MULTI-MODE MANUAL TRANSAXLE SYSTEM, Diagnostic DTC:P0919

DTC Code DTC Name
P0919 Gear Shift Position 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 to move the shift and select lever shaft. The shift motor moves the shift and select lever shaft in the shift direction according to the signal from the TCM.

DTC No.

Gear Shift Position Control Error

The TCM detects the following conditions simultaneously for 2.0 seconds:

(1-trip detection logic)

  1. Shift motor current is 32A or more, or -32A or less.

  2. Difference between target shift position and actual shift 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.

MONITOR DESCRIPTION

This DTC is stored in accordance with the stroke speed of the shift and select actuator or the difference between the target shift position and the actual shift position. Therefore, if a malfunction occurs in the shift stroke sensor or the shift motor circuit, DTCs relating to a sensor or motor circuit open/short (DTC P0915, P0916, P0917 and/or P0920) are stored before this DTC is stored.

CAUTION / NOTICE / HINT

Note:

In shift stroke sensor or shift and select actuator assembly replacement, perform the [Initialization and Learning] procedure and [Synchronization Position Calibration] procedure 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.

Tip:

If the symptom still occurs even after checking the following parts for dirt, wear, and defects and replacing the defective parts, replace the TCM.

  • Synchronizer rings

  • Shift forks

  • Hub sleeves
