Most commonly, the P04DB code will come up listed as “No Description Available” if you’re using your Cobb Accessport to read the fault codes. However, with some research, you’ll find that the P04DB fault code actually refers to “Crankcase Ventilation System Disconnected” DTC.
Where is the crankcase pressure sensor on 6.7 Cummins?
The Cummins 5462277 Fuel Rail Pressure Sensor is located on the top of the engine cover and depicted as part number 16 in the exploded view illustration. This pressure sensor is an OEM Cummins part that is backed by the Cummins Warranty.
What happens if you dont change your CCV filter?
If the filter becomes clogged and causes any vacuum leaks, this may cause a decrease in engine performance due to the disturbance in the air-fuel ratio. The vehicle may experience a decrease in power and acceleration, especially at low engine speeds.
How often should you change CCV filter 6.7 Cummins?
The ‘07.5 and newer 6.7-liter engines have a crankcase vent filter that is located on top of the valve cover assembly. The suggested change interval for the CCV is 67,500 miles.
What does P04DB mean? – Related Questions
How much does a CCV filter cost?
The Crankcase Ventilation Filter should be a part of your regular maintenance schedule as it needs to be replaced at the suggested interval in order to ensure proper engine operation. The cost of this Crankcase Ventilation Filter filter is $86.45, but this is economical compared to the price of a new turbocharger.
What is CCV failure?
The CCV valve sucks away the partially-burned gases from the crankcase through the intake manifold and returns them to the engine to be properly burned. However, in a situation when the valve fails, the toxic blow-by would not be extracted from the crankcase, which in turn wreaks havoc inside your BMW’s engine.
How often should you change your CCV filter?
The vehicle maintenance records should be updated to include a reminder to check and change the filter every year or 1500 hours, whichever occurs first.
How often should you change air filter on 6.7 Powerstroke?
Ford Motor Company recommends that you replace this filter every 15,000-30,000 miles, depending on your vehicle model.
How do you reset the CCV filter on a 6.7 Cummins?

- Fully depress the accelerator pedal slowly two times within 10 seconds and hold it to the floor the second time.
How often should you change a crankcase breather?
To keep the crankcase vent filter in good working condition, it should be changed every time you replace your spark plugs. If this is not done, oil sludge will build up in your filter and cause serious problems and damage your engine.
What happens if breather is blocked?
A breather pipe allows an internal combustion engine to vent crankcase pressure out of the engine. When an engine suffers from a clogged breather pipe, the engine overheats and often begins to misfire. Oil consumption increases and the engine seems to have less power.
What happens when a crankcase ventilation system goes bad?
As the PCV valve starts going bad, the performance of your vehicle will get worse. This can be exhibited by a buildup of pressure in the exhaust or the engine could stall out. The bad PCV valve may not close all the way, so oxygen may get into the combustion chamber.
What does a crankcase breather do in diesel engine?
A crankcase ventilation system removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold).
What causes high crankcase pressure in a diesel engine?
Blow-by, also referred to as crankcase pressure, occurs during the combustion process when burned gases leak past the piston rings and into the crankcase. The rotation and speed of the rotating assembly, which also causes windage, contributes to crankcase pressure, as well.
Why does oil come out of crankcase breather?
Breather mechanism is dirty, damaged or defective. Piston ring gaps are aligned. Piston rings are worn. Blown head and pressure is being blown out of the breather.
How do you fix a blowby on a diesel engine?
Engine blowby can be reduced by following 2 steps : Step 1 Simply add FTC Decarbonizer in with the diesel . Step 2 Use Flushing Oil Concentrate when completing an oil change. “To fix engine blow by, FTC Decarbonizer is added to the diesel at each fill, and you literally just drive the engine clean!
Can Blowby cause turbo failure?
Oil suction from a blow by hose
Excessive piston blow by or high internal crankcase pressure can cause oil leakage from turbocharger compressor or turbine seals.
What happens if you don’t fix Blowby?
Issues Blowby Can Cause
Engine blowby can cause a plethora of problems. One of the most common is cracking piston rings and ruining HEUI fuel injectors in early Powerstroke engines. Ignoring this problem could not only cost your fuel injectors, but also it more than likely will foul your turbo, EGR Valves, and DPF.
