Why is my exhaust back pressure sensor not working?
The exhaust back pressure sensor is faulty. The exhaust back pressure sensor harness is shorted or completely open. There is a poor electrical connection with the exhaust back pressure sensor circuit. The tube that runs from the pressure sensor to the exhaust manifold is blocked.
What causes an exhaust back pressure sensor error code of p0472?
The P0472 error code can be caused by a fault with the exhaust back pressure sensor, the exhaust back pressure sensor harness or when there is an inadequate electrical connection in the exhaust back pressure sensor circuit.
What is the diagnostic code for exhaust pressure sensor malfunction?
P0470 is a diagnostic trouble code (DTC) for “Exhaust Pressure Sensor Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $0.0.
What are the error codes for the DPF sensor?
Just wondered if A) Anyone has had the following error codes: 245400 Minimum differential pressure undershot 25C800 Exhaust back pressure sesnor upstream of DPF, Sensor drift out B ) Changed either of these sensors in the engine bay?
What does it mean when exhaust pressure sensor comes back?
If they do come back, then that means there’s an actual problem. Then they proceed by checking the exhaust back pressure sensor. They disconnect the tube that connects the exhaust manifold to the exhaust pressure sensor and try to run air through it.

What are the symptoms of a bad exhaust pressure control?
Symptoms of a Bad or Failing Exhaust Pressure Control Valve Common signs include engine performance issues, excessive smoke or soot from the exhaust, and the Check Engine Light coming on. by Ed Ruelas on January 08, 2016 1.
