6.7 Cummins Crankcase Pressure Sensor Location

The 6.7 Cummins crankcase pressure sensor is located on the driver’s side of the engine, just above the oil filter housing. The sensor is a small black box with a single wire connector coming out of it. It should be easy to spot since it is usually highlighted in yellow or orange plastic and has “CRANKCASE PRESSURE” written on it in white letters.

Be sure to check your owner’s manual for specific instructions before attempting any work, as this location may vary depending on the model year and other factors.

The 6.7 Cummins crankcase pressure sensor is located on the left side of the engine, just above the oil filter housing. This sensor helps to monitor levels of blow-by gases that escape from around the piston rings, and it also monitors vacuum levels in order to ensure optimal performance. It’s important to keep an eye on this sensor so that you can identify and address any issues with your engine quickly before they become a bigger problem down the road.

Where is the Crankcase Pressure Sensor?

The Crankcase Pressure Sensor is a small part located near the crankcase of an engine. It is responsible for sensing and measuring the amount of pressure within the crankcase, as well as monitoring changes in that pressure. This information helps to ensure proper operation of the engine and can also help determine when maintenance or repairs are needed.

The exact location of a vehicle’s Crankcase Pressure Sensor will vary depending on make and model, but it can usually be found near the oil filter assembly or intake manifold. Its electrical connectors should be easily accessible, allowing technicians to quickly identify where it is located during service visits.

What Causes Crankcase Pressure Cummins?

Crankcase pressure in a Cummins engine is created by the combustion of fuel, air and oil. When these elements mix together, they create gases that must be expelled from the crankcase. This is achieved through vents that open as pressure builds up inside the crankcase, allowing gas to escape.

If these vents become blocked or malfunctioning due to dirt or debris buildup or other problems with the vent system, it can cause excessive crankcase pressure which can lead to accelerated wear on engine components such as piston rings and valve stems. It can also result in reduced fuel efficiency and increased emissions due to improper sealing between cylinders and pistons. To prevent this from occurring regular maintenance should be carried out where applicable such as replacement of ventilation hoses, checking for clogged filters and ensuring all seals are correctly installed so that no gaps exist for unwanted materials to enter into the crank case causing an increase in pressure levels within it.

What Happens If the Ccv Filter is Clogged?

If the CCV filter is clogged, it can cause a variety of problems. The most common issue that arises when this happens is reduced air flow to the engine. This can lead to an increase in exhaust emissions, a decrease in fuel economy and power output, and even engine damage if left unchecked.

Additionally, because there won’t be as much clean air being pulled into the combustion chamber, it will cause fuel deposits to accumulate on various components. This could result in excessive smoke coming from your tail pipe or other parts of your vehicle beginning to malfunction due to lack of proper lubrication caused by those same deposits building up over time.

How Often Do You Change the Ccv Filter on a 6.7 Cummins?

The 6.7 Cummins is known for being a reliable and powerful engine, but like any diesel engine it needs regular maintenance to stay in top shape. One of the most important parts of this maintenance is changing the CCV filter regularly. The manufacturer recommends that you change the CCV filter on your 6.7 Cummins every 15,000 miles or once a year, whichever comes first.

It’s important to follow these guidelines as failure to do so can lead to clogged filters which can cause decreased performance and increased fuel consumption over time due to buildup inside the filter housing. Changing the CCV filter isn’t overly difficult; however, it does require some special tools such as a socket set and screwdriver as well as an oil catch container if you’re working on an older model truck with no factory drain plug installed yet. So remember – don’t forget about your 6.7 Cummins’ CCV filter!

Change it every 15,000 miles or once per year for optimal performance and fuel efficiency!

6.7 Cummins Crankcase Pressure Sensor Delete

A 6.7 Cummins crankcase pressure sensor delete is an aftermarket modification that allows you to remove the factory-installed crankcase pressure sensor on your 6.7 Cummins engine, allowing for greater air flow and improved performance from your vehicle. This modification can be performed relatively easily with basic tools and a few replacement parts such as hoses, gaskets, and fittings. By removing the sensor, it eliminates any potential issues of oil vapor being released into the intake manifold or turbocharger resulting in increased efficiency and power output from your engine.

Cummins 6.7 Crankcase Pressure Spec

The Cummins 6.7 engine is an extremely reliable diesel engine, and one of its key features is the crankcase pressure specification. This requirement states that the maximum allowable crankcase pressure must not exceed 7.5 psi at full load and idle conditions. Too much crankcase pressure can cause oil leaks in the engine, so it’s important to check this regularly to ensure your Cummins 6.7 is running smoothly.

Ccv Filter 6.7 Cummins Location

The CCV (Crankcase Ventilation) Filter 6.7 Cummins is located on the driver’s side of the engine, just below the fuel filter and to the left of the oil fill tube. This filter traps particles from recirculated crankcase vapors that would otherwise enter into your vehicle’s atmosphere. It is important to regularly check this filter for any blockages or build-up as it can cause excessive smoke and reduced performance if not properly maintained.


In conclusion, it is important to know the location of your 6.7 Cummins crankcase pressure sensor in order to effectively monitor and maintain your engine’s performance. With this knowledge, you can be sure that your vehicle will run optimally and reduce the risk of any major problems down the line.
