Circuit Description
The content of this article/image reflects the changes identified in TSB-TS11- 01126
DTC P1382 "Wheel Speed Sensor Malfunction" is present but not included in 2005 service information.
The wheel speed sensor is used to detecting the road situation. As the wheel is rotated, the wheel speed sensor produces an AC voltage that increase with wheel speed. The EBCM uses the frequency of the AC signal to calculate wheel speed. The wheel speed sensor is connected to EBCM by a "twisted pair" of wires. Twisting reduces noise susceptibility than may cause a DTC to set. If the wheel speed sensor detects a rough road condition, the ECM misfire detection diagnostic will be de-activated.
Conditions for Setting the DTC
- Vehicle speed is between 5 km/h and 130 km/h.
- No Vehicle Speed Sensor error not set.
- Wheel speed change is less than 2 km/h and vehicle speed change is more than 5 km/h.
Action Taken When the DTC Sets
- The Malfunction Indicator Lamp (MIL) will not illuminate.
- The ECM will record operating conditions at the time the diagnostic fails. The information will be stored in the freeze frame and failure records buffers.
- A history DTC is stored.
Conditions for Clearing the MIL/DTC
- A history DTC will clear after 40 warm-up cycles without a fault.
- DTC(s) can be cleared by using the scan tool.
