P0715 CLUTCH A SPEED SENSOR

TRANSMISSION: GR6Z30A

P0715

Description


  • The clutch A speed sensor detects the 2nd counter gear speed. The clutch A speed sensor converts the 2nd counter gear speed into pulse signal and transmits the signal to TCM.
  • TCM calculates the revolution speed or the clutch A (even gear) based on the signal from the clutch A speed sensor.
