My mazda 3s abs speed sensor is not working, would this cause the motor to stay in 3rd gear? like limp mode almost? When i start my car, there is clicking noise where the PCM is located by the inside passenger floor. Then i when i go into drive it automatically goes into 3rd gear and my dash lights (e.g. park, parking brake,oil,check engine, abs ) flicker and even my front head lights go out. Will replacing the abs speed sensor fix this?
