Dr11 - Speed Sensor System Test

Disconnect speed sensor connector. Put system into "Test Mode 96" readout box display should be "02". If readout box display reads "02', proceed to step 2). If display is not "02", replace computer.

Connect a jumper lead between terminals of speed sensor connectors on engine harness. Readout box display should change from "02" to "01". If display changes from "02" to "-1", proceed to step 3) If display changes from "02" to "01", proceed to step 3), if display should not change, proceed to step 6.

Turn ignition off. Remove speed sensor from transaxle. Connect ohmmeter between speed sensor connector terminate. Slowly rotate speed sensor one turn. Ohmmeter should show 8 pulses for every turn of speed sensor. If ohmmeter readings if okay, inspect transaxle drive gear and speed sensor drive gear for proper contact. If ohmmeter reading is not okay, replace speed sensor.

Connect a jumper lead to White/Orange wire of speed sensor harness connector and ground. Readout box display should change from "O2" to "O1". If display changes, repair Black/Blue wire of speed sensor harness connector for an open circuit. If display does not change, repair White/Orange wire of speed sensor connector for an open circuit.
