Symptom Troubleshooting - Automatic Transaxle (FN4A-EL): NVH Mazda 5 I

NO. 20 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITIONS/RANGES [FN4A-EL]

20Noise occurs at idle when vehicle is stopped in all positions/ranges
DESCRIPTIONTransaxle is noisy in all positions and ranges when the vehicle is idling.
POSSIBLE CAUSEThe malfunction is in the oil pump which causes a high-pitched noise to be emitted from the transaxle at idle. NOTE: If a noise is emitted during shifting only, the malfunction is in the shift solenoid D, E or shift solenoid A, B, 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. (See BASIC INSPECTION [FN4A-EL] ).
