AUTOMATIC TRANSAXLE SYSTEM, Diagnostic DTC:P098712

DTC Code DTC Name
P098712 Transmission Fluid Pressure Sensor/Switch "E" Circuit Short to Battery

DESCRIPTION

No. 3 ATF pressure switch is installed in the lock-up solenoid ATF output passage and is used to detect a malfunction in the lock-up solenoid.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Memory Note
P098712 Transmission Fluid Pressure Sensor/Switch "E" Circuit Short to Battery

Both conditions are met (2-trip detection logic):


  • No. 3 ATF pressure switch is on when lock-up does not occur.

  • Lock-up does not occur when shift solenoid valve SLU is commanded to turn off in the lock-up range.

  • Harness and connector

  • Wiring harness connector

  • No. 3 ATF pressure switch (ATF temperature sensor assembly)

  • Transmission wire

  • ECM

 Comes on DTC stored SAE: P0990

MONITOR DESCRIPTION

The ECM illuminates the MIL and stores the DTC if it detects that the ATF pressure switch is OFF with the lock-up solenoid ON or if it detects that the ATF pressure switch is ON with the lock-up solenoid OFF.

PROCEDURE


  1. CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P098712)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Transmission / Trouble Codes.


      Powertrain > Transmission > Trouble Codes

    5. Read the DTCs using the GTS.

      Only DTC P098712 is output A
      P098712 and other DTCs are output B

      Tech Tips

      If a solenoid is stuck OFF, DTCs for several solenoids including the malfunctioning solenoid will be stored.

      Front view of wire harness connector

      (to ECM)

      Disconnect the ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C20-85 (TPS3) - Body ground Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    OK

  3. CHECK HARNESS AND CONNECTOR (WIRING HARNESS CONNECTOR - ECM)


    1. Disconnect the C21 wiring harness connector.

    2. Disconnect the C20 ECM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      C21-10 (TPS3) or C20-85 (TPS3) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR
