Where's That 5.9 Cummins Camshaft Position Sensor? Let's Find Out!
Hey there, Cummins enthusiasts! Today, we're diving into the world of diesel engines to locate that crucial component, the 5.9 Cummins camshaft position sensor. If you're here, chances are you're experiencing some issues with your engine, or you're just curious about your truck's inner workings. Either way, we've got you covered! Guys, explore more in Guides And Explainers and 5.9 cummins camshaft position sensor location.
Why the Camshaft Position Sensor Matters
Before we get our hands dirty, let's talk about why the camshaft position sensor (CMP) is so important. This bad boy tells your engine control unit (ECU) the precise position of the camshaft. With this info, the ECU can time the fuel injection and ignition perfectly, ensuring your 5.9 Cummins runs smoothly and efficiently. Without it, your engine might struggle to start, run poorly, or not at all.
Symptoms of a Failing 5.9 Cummins CMP Sensor
So, how do you know if your CMP sensor is on the fritz? Here are some signs to look out for:
- Check Engine Light: This one's a no-brainer. If your truck's warning light comes on, it's time to investigate. - Hard Starting: Your 5.9 Cummins might struggle to turn over or refuse to start altogether. - Misfiring or Rough Idle: If your engine's running like it's got a case of the Monday blues, the CMP sensor could be the culprit. - Loss of Power: Feeling like your truck's lacking its usual oomph? A faulty CMP sensor could be the reason.
Locating the 5.9 Cummins Camshaft Position Sensor
Alright, let's roll up our sleeves and find that sensor! Grab your tools and follow along.
Under the Valve Cover
The 5.9 Cummins CMP sensor is typically located under the valve cover. Here's how to find it:
- 1. Pop the hood and locate the valve cover on the passenger side of the engine.
- 2. Remove the valve cover by unbolting it. You might need to use a breaker bar and a socket to get it loose. Be careful not to drop any bolts into the engine.
- 3. With the valve cover off, you should see the CMP sensor poking out from the side of the engine block. It's usually on the front, passenger side, near the camshaft.

Identifying the Sensor
The 5.9 Cummins CMP sensor is a Hall effect sensor, which means it uses a magnet and a coil to generate an electrical signal. It's typically a black, plastic housing with a single wire connected to it. The sensor itself looks like a small, rectangular block with a wire coming out one end.
Testing and Replacing the CMP Sensor
Now that you've found the sensor, it's time to test it. You can use a multimeter to check its resistance or a scan tool to see if it's throwing any codes. If it's faulty, don't worry – replacing it is a relatively straightforward process. Just make sure to get the right part; for a 5.9 Cummins, you'll want a Hall effect CMP sensor.
Here's a quick rundown of the replacement process:
- 1. Disconnect the electrical connector from the old sensor.
- 2. Remove the sensor by unthreading it from the engine block. You might need to use a sensor removal tool or a deep socket to get it out.
- 3. Install the new sensor by hand, making sure it's fully seated and the O-ring is in place.
- 4. Reconnect the electrical connector and double-check that everything's tightened down properly.
- 5. Clear the trouble codes from your truck's ECU using a scan tool, and you should be good to go!
Final Thoughts
