Circuit Description

WARNING: This page is about a different car, the 2001 Pontiac Grand Prix, 2001 Pontiac Firebird, 2001 Oldsmobile Intrigue, and 2001 Chevrolet Camaro. However, it is still accessible from the selected car via links, so may be relevant.

Speed sensor used on this vehicle is a multiple pole magnetic pickup. This sensor produces an AC signal that EBCM uses frequency from to calculate wheel speed.

NOTE: Camaro and Firebird use a single rear wheel speed sensor with 3.8L engine.

DTC sets when one of the following occurs:

EBCM detects a deviation between left and right rear wheel speeds of greater than 3.75 MPH at a vehicle speed of less than 62 MPH.
EBCM detects a deviation between left and right front wheel speeds of greater than 6.25 MPH at a vehicle speed of less than 62 MPH.
EBCM detects a deviation between left and right rear wheel speeds of greater than 6 percent of vehicle speed at greater than 62 MPH.
EBCM detects a deviation between left and right front wheel speeds of greater than 2.5 MPH plus 6 percent of vehicle speed at greater than 62 MPH.

This DTC will set when EBCM cannot specifically identify which wheel speed sensor is causing malfunction. If EBCM can identify a specific wheel speed sensor causing malfunction, DTC associated with sensor (DTC C0036, DTC C0041, DTC C0046, or DTC C0051) will be set.
