFT SENSOR SW)

(a) Connect the Techstream to the DLC3.

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

(c) Select the following menu items: Powertrain / Hybrid Control / Data List / Shift Sensor SW - P, Shift Sensor SW - R, Shift Sensor SW - N, Shift Sensor SW - D, Shift Sensor SW - RV, Shift Sensor SW - FD, Shift Sensor SW - MJ.

(d) While slowly moving the shift lever from P to D, and then back to the P position, read the data list (Shift Sensor SW) displayed on the Techstream.

HINT
Make sure to move the shift lever slowly.

OK:





(e) Check if DTCs are output.

OK:

DTC P0705-757 is not output.

NG -- CHECK PARK/NEUTRAL POSITION SWITCH
OK -- Continue to next step.

2. CHECK FOR INTERMITTENT PROBLEMS

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

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

OK -- REPLACE HYBRID VEHICLE CONTROL ECU Service and Repair

3. CHECK PARK/NEUTRAL POSITION SWITCH

(a) Turn the power switch off.

(b) Disconnect connector E55 from the hybrid vehicle control ECU.

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





Standard resistance (Check for open):





Standard resistance (Check for open):





NOTICE:
*1: The resistance between terminals E55-1 (+BS) and E55-15 (N) should be between 4.2 and 5.2 kOhms.

NG -- INSPECT PARK/NEUTRAL POSITION SWITCH

OK -- REPLACE HYBRID VEHICLE CONTROL ECU Service and Repair

4. INSPECT PARK/NEUTRAL POSITION SWITCH

(a) Disconnect the park/neutral position switch connector.





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

Standard resistance (Check for open):





Standard resistance (Check for short):





NOTICE:
*1: The resistance between terminals E65-7 (+B) and E65-2 (N) should be between 4.2 and 5.2 kOhms.

NG -- REPLACE PARK/NEUTRAL POSITION SWITCH Components

OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR
