  • The symptoms of the automobile fault code P0472 include: – Malfunction indicator lamp (MIL) illuminated – Decreased engine performance – Increased fuel consumption – Exhaust system noise – Possible black smoke from the exhaust – Possible difficulty starting the engine – Possible engine misfire or hesitation

The automobile fault code p0472 can be caused by a faulty exhaust back pressure sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit.

  • The fault code P0472 can be caused by a faulty Exhaust Back Pressure Sensor, an open or shorted harness for the Exhaust Back Pressure Sensor, or a poor electrical connection in the Exhaust Back Pressure Sensor circuit.

To fix the p0472 fault code, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code P0472, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the code.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of the automobile fault code p0472 are the estimated repair time of 1.0 hour and the hourly rate charged by auto repair shops, which typically ranges between $75 and $150.

When your car’s Engine Control Module (ECM) detects an out-of-range Exhaust Back Pressure (EBP) signal, it triggers the fault code P0472. 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.
