P2765 CLUTCH B SPEED SENSOR

TRANSMISSION: GR6Z30A

P2765

Description


  • The clutch B speed sensor detects the 1st counter gear speed. The clutch B speed sensor converts the 1st counter gear speed into pulse signal and transmits the signal to TCM.
  • TCM calculates the clutch B (a clutch for odd number gears and reverse) speed based on the signal from the clutch B speed sensor.
