Input/Turbine Speed Sensor 
“A” Circuit

When below diagnosis conditions are met, primary 
speed sensor value is kept less than 150 rpm for 5 
seconds or more
• Diagnosis Conditions
- Selector lever: “D” position
- Vehicle speed: 11 km/h (7 MPH) or more
- Accelerator pedal position: 1.1/8 or more
- Engine speed: 450 rpm or more
- Secondary speed: More than 500 rpm

• Harness or connectors

(Primary speed sensor circuit is 
open or shorted.)

•  Primary speed sensor

When below diagnosis conditions are met, and pri-
mary speed sensor value is 1,000 rpm or more, 
signal input from primary speed sensor is suddenly 
stopped and that status is kept for 0.1 second or 
more
• Diagnosis Conditions
- Selector lever: “D” position
- Vehicle speed: 11 km/h (7 MPH) or more
- Accelerator pedal position: 1.1/8 or more
- Engine speed: 450 rpm or more
