Inspection Procedure

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

Using Techstream'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 Techstream to the DLC3.
Turn the ignition switch ON and turn the tester ON.
Enter the following menus: Powertrain / Engine and ECT / Data List.

Follow the instructions on the tester and read the Data List.

MEASUREMENT ITEM/RANGE AND DIAGNOSTIC NOTE

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
SPD (NC)	Counter gear speed/ Min.: 0 rpm Max.: 12,750 rpm	4th when shift lever is on D (after warming up the engine): Intermediate shaft speed (NC) becomes close to the engine speed	Data is displayed in increments of 50 rpm

HINT:

SPD (NC) is always 0 rpm while driving:
Open or short in the sensor or circuit.
SPD (NC) 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 NC installation.
  OK: Installation bolt is tightened properly and there is no clearance between the sensor and transaxle case.

Measure the resistance of the sensor.

Standard resistance

TESTER CONNECTION AND SPECIFIED CONDITION

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

NG: REPLACE SPEED SENSOR NC

OK: Go to Next Step

CHECK WIRE HARNESS (SPEED SENSOR - ECM)

Disconnect the B30 ECM connector.

Measure the resistance of the wire harness side connector.

Standard resistance

TESTER CONNECTION AND SPECIFIED CONDITION

Tester Connection	Specified Condition
B30-101 (NC+) - B30-102 (NC-)	560 to 680 Ω
B30-101 (NC+) - Body ground	10 kΩ or higher
B30-102 (NC-) - Body ground	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

OK: REPLACE ECM
