DTC detection condition

Possible causes

P0705 T/M RANGE SENSOR A [Transmission Range Sensor A Circuit (PRNDL Input)] Two or more range signals simultaneously stay ON continuously for 5 seconds under the following diagnosis condition 1 and 2:
  • Diagnosis condition 1 (continued for 5 seconds or more)
  • TCM power supply voltage: More than 11 V
  • Diagnosis condition 2 (continued for 2 seconds or more)
  • Vehicle speed: Less than 3 km/h (2 MPH)
  • Accelerator pedal position: 0.6/8 or less
  • Idle switch: ON
  • Stop lamp switch: ON
  • Harness or connector (Short circuit between transmission range switch and TCM)
  • Transmission range switch

DTC CONFIRMATION PROCEDURE

CAUTION:

Be careful of the driving speed.

1.PREPARATION BEFORE WORK

If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK DTC DETECTION

  1. Start the engine.
  2. Maintain the following conditions.

Accelerator pedal position : 0.0/8

Brake pedal : Depressed

Vehicle speed : 0 km/h (0 MPH)

  1. Shift the selector lever through entire positions from “P” to “L”. (Hold the selector lever at each position for 10 seconds or more.)
  2. Check the first trip DTC.

Is “P0705” detected? YES >> Go to TM-161, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK TCM INPUT SIGNALS

With CONSULT


  1. Turn ignition switch ON.
  2. Select “Data Monitor” in “TRANSMISSION”.
  3. Select “D POSITION SW”, “N POSITION SW”, “R POSITION SW”, “P POSITION SW” and “L POSITION SW”.
  4. Shift selector lever through entire positions from “P” to “L” and check ON/OFF of each monitor item.

Without CONSULT


Without CONSULT


  1. Turn ignition switch OFF.
  2. Disconnect TCM connector.
  3. Turn ignition switch ON.
  4. Shift selector lever from “P” to “L” and check voltage between TCM harness connector terminals and ground.

Is the check result normal?


Is the check result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".

NO-1 [“D POSITION SW” is “ON” when selector is not in “D” position. (Or connector terminal 4 is at power voltage.)]>>GO TO 2.

NO-2 [“N POSITION SW” is “ON” when selector is not in “N” position. (Or connector terminal 5 is at power voltage.)]>>GO TO 4.

NO-3 [“R POSITION SW” is “ON” when selector is not in “R” position. (Or connector terminal 6 is at power voltage.)]>>GO TO 6.

NO-4 [“P POSITION SW” is “ON” when selector is not in “P” position. (Or connector terminal 7 is at power voltage.)]>>GO TO 8.

NO-5 [“L POSITION SW” is “ON” when selector is not in “L” position. (Or connector terminal 2 is at power voltage.)]>>GO TO 10.
