7A-28 AUTOMATIC TRANSMISSION (AW30-40LE) Circuit Description: Vehicle speed information is provided to the TCM by Test Description: The following numbers correspond to the step numbers 1. When the vehicle is running, a speed signal is input from the vehicle speed sensor 2 to the TCM. 2. At this test, the continuity of circuit wiring and the vehicle speed sensor 2 is checked. 4. At this test, the continuity of the vehicle speed sensor 2 is checked.
Diagnostic Aids: An intermittent may be caused by a poor connection,
CODE 11 VEHICLE SPEED SENSOR 2 (OPEN/SHORTED CIRCUIT) Step Action Value(s) Yes No 1 1. Lift the driving wheels. voltmeter between the TCM 26 pin connector Does the voltage vary in the specified value? 0−About 3 V (Vehicle speed 10 −20 km/h) Code 11 is intermittent. If other codes are not stored, refer to “Diagnostic Aids”. Go to Step 2 2 1. Turn the ignition “OFF”. terminal (22) and (23). Is the resistance within the specified value? 560−680 Ω (20 ℃) 610−740 Ω (40℃) Go to Step 3 Go to Step 4 3 1. Replace the TCM with a new one. − Go to Step 5 Go to Step 7 4 1. Disconnect the connector of the vehicle speed sensor 2 on the transmission side. 2. Measure the resistance between the connector on the vehicle speed sensor 2 side Is the resistance within the specified value? 560−680 Ω (20 ℃) 610−740 Ω (40℃) Go to Step 6 Go to Step 5 5 Replace the vehicle speed sensor 2. − Go to Step 7 − 6 Check the wiring harness between TCM and − Go to Step 7 − 7 1. After the repair is complete, use the scan tool to select “DTC”, then “Clear Info” 2. Make a road running test for the vehicle. − Begin the again Go to Step 1 System OK |
