NO.20 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITIONS/RANGES [JA5A-EL]

BME050301030256

20 | Noise occurs at idle when vehicle is stopped in all positions/ranges
DESCRIPTION | • Transaxle noisy in all positions and ranges when the vehicle idling.
POSSIBLE CAUSE | • The malfunction is in the pressure solenoid or oil pump which causes a high-pitched noise to be emitted from transaxle at idle.

  Note

  • If a noise is emitted during shifting only, the malfunction is in shift solenoid A, B, or C. If a noise is emitted during shifting at certain gears only or during deceleration only, it is gear noise.
  • Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.
