U660E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P0791, P0793: Intermediate Shaft Speed Sensor "A"

Circuit

P0793 - Intermediate Shaft Speed Sensor "A"

DESCRIPTION

This sensor detects the rotation speed of the turbine which shows the input speed of transaxle. By comparing the input turbine speed signal (NC)

with the counter gear speed sensor signal (NC), the TCM detects the shift timing of the gears and appropriately controls the engine torque and

hydraulic pressure according to various conditions, thus, providing smooth gear shift.

MONITOR DESCRIPTION

The NT terminal of the TCM detects a revolution signal from the speed sensor (NT) (input RPM). The TCM calculates a gearshift comparing the

speed sensor (NT) with the speed sensor (NC).

While the vehicle is operating in 2nd, 3rd, 4th or 5th gear in the shift position of D, if the input shaft revolution is less than 300 rpm *1although the

output shaft revolution is more than 1,000 rpm *2, the TCM interprets this as a fault, illuminates the MIL and stores the DTC.

*1: Pulse is not output or is irregularly output.

*2: The vehicle speed is 31 mph (50 km/h) or more.
