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 appropriately controls the engine torque and hydraulic pressure according to various conditions. Thus smooth gear shifting is performed.
Reference (Using an oscilloscope): Check the waveform between terminals NC+ and NC- of the ECM connector.
Standard: Refer to the illustration.
MONITOR DESCRIPTION
The NC terminal of the 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, 4th or 5th gear in the shift position of D, if the counter gear revolution is less than 300 rpm *1although 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.

INSPECTION PROCEDURE
HINT: Using the intelligent tester to read the DATA LIST allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the DATA LIST information early in troubleshooting is one way to save diagnostic time.
1. READ DATA LIST
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn on the tester.
(f) Select the item "DIAGNOSIS / ENHANCED OBD II / DATA LIST".
(g) According to the display on the tester, read the "DATA LIST".
HINT:
1 INSPECT SPEED SENSOR INSTALLATION
(a) Check the speed sensor installation.
OK: The installation bolt is tightened properly and there is no clearance between the sensor and transaxle case.
2 INSPECT SPEED SENSOR (NC)
(a) Disconnect the speed sensor connector from the transaxle.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
3 CHECK HARNESS AND CONNECTOR (SPEED SENSOR - ECM)
(a) Connect the speed sensor connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
(d) Measure the resistance according to the value(s) in the table below.
Standard resistance (Check for short)
