5 Top Camshaft Position Sensor CMP Reviews: Keep Your Engine Running Smoothly
Has your trusty vehicle been acting a bit off lately? Maybe the “Check Engine” light decided to make an unwelcome appearance, or you’ve noticed some rough idling, misfires, or even trouble starting? These could all be tell-tale signs that your camshaft position sensor CMP is on its way out. This tiny but mighty automotive sensor plays a critical role in your engine’s performance, helping the vehicle’s computer (ECU) know exactly where the camshaft is rotating. When it fails, your engine timing goes awry, leading to all sorts of headaches.
Don’t fret! Replacing a faulty camshaft position sensor doesn’t have to be a daunting task, and finding a quality replacement is key. We’ve scoured the market to bring you a list of top-notch options to get your ride back in prime condition. Let’s dive in!
What Does a Camshaft Position Sensor Do, Anyway?
Before we jump into the reviews, let’s quickly understand why this sensor is so important. The camshaft position sensor (often abbreviated as CMP sensor) works by monitoring the speed and position of your engine’s camshaft. This data is then sent to the Engine Control Unit (ECU), which uses it to precisely control critical engine functions like fuel injection timing and ignition timing. It works in conjunction with the crankshaft position sensor to provide a complete picture of your engine’s rotation. Without accurate data from your CMP sensor, your car’s computer can’t efficiently manage these processes, leading to the performance issues we mentioned.
How to Know When Your Camshaft Position Sensor is Failing?
Symptoms of a bad camshaft position sensor can vary, but here are some common indicators:
* Check Engine Light (CEL) Illumination: This is often the first sign, usually accompanied by specific diagnostic trouble codes (DTCs) like P0340.
* Engine Misfires or Rough Idling: Inaccurate timing can cause cylinders to fire incorrectly.
* Difficulty Starting: The ECU might struggle to determine the correct timing for starting the engine.
* Sudden Stalling: The engine might suddenly shut off, especially when coming to a stop.
* Decreased Fuel Economy: Inefficient timing can lead to more fuel consumption.
* Poor Acceleration or Hesitation: Your engine might not respond as expected when you press the gas pedal.
If you’re experiencing any of these, it’s a good idea to have your camshaft position sensor cmp checked out. Now, let’s look at some excellent replacement options.

Frequently Asked Questions (FAQ)
Q1: What are the common symptoms of a bad camshaft position sensor?
A1: The most common symptoms include your Check Engine Light illuminating, engine misfires, rough idling, difficulty starting, sudden engine stalling, and sometimes decreased fuel economy or poor acceleration. Your vehicle’s diagnostic system might also show specific codes like P0340.
Q2: Can I drive with a bad camshaft position sensor?
A2: While you might be able to drive a short distance, it’s not recommended. A faulty camshaft position sensor can lead to unreliable engine performance, unpredictable stalling, and potentially cause further damage to other engine components due to incorrect timing. It’s best to replace it as soon as possible.
Q3: Is a camshaft position sensor hard to replace?
A3: The difficulty level varies greatly depending on your vehicle’s make and model. Some camshaft position sensors are easily accessible, making it a relatively simple DIY job, while others are tucked away in harder-to-reach locations requiring more tools and expertise. Always consult your vehicle’s service manual or a professional mechanic.
Q4: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A4: Both are vital for engine timing. The camshaft position sensor (CMP) monitors the position of the camshaft, which controls valve opening and closing. The crankshaft position sensor (CKP) monitors the position and speed of the crankshaft, which drives the pistons. Together, they give the ECU the precise information needed to time fuel injection and spark delivery. While related, they perform distinct functions and are typically not interchangeable.
Q5: How much does it cost to replace a camshaft position sensor?
A5: The cost of the part itself can range from $20 to $100+, depending on your vehicle and whether you choose an OEM or aftermarket sensor. If you have it professionally replaced, labor costs can add another $50 to $200+, depending on the accessibility of the sensor and shop rates.
Q6: Can a bad camshaft position sensor cause my car to misfire?
A6: Yes, absolutely. If the camshaft position sensor provides inaccurate data or no data at all to the ECU, the engine’s timing (for both fuel injection and ignition) can be thrown off. This can lead to cylinders firing at the wrong time, resulting in noticeable engine misfires.
Q7: Does a camshaft position sensor affect fuel economy?
A7: Yes, indirectly. When the camshaft position sensor is faulty, the engine’s timing becomes less precise. This inefficiency can lead to the engine consuming more fuel than necessary to achieve the desired performance, resulting in decreased fuel economy.
