5 Top Nissan Altima Camshaft Position Sensor Reviews for a Smoother Ride
Is your Nissan Altima acting up? Maybe you’re experiencing a rough idle, difficulty starting, or that dreaded “Check Engine” light has popped on. These could all be signs pointing to an issue with your Nissan Altima camshaft position sensor. This tiny but mighty component plays a crucial role in your engine’s performance, ensuring everything runs smoothly and efficiently.
The camshaft position sensor works hand-in-hand with the crankshaft position sensor, providing vital information to your car’s engine control unit (ECU). This data helps the ECU determine the precise position of the camshafts, allowing it to correctly time fuel injection and ignition. When it malfunctions, your engine’s timing can go haywire, leading to misfires, reduced power, and even poor fuel economy.
Replacing a faulty Nissan Altima camshaft position sensor can often be a straightforward DIY task, saving you a trip to the mechanic.

Frequently Asked Questions about Nissan Altima Camshaft Position Sensors
Q1: What does a camshaft position sensor do in a Nissan Altima?
A1: The camshaft position sensor (CMP) monitors the rotational speed and position of the camshafts. It sends this data to the engine control unit (ECU), which uses it to determine when to inject fuel and ignite the spark plugs for optimal engine timing and performance.
Q2: What are the common symptoms of a bad Nissan Altima camshaft position sensor?
A2: Common symptoms include the “Check Engine” light illuminating (often with codes like P0340 or P0345), difficulty starting the engine, rough idling, engine misfires, stalling, reduced fuel economy, and a general lack of power or sluggish acceleration.
Q3: Can I drive my Nissan Altima with a bad camshaft position sensor?
A3: While your car might still run, it’s not advisable to drive long distances with a faulty sensor. It can lead to poor engine performance, increased fuel consumption, potential damage to other engine components (like the catalytic converter due to misfires), and could leave you stranded.
Q4: Is replacing a Nissan Altima camshaft position sensor a difficult DIY job?
A4: For many Nissan Altima models, replacing the camshaft position sensor is considered a relatively easy DIY task that can be done with basic hand tools. The sensors are usually accessible, often located near the top or side of the engine. However, always consult your vehicle’s service manual or a reliable repair guide for exact location and procedure.
Q5: How many camshaft position sensors does a Nissan Altima have?
A5: This depends on your Altima’s engine. 4-cylinder Altima models typically have one camshaft position sensor. V6 Altima models (e.g., 3.5L VQ35DE engine) often have two camshaft position sensors, one for each cylinder bank (Bank 1 and Bank 2). It’s crucial to identify your engine type and the specific sensor that needs replacing.
Q6: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A6: Both are crucial for engine timing. The camshaft position sensor (CMP) monitors the camshaft’s position, which dictates valve timing. The crankshaft position sensor (CKP) monitors the crankshaft’s position, which indicates piston position and engine speed. The ECU uses both signals to precisely time fuel injection and spark delivery.
Q7: Should I buy an OEM or aftermarket Nissan Altima camshaft position sensor?
A7: OEM (Original Equipment Manufacturer) sensors are designed specifically for your vehicle and are generally considered the most reliable, but they are also typically the most expensive. High-quality aftermarket sensors, like those reviewed above, can offer a cost-effective alternative with comparable performance and often come with good warranties. It’s best to choose a reputable aftermarket brand.
