Shift point is high or low
DESCRIPTION
•  Shift point is considerably different from automatic shift diagram.
•  Shift delays when accelerating.
•  Shift occurs quickly 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 accelerator pedal position sensor, TSS sensor, or OSS sensor (including sensor ground).
•  If the engine speed is high or low, regardless of normal shifting, inspect the tachometer.
•  Verify that the output signal of the accelerator pedal position sensor change linearly.
•  Verify fluid level and conditions.
•  Verify main control operation.
