What is the error code for exhaust pressure sensor?
That’s not to say you wouldn’t necessarily get this code in a VW or other make though.
What is the code for Mercedes pressure differential sensor?
Code 2078-008: Check Component B28/8 (Pressure differential sensor DPF). Plausibility error with the ignition on. In addition to the check engine light, you will notice that your Mercedes struggles to accelerate. This is because the boost is turned off, and you are driving without the turbo’s help. Also, the ECU restricts maximum RPMs.
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 happens if the DPF sensor is incorrect?
In some cases, incorrect readings can give a misleading representation on DPF state. In most cases, the sensor will stop operating. This will give a ‘check engine’ light and a corresponding code. This usually triggers limp home mode, so you can expect a noticeable loss of power. DPF exhaust pressure sensor is not expensive.

What causes an error code p0471 on an exhaust pressure sensor?
Possible Causes. There are a number of things that could cause Error Code P0471, including the following: Faulty exhaust back pressure sensor. Shorted or open exhaust back pressure sensor. Poor electrical connection with exhaust back pressure sensor circuit.
How to replace the DPF exhaust pressure sensor?
Pull down the DPF sensor to remove hoses and connector. Remove the clamps from the two hoses. Pay attention to the hoses. One is larger than the other. Remove hoses from the DPF sensor. Press both sides to unplug the electrical connector. Install hoses in the same position. Use new hose clamps. Connect the electrical connector.

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.
Where is the exhaust pressure sensor on my car?
Locate the exhaust pressure sensor attached to the engine or the firewall. Pop open the hood of your vehicle so you can access the engine. Look around for a small, black rectangular box that has 2 rubber hoses coming out from the bottom and an electrical connector plugged into one side.
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 does it mean when your tire pressure sensor says fault?
The “Tire Pressure Sensor Fault” message means that there is an issue with one or more of your tire pressure sensors. The error code may tell you that the tires’ air pressure is too low or too high or that one of the tire pressure sensors is defective.
Where is the exhaust back pressure sensor located?
Once you have completed all of these checks, you could try to install a new sensor. To find the exhaust back pressure sensor, look at the engine at the rear left, the sensor is next to the left exhaust gas recirculation positioner. After changing the sensor and before you drive your vehicle, ensure you clear the codes.
