Inspection Procedure

WARNING: This page is about a different car, the 2005 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor 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 hand-held tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
Turn the ignition switch to the ON position.
Turn on the tester.
Select the item "DIAGNOSIS / ENHANCED OBD II / DATA LIST".
According to the display on the tester, read the "DATA LIST".

HINT:

SPD (NT) is always 0 while driving:
Open or short in the sensor or circuit.
SPD (NT) is always more than 0 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 installation.
  Standard:
  
  The installation bolt is tightened properly and there is no clearance between the sensor and transaxle case.

1. NG: REPLACE SPEED SENSOR(NT)
2. OK: Go to next step.

INSPECT SPEED SENSOR(NT)

Disconnect the speed sensor connector from the transmission.

Measure the resistance according to the value(s) in the table below.

Standard:

TESTER CONNECTION SPECIFIED CONDITION (1 OF 2)

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

NG: REPLACE SPEED SENSOR(NT)
OK: Go to next step.

CHECK HARNESS AND CONNECTOR(SPEED SENSOR - ECM)

Connect the speed sensor connector.
Disconnect the ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard:

TESTER CONNECTION SPECIFIED CONDITION (2 OF 2)

Tester Connection	Specified Condition 20°C (68°F)
E5 - 35 (NT+) - E5 - 27 (NT-)	560 to 680 Ω

Measure the resistance according to the value(s) in the table below.

Standard (Check for short):

TESTER CONNECTION SPECIFIED CONDITION (CHECK FOR SHORT)

Tester Connection	Specified Condition
E5 - 35 (NT+) - Body ground	10 kΩ or higher
E5 - 27 (NT-) - Body ground	urarr

NG: REPAIR OR REPLACE HARNESS OR CONNECTOR (SEE ELECTRONIC CIRCUIT INSPECTION PROCEDURE )
OK: GO TO NEXT STEP
REPLACE ECM (1GR-FE)
