Emergency driving situations usually lead to someone slamming on their brakes to stop abruptly. The anti-lock brake system (ABS) helps to prevent wheel lockage in such situations so that your 2001 to 2006 Honda Accord doesn't skid. In order for the ABS to function properly, the wheel speed sensors, which send signals regarding the speed of each wheel to the ABS, must be operating.
Park your Honda Accord on a level surface, make sure the ignition is off, activate the emergency brake and place blocks behind the back tires for safety. Disconnect the negative battery cable with a terminal puller.
Raise the vehicle on the side of the wheel speed sensor's location. Remove the wheel and tire assemblies.
Disconnect the sensor harness connector. At the connector end, remove the grommets, clips or retainers in order to detach the harness. Take note of where these connect in order to install the new sensor correctly.
Unscrew the speed sensor mounting bolt and remove the sensor from the vehicle.
Obtain the new speed sensor and install it in the differential housing, with the retaining bolt loosely tightened.
Use the white line on the wires as a guide and route the wiring harness without twists or crimps. Then torque the mounting bolt to 7.2 foot pounds (9.8 Nm).
Start at the sensor end and, working your way to the connector end, attach all the clips, retainers and grommets as observed during removal. Connect the sensor wire.
Lower the vehicle safely and reconnect the negative battery cable. Refer to your owner's manual to perform an ABS system check to confirm that you installed the sensor properly.
