Vehicle moves in N position

DESCRIPTION

• Vehicle creeps in N position.
• Vehicle creeps if brake pedal is not depressed in N position.

POSSIBLE CAUSE

• If the vehicle moves in N position, basically, the malfunction is in the ATX. Since a malfunction in the sensor circuit or output circuit is the cause of the malfunction in the ATX, inspect the sensors, output circuit, and the related harnesses.
1. Clutch burned (Forward clutch)
• Control valve body malfunction
2. Selector lever position disparity (Although the selector indicator shows N position, hydraulic circuit shows D range or R position)
Note
• Before following troubleshooting steps, make sure that Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted. (See BASIC INSPECTION (GENERAL (L.H.D.) SPECS. SPORT AT) [FN4A-EL].)
