Good evening all. Am having a problem with my motor and am hoping someone can help me out. When I start my motor am getting a beeping alarm which will not shut off until I turn the engine off. I disconnected all the sensors there is and the alarm is still coming on. The motor is not over heating and it is filled with oil, I switched the computer and still the alarm. I changed the harness, ignition and buzzer, the alarm still goes off. I don't know What else to do. I even changed the TPS and the alarm still goes off. Can anyone advise me on what to do?
