DTC P0793 INTERMEDIATE SHAFT SPEED SENSOR
ºAº
CIRCUIT DESCRIPTION
This sensor detects the rotation speed of the counter gear. By comparing the counter gear speed signal (NC)
with the direct clutch speed sensor signal (NT), the ECM detects the shift timing of the gears and appropriate-
ly controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear shift-
ing is performed.
DTC No.DTC Detection ConditionTrouble Area
P0793
ECM detects conditions (a), (b) and (c) continuity for 5 sec. or
more: (1-trip detection logic)
(a) Vehicle speed: 50 km/h (31 mph) or more
(b) Park/neutral position switch (NSW) is OFF
(c) Speed sensor (NC): less than 300 rpmOpen or short in transmission revolution sensor NC (speed
sensor NC) circuit

Reference (Using an oscilloscope):
Check the waveform between the terminals NC+ and
NC- of the ECM connector.
Standard: Refer to the illustration.
TerminalNC+ - NC-
Tool setting1V/DIV, 1ms/DIV
Vehicle conditionVehicle speed 30 km/h (19 mph): (3rd gear)
Engine speed 1,400 rpm
MONITOR DESCRIPTION
The NC terminal of ECM detects a revolution signal from the speed sensor (NC) (counter gear rpm). The
ECM calculates a gearshift comparing the speed sensor (NT) with the speed sensor (NC).
While the vehicle is operating in 2nd, 3rd or O/D gear in the shift position of D, if the counter gear revolution
is less than 300 rpm
*1 although the output shaft revolution is more than 1,000 rpm*2, the ECM detects the
trouble, illuminates the MIL and stores the DTC.
*1: Pulse is not output or is irregularly output.
*2: The vehicle speed is 50 km/h (31 mph) or more.
