The 7 Best N52 Camshaft Position Sensors for Your BMW
If you own a BMW with the venerable N52 engine, you know it’s a fantastic powerplant – smooth, powerful, and reliable. However, like any precision machine, it has its quirks, and sometimes a tiny component can throw a wrench in the works. One such component is the N52 camshaft position sensor. This unsung hero plays a crucial role in your engine’s performance, helping the engine control unit (ECU) understand exactly where your camshafts are at any given moment. This data is vital for things like fuel injection timing and variable valve timing (VANOS), ensuring your engine runs smoothly and efficiently.
When an N52 camshaft position sensor starts to fail, you might notice a few tell-tale signs: a dreaded check engine light (CEL), rough idle, stalling, difficulty starting, or even reduced fuel economy. Don’t sweat it! Replacing this sensor is a common maintenance task, and thankfully, there are plenty of reliable options on the market. But with so many choices, how do you pick the right one?
We’ve done the legwork for you! In this guide, we’ll dive into the top 7 camshaft position sensors that are frequently chosen by N52 BMW owners.

Frequently Asked Questions about N52 Camshaft Position Sensors
Q1: What does a camshaft position sensor do in my N52 BMW?
A1: The camshaft position sensor (CPS) monitors the rotational speed and position of your engine’s camshafts. This information is sent to the engine control unit (ECU), which uses it to precisely time fuel injection and spark plug firing, as well as to control the VANOS (variable valve timing) system. Essentially, it helps your N52 engine run smoothly and efficiently.
Q2: What are the common symptoms of a bad N52 camshaft position sensor?
A2: Common symptoms include the illumination of the “Check Engine Light” (CEL), rough idle, engine stalling, difficulty starting, reduced engine power, poor fuel economy, and occasional engine misfires or vibrations. Diagnostic trouble codes (DTCs) like P0340 or P0341 are often triggered.
Q3: How many camshaft position sensors does an N52 engine have?
A3: The BMW N52 engine typically has two camshaft position sensors: one for the intake camshaft and one for the exhaust camshaft. Many aftermarket products are sold in pairs for this reason, allowing you to replace both simultaneously.
Q4: Can I replace the N52 camshaft position sensor myself?
A4: For mechanically inclined DIYers, replacing an N52 camshaft position sensor is a moderately easy task. The sensors are usually located on the front or side of the cylinder head and are held in place by a single bolt. It generally requires basic hand tools. However, if you’re uncomfortable with car repairs, professional installation is always recommended.
Q5: What’s the difference between an OEM and an aftermarket camshaft position sensor?
A5: OEM (Original Equipment Manufacturer) sensors are made by the same companies that supply parts to BMW for their original vehicle assembly (e.g., HELLA). Aftermarket sensors are made by other companies. OEM parts generally offer guaranteed compatibility and performance, often at a higher price. Aftermarket sensors can be more affordable, but quality and reliability can vary, so it’s important to choose reputable brands.
Q6: Will a faulty camshaft position sensor damage my N52 engine?
A6: While a bad camshaft position sensor typically won’t cause catastrophic engine damage directly, it can lead to various performance issues. If left unaddressed, persistent misfires or incorrect timing could put additional stress on other engine components over time. It’s always best to replace a failing sensor promptly to maintain optimal engine health.
Q7: How important is the N52 camshaft position sensor for engine performance?
A7: The N52 camshaft position sensor is crucial for engine performance. Without accurate camshaft position data, the engine’s ECU cannot optimize valve timing or fuel delivery, leading to inefficient combustion, reduced power output, decreased fuel efficiency, and a generally rough-running engine. It’s a key component in the modern engine’s precision operation.
