What is exhaust back pressure sensor?
The Exhaust Gas Pressure Sensor or Exhaust Back Pressure Sensor (EBP) is a key component in the Diesel Particulate Filter (DPF) regeneration process. The DPF traps Particulate Matter (PM) and soot, preventing it from harming the environment.
Where is the exhaust pressure sensor located?
Usually, you’ll find the sensor bolted onto the side or bottom of the engine, or along the firewall in the back of the engine well.
How do you check exhaust back pressure sensor?
Start the engine and take a vacuum reading at idle with the transmission in neutral, then take another reading at 2,500 rpm. The vacuum reading should increase slightly. If the reading decreases, there’s a good chance that the exhaust system is restricted.
Do you need an exhaust back pressure sensor?
When you have smoke coming out of your tailpipe, you have too much fuel and not enough oxygen which means you don’t have enough boost. The EBP sensor is absolutely crucial to the operation of the 6.4 because it helps the computer to determine how much turbo to add or take away in terms of making power.
How much exhaust back pressure is acceptable?
With the engine idling at normal operating temperature, read the gauge to determine the back pressure. The reading should not exceed 1-1/4 PSI. If the reading exceeds 1-1/4 PSI, the vehicle has restricted exhaust.
What is acceptable exhaust back pressure?
1-1/4 PSI
With the engine idling at normal operating temperature, read the gauge to determine the back pressure. The reading should not exceed 1-1/4 PSI. If the reading exceeds 1-1/4 PSI, the vehicle has restricted exhaust.
How important is exhaust back pressure?
In fact, it helps. The right size pipe is large enough to breathe well but small enough to create a high exhaust flow. Steps in the exhaust system also create negative pressure waves that travel back to the cylinder and help empty the cylinder of those gases.
Can exhaust pressure sensor be cleaned?
A DPF pressure sensor is vital to the longevity of the DPF, and if the DPF becomes completely obstructed, the regeneration process will not fix it. It will need to either be removed and professionally cleaned or replaced, both options on average costing thousands of dollars.
