Operation	Wheel speed sensor is a kind of a pulse generator. It consists of encoders (a plate on which north and south pole sides of the magnets are arranged alternately) for detecting the wheel speed which rotates at the same speed of the wheels and wheel speed sensors. This sensor outputs frequency pulse signals in proportion to the wheel speed. The pulse signals, which the wheel speed sensor creates, are sent to ASC-ECU. ASC-ECU uses the frequency of the pulse signals to determine the wheel speed.

C1043 Description

Short technical summary and product information.

The Omega Engineering C1043 is a wheel speed sensor that functions as a pulse generator. It utilizes encoders with alternating magnetic poles to detect the rotational speed of the wheels. The sensor outputs frequency pulse signals, which are transmitted to the ASC-ECU for processing. The ASC-ECU interprets these signals to determine the vehicle's wheel speed.

This sensor is designed to monitor signals from each wheel speed sensor during vehicle operation. If any periodic drop is detected in these signals, the ASC-ECU will trigger a relevant Diagnostic Trouble Code (DTC), specifically C1041 for Front Left, C1042 for Front Right, C1043 for Rear Left, and C1044 for Rear Right wheel speed tone performance. Probable causes for these DTCs include wheel bearing malfunctions, deformation or foreign material on the encoder, or ASC-ECU issues.

The C1043 is RoHS3 compliant, indicating adherence to environmental standards for hazardous substances. Its operation relies on the integrity of the CAN bus lines and proper functioning of the wheel speed detection encoder and wheel bearing.
