3.5 Ecoboost Crankcase Pressure Sensor Location
The crankcase pressure sensor is located in the engine’s crankcase. The 3.5 Ecoboost engine is a powerful and reliable engine that is used in many Ford vehicles.
The engine is designed to deliver excellent performance, but it relies on several sensors to ensure that it operates correctly. One of the most important of these sensors is the crankcase pressure sensor.
In this blog post, we’ll be discussing the 3.5 Ecoboost crankcase pressure sensor location, what symptoms to look out for, and how to replace it if necessary.
Location of the 3.5 Ecoboost Crankcase Pressure Sensor
The crankcase pressure sensor is located in the engine’s crankcase, which is part of the engine that houses the crankshaft. To locate the sensor, you’ll need to look for the PCV (positive crankcase ventilation) valve, which is located near the throttle body. The crankcase pressure sensor is usually mounted directly above or below the PCV valve.
If you’re having trouble finding the sensor, consult your vehicle’s owner’s manual or a repair manual for specific instructions. You can also use an online search engine to find detailed instructions for your specific vehicle.

Symptoms of a Faulty Crankcase Pressure Sensor
A faulty crankcase pressure sensor can cause several problems with your engine. The most common symptoms of a bad sensor include:
Engine warning light
If the sensor is not functioning correctly, it may cause the engine warning light to come on. This light will usually appear as a check engine light and can be diagnosed with a code reader.
Reduced engine performance
A bad crankcase pressure sensor can cause the engine to perform poorly. You may notice a decrease in power and acceleration, and the engine may feel sluggish or hesitate when accelerating.
Increased oil consumption
A bad crankcase pressure sensor can cause an increase in oil consumption, which can lead to decreased engine performance and reduced fuel efficiency.
Replace the 3.5 Ecoboost Crankcase Pressure Sensor
If you suspect that your 3.5 Ecoboost crankcase pressure sensor is faulty, it’s important to replace it as soon as possible to avoid any further damage to your engine. Here are the steps you need to follow to replace the sensor:
Gather the tools and equipment you’ll need
You’ll need a socket set, a wrench, a torque wrench, and a new crankcase pressure sensor.
Locate the sensor
Follow the steps in the “Location of the 3.5 Ecoboost Crankcase Pressure Sensor” section to find the sensor.
Disconnect the electrical connector
The electrical connector is usually located near the sensor and can be disconnected by simply pulling it off.
Remove the old sensor
Use a socket and wrench to remove the old sensor from its mounting bracket. Make sure to keep track of any washers or gaskets that may come off with the sensor.
Install the new sensor Put the new sensor in place, making sure to use any washers or gaskets that were removed from the old sensor. Use a torque wrench to tighten the sensor to the manufacturer’s specified torque specifications.
Connect the electrical connector
Reattach the electrical connector to the new sensor.
Test the engine
Start the engine and check for any warning lights or symptoms of a faulty sensor. If everything is working correctly, the engine should run smoothly.
Safety Precautions
When working on your vehicle’s engine, it’s important to take safety precautions to avoid injury. Here are a few things to keep in mind:
- Always work in a well-lit, well-ventilated area.
- Wear protective gear, such as gloves and safety glasses.
- Make sure the engine is cool before working on it.
- Make sure to follow the manufacturer’s instructions for torque specifications.

3.5 Ecoboost Crankcase Pressure Sensor Part Number
If your 3.5 Ecoboost engine is making a knocking noise, it could be due to a problem with the crankcase pressure sensor. This sensor is located on the side of the engine block and monitors the pressure inside the crankcase. If the pressure gets too high, it can cause damage to the engine internals.
You can check for a faulty crankcase pressure sensor by looking for oil leaks around the sensor or by using a code reader to check for error codes. If you suspect that your sensor is faulty, you should replace it with a new one. The part number for the 3.5 Ecoboost crankcase pressure sensor is BL3Z-6M280-A.
3.5 Ecoboost Crankcase Breather
If you’re looking for a way to improve the performance of your 3.5 Ecoboost engine, one option is to install a crankcase breather. This device helps to release pressure build-up in the engine, which can lead to increased power and efficiency. Here’s what you need to know about choosing and installing a crankcase breather on your 3.5 Ecoboost engine.
There are two main types of crankcase breathers: catch cans and baffles. Catch cans are designed to collect oil mist and other contaminants that can be harmful to your engine. Baffles, on the other hand, allow fresh air into the crankcase while keeping oil mist and other contaminants out.
Both types of devices have their pros and cons, so it’s important to choose the one that’s right for your needs. Installing a crankcase breather is relatively simple, but it’s important to follow directions carefully. First, find a location for the device that won’t interfere with any moving parts in the engine bay.
Next, drill holes for the mounting bolts and attach the unit using provided hardware. Finally, connect any hoses or fittings according to manufacturer instructions. Once installed, be sure to check the level of oil in your engine regularly.
If you notice an increase in oil consumption after installing a crankcase breather, it’s likely due to an improper installation or incorrect fitment.

The 2017 Ford 3.5 Ecoboost Crankcase Pressure Sensor is a critical component of your engine, and it’s important to know how it works and how to troubleshoot it if necessary. The crankcase pressure sensor is located on the side of the engine near the oil filter. It monitors the pressure in the crankcase and sends a signal to the engine computer when it detects a problem.
If the pressure in the crankcase gets too high, it can cause serious problems with your engine.
2015 F150 3.5 Ecoboost Crankcase Pressure Sensor Location
If you have 2015 F150 with a 3.5 Ecoboost engine, you may be wondering where the crankcase pressure sensor is located. Here’s a quick guide to help you find it. The crankcase pressure sensor is located on the driver’s side of the engine, just behind the oil filter housing.
It’s a small sensor, about the size of a dime, with two wires coming out of it. To access the sensor, you’ll need to remove the air intake ductwork that runs from the air filter box to the throttle body. There are four clips that hold this ductwork in place – two at the throttle body end and two at the air filter box end.
Once these are removed, you should be able to pull the ductwork off and get access to the crankcase pressure sensor. Unplugging and replugging this sensor is a simple matter of disconnecting and reconnecting the two wires that go to it. However, if your truck is still under warranty, I’d recommend taking it to a dealer or certified mechanic to have them do this work for you so that you don’t void your warranty.
