Finding Your 2015 Nissan Altima's Camshaft Position Sensor: A Step-by-Step Guide
Alright, guys, let's dive into this! If you're here, it's probably because your 2015 Nissan Altima is throwing some codes, and you're on the hunt for the camshaft position sensor (CMPS). No worries, we've got you covered! In this guide, we'll help you locate this crucial component in your 2015 Altima. So, grab your tools and let's get started!

Why the Camshaft Position Sensor Matters
Before we jump into the nitty-gritty, let's talk about why this sensor is so darn important. The camshaft position sensor monitors the position of the camshaft, which in turn tells your engine's computer (ECU) when to fire the spark plugs. In other words, it's the matchmaker that ensures your engine's combustion happens at just the right time. Without it, your Altima might not start, or it could run poorly and throw a check engine light.
Tools You'll Need
Before you start, make sure you've got these tools handy:
- Socket wrench with a 10mm socket - Ratchet - Pliers (needle-nose, if possible) - Flathead screwdriver - A new camshaft position sensor (if you're replacing it)
Locating the Camshaft Position Sensor in Your 2015 Nissan Altima
Step 1: Accessing the CMPS
First things first, you'll need to access the camshaft position sensor. Pop your hood and locate the intake manifold on the driver's side of the engine. It's the large, plastic component that covers the engine's intake ports. To remove it, you'll need to disconnect the following:
- The intake manifold's electrical connector (just unplug it) - The vacuum hose connected to the manifold (use your pliers to carefully squeeze and pull it off) - The three 10mm bolts holding the manifold in place (use your socket wrench and ratchet to remove them)
Once these are disconnected and removed, you should be able to wiggle the intake manifold free and set it aside.
Step 2: Finding the CMPS
With the intake manifold out of the way, you'll see the camshaft itself. It's the large, spinning metal component with lobes (cams) that open and close the engine's valves. The camshaft position sensor is located near the front of the camshaft, on the driver's side of the engine. It's a small, rectangular component with an electrical connector attached.
Step 3: Removing the CMPS
To remove the camshaft position sensor, follow these steps:
- 1. Unplug the electrical connector from the sensor. You might need to use a flathead screwdriver to gently pry it off.
- 2. Use your socket wrench and ratchet to remove the single bolt holding the sensor in place. It's a 10mm bolt, just like the ones you removed from the intake manifold.
- 3. With the bolt removed, you should be able to wiggle the camshaft position sensor out of its mounting location.
Testing and Replacing the CMPS
Now that you've located and removed the camshaft position sensor, you can test it (if you haven't already) and replace it if necessary. To test the sensor, you can use a multimeter to check its resistance or consult a professional diagnostic tool. If it's faulty, replace it with a new one, ensuring you install it in the correct orientation (the arrow on the new sensor should point towards the front of the engine).
Reinstalling the Intake Manifold
With the new camshaft position sensor installed, it's time to put everything back together. Reinstall the intake manifold by reversing the removal steps:
- 1. Align the intake manifold with the engine and gently push it into place.
- 2. Reconnect the vacuum hose and the electrical connector.
- 3. Tighten the three 10mm bolts using your socket wrench and ratchet, ensuring they're snug but not overtightened.
And there you have it, folks! You've successfully located, tested, and (if necessary) replaced the camshaft position sensor in your 2015 Nissan Altima. Don't forget to clear any stored codes using a diagnostic tool after you've finished.
Happy wrenching, and until next time, stay safe and keep your Altima running smooth!
