Inspection Procedure

HINT:

Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.

NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

Warm up the engine.
Turn the ignition switch OFF.
Connect the intelligent tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
Turn the ignition switch ON.
Turn the intelligent tester ON.
Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.

Follow the instructions on the tester and read the DATA LIST.

ITEM MEASUREMENT NORMAL CONDITION CHART

Item	Measurement Item/Range (Display)	Normal Condition	Diagnostic Note
SPD (NT)	Input turbine speed/ Min.: 0 rpm Max.: 12,750 rpm	Lock up ON (after warming up engine): Input turbine speed (NT) is equal to engine speed Lock up OFF (idling with shift lever on N): Input turbine speed (NT) is nearly equal to engine speed	Data is displayed in increments of 50 rpm

HINT:

SPD (NT) is always 0 rpm while driving:
Open or short in the sensor or circuit.
SPD (NT) is always more than 0 rpm and less than 300 rpm while driving the vehicle at 50 km/h (31 mph) or more:
Sensor trouble, improper installation, or intermittent connection trouble of the circuit.

INSPECT SPEED SENSOR (INSTALLATION)
1. Check the speed sensor NT installation.
  OK: Installation bolt is tightened properly and there is no clearance between the sensor and transmission case.

NG: SECURELY INSTALL SPEED SENSOR OR REPLACE SPEED SENSOR

OK: Go to Next Step

INSPECT SPEED SENSOR NT

Disconnect the T27 sensor connector from the transmission.

Measure the resistance of the sensor.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Condition	Specified Condition
1 - 2	20°C (68°F)	560 to 680 Ω

NG: SECURELY INSTALL SPEED SENSOR OR REPLACE SPEED SENSOR

OK: Go to Next Step

CHECK WIRE HARNESS (SPEED SENSOR - ECM)

Measure the resistance of the wire harness side connector.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION

Tester Connection	Specified Condition
E3-21 (NT+) - E3-20 (NT-)	560 to 680 Ω
E3-21 (NT+) - Body ground	10 kΩ or higher
E3-20 (NT-) - Body ground	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: REPLACE ECM
