DTC P0909 Gate Select Control Error


DESCRIPTION

In the multi-mode manual transaxle system, the transaxle gear is shifted up and down by the TCM using a shift and select actuator. The shift and select actuator assembly consists of two motors (shift motor and select motor), stroke sensors (shift stroke sensor and select stroke sensor) and gears which move the shift and select lever shaft. The select motor moves the shift and select lever shaft in the select direction in accordance with the signal from the TCM.
This DTC is set in accordance with the stroke speed of the shift and select actuator or the difference between the target select position and the actual select position. Therefore, if malfunctions occur in the select stroke sensor or the select motor circuit, the DTCs relating to the sensor or motor circuit open/short (DTC P0905, P0906, P0907 and/or P0910) are set before this DTC is set.

DTC No.

  2. Difference between target select position and actual select position is 0.3 mm (0.0118 in.) or more
  3. Shift and select actuator movement is 122 mm/sec (4.8 in./sec) or less
  1. Select stroke sensor
  2. Shift and select actuator assembly (select motor)
  3. TCM
  4. Shift heads or shift fork shafts*1 (built into transaxle assembly)
УКАЗАНИЕ:

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:
In select stroke sensor or shift and select actuator assembly replacement, perform the [Initialization and Learning] procedure (See page Нажмите здесь) and [Synchronization Position Calibration] procedure (See page Нажмите здесь) after installing the sensor or actuator assembly. If the sensor or actuator is installed without performing [Initialization and Learning] and [Synchronization Position Calibration], it may cause driving performance degradation or system component breakage.
УКАЗАНИЕ:
If the symptom still occurs even after checking the shift heads and shift fork shafts for dirt, wear, and defects and replacing the defective parts, replace the TCM.
1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0909)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester ON.

  1. Select the following menu items: Powertrain / Multi-Mode M/T / DTC.

  1. Read DTCs.

    If DTC P0909 is detected together with DTC P0905, P0906, P0907, and/or P0910 (DTCs related to the select stroke sensor or shift and select actuator motor circuit open/short), troubleshoot those DTCs first.
