Either one of the following conditions is met (1 trip detection logic):


  • When the oil pressure sensor output is 0.4 MPa (4.1 kgf/cm2, 58 psi) or more and the target gear ratio is less than 1.0, the actual gear ratio is 2.0 or more for 2 seconds or more.

  • When the oil pressure sensor output is 0.4 MPa (4.1 kgf/cm2, 58 psi) or more and the target gear ratio is 2.0 or more, the actual gear ratio is less than 0.5 for 1.5 seconds or more.

Detection Logic 1 trip detection logic 1 trip detection logic

MONITOR DESCRIPTION

The ECM compares the actual gear ratio with the target gear ratio. When the actual gear ratio and target gear ratio are different, the ECM detects the malfunction, illuminates the MIL* and stores this DTC.

PROCEDURE


  1. CHECK DTC OUTPUT (IN ADDITION TO DTC P28247F)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    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.

      Tech Tips

      If any DTCs other than P28247F are output, perform troubleshooting for those DTCs first.
