Engine stalls when shifted to D range, or in R position

DESCRIPTION

• Engine stalls when shifting from N or P position to D range or R position at idle.

POSSIBLE CAUSE

• The malfunction is on the engine control side (e.g. electronic controlled throttle system). Otherwise, the malfunction is in the turbine sensor (engine sometimes starts) or the TCC circuit (engine always stalls).

  NOTE:

  • Before following the troubleshooting steps, make sure that the Automatic Transmission On-Board Diagnostic and Automatic Transmission Basic Inspection are conducted. (See BASIC INSPECTION [SJ6A-EL].)
