DTC 32: Left Front Wheel Speed Sensor Circuit Open Or Shorted To Ground/Battery: Description

Test detects left front wheel speed sensor circuit open or short to ground or battery voltage.

1. Disconnect harness connector from left front wheel speed sensor. Measure resistance between component terminals. If resistance is 920-1220 ohms at 68°F (20°C), go to next step. If resistance is not as specified, replace wheel speed sensor.
2. Measure resistance between ground and terminal No. 2 (Blue/Black wire) on left front wheel speed sensor connector. If resistance measured is infinite, go to next step. If resistance measured is not infinite, replace wheel speed sensor.
3. Turn ignition switch to LOCK position. Disconnect EBCM harness connectors. Turn ignition switch on. Measure voltage between ground, and terminals No. 5 (Blue wire) and No. 16 (Blue/Black wire) on EBCM 24-pin harness connector. If voltage is 1 volt or less for both circuits, go to next step. If voltage is greater than 1 volt for either circuit, repair suspect circuit for short to voltage.
4. Check continuity of circuits between left front wheel speed sensor harness connector and terminals No. 5 (Blue wire) and No. 16 (Blue/Black wire) on EBCM 24-pin harness connector. If continuity exists in both circuits, go to next step. If continuity does not exist in either circuit, repair suspect circuit for open.
5. Check continuity between terminals No. 5 (Blue wire) and No. 16 (Blue/Black wire) on EBCM 24-pin harness connector. If continuity exists, repair short between Blue wire and Blue/Black wire. If continuity does not exist, reconnect all components. Retrieve DTCs. If DTC 32 is reset, replace EBCM.
