Circuit description

WARNING: This page is about a different variant/trim than selected.

The transmission control computer ASSY detects the gear position based on signals from the transmission revolution sensor (NT) and the transmission revolution sensor (SP2). Then, the transmission control computer ASSY detects mechanical problems of related solenoid valve, valve body, or automatic transmission when the detected gear position differs from the commanded position.

 Inspection parts
P0751
  1. Driving in D position with ATF temperature at 20°C or higher and the coolant temperature at 40°C or higher (however, no malfunction is detected in transmission 3 way solenoid ASSY (S1, S2, S3, S4, SR), clutch control solenoid No. 1 (SL1, SL2), line pressure control solenoid ASSY (SLT), transmission revolution sensor (NT, SP2), neutral start switch, CAN bus, engine ECM communication, engine coolant temperature sensor, air flow sensor, electronic throttle control, and accelerator pedal sensor).
  2. All of the following conditions are established. When the transmission control computer ASSY commands 5th gear, the actual gear is also shifted to 5th position. When the transmission control computer ASSY commands 6th gear, engine overruns (neutral status).
