NO.11 SHIFT POINT IS HIGH OR LOW [SJ6A-EL]

11

Shift point is high or low

DESCRIPTION

  • Shift point considerably different from automatic shift diagram.

  • Shift delays when accelerating.

  • Shift occurs suddenly when accelerating and engine speed does not increase.

POSSIBLE CAUSE

  • If the transmission does not shift abnormally, there is a malfunction of the input signal to the APP sensor, turbine sensor, or VSS.

  • If the engine speed is high or low, regardless of normal shifting, inspect the tachometer.

  • Verify that the output signals of the APP sensor change linearly.

NOTE:

  • If a tire of a different diameter from the standard tire is installed, the TCM determines that the driving mode is the AAS mode, and may change to a different shift timing from the normal timing.
