P0473: Unleashing The Mystery Behind This Automotive Fault Code
When your car’s Engine Control Module (ECM) detects an out-of-range Exhaust Back Pressure (EBP) signal, it triggers the fault code P0473. This means that the EBP signal is either too high or too low. As a result, the engine will ignore the EBP signal and disable the exhaust back pressure operation.
This fault code indicates a problem with the EBP sensor or the wiring connected to it. It is important to address this issue promptly to ensure proper functioning of the exhaust system and prevent any potential damage to the engine.
