5 Top 5.9 Cummins Camshaft Position Sensor Picks for Your Ram
Hey there, Cummins owners! If you’re driving a trusty 5.9L Ram, you know how crucial every component is to keep that diesel beast roaring. One unsung hero in your engine’s sophisticated ballet of moving parts is the camshaft position sensor. It might be small, but when it goes bad, it can throw your entire engine’s timing out of whack, leading to a host of frustrating issues.
A failing 5.9 Cummins camshaft position sensor can cause anything from hard starting and rough idling to a sudden loss of power or even your engine stalling out. Don’t let a faulty sensor leave you stranded or scratching your head! We’ve put together a list of the top picks to help you find a reliable replacement that’ll get your Ram back to its peak performance. Let’s dive in and see which sensor will be the perfect fit for your rig.
What Does a Camshaft Position Sensor Do?
Before we jump into the reviews, let’s briefly touch on what this little gadget actually does. The camshaft position sensor (CPS) plays a vital role in your engine’s electronic control unit (ECU). It monitors the precise position and speed of your engine’s camshaft, sending this data to the ECU. This information is critical for the ECU to accurately time the fuel injection and ignition, ensuring your diesel engine runs smoothly, efficiently, and with optimal power. Think of it as the conductor of your engine’s timing symphony!

FAQ Section
Q1: What are the common symptoms of a bad 5.9 Cummins camshaft position sensor?
A1: Common symptoms include difficulty starting (especially when warm), prolonged cranking, rough idle, engine misfires, poor fuel economy, sudden loss of power, engine stalling, and illumination of the “Check Engine” light.
Q2: Can I replace the camshaft position sensor myself on my 5.9 Cummins?
A2: Yes, for many DIYers, replacing the 5.9 Cummins camshaft position sensor is a manageable task. It usually involves basic tools and is often located in an accessible spot on the engine. However, always refer to your specific vehicle’s service manual for detailed instructions.
Q3: What’s the difference between a camshaft and a crankshaft position sensor?
A3: Both sensors monitor rotational speed and position. The camshaft position sensor (CPS) tells the ECU the position of the camshaft, which controls valve timing. The crankshaft position sensor (CKP) tells the ECU the position and speed of the crankshaft, which is crucial for ignition and fuel injection timing. They often work together, and a fault in one can affect the other’s readings or the engine’s overall timing.
Q4: Will a faulty camshaft position sensor always trigger a “Check Engine” light?
A4: Not always immediately, but it’s very likely to eventually trigger a “Check Engine” light with a corresponding diagnostic trouble code (DTC), such as P0340 (Camshaft Position Sensor Circuit Malfunction). Symptoms like hard starting or stalling might appear before the light comes on.
Q5: How important is it to use an OEM-equivalent part for the 5.9 Cummins camshaft position sensor?
A5: While genuine OEM parts are generally the gold standard, many aftermarket sensors offer excellent quality and performance at a lower cost. Look for aftermarket sensors that meet or exceed OEM specifications, come from reputable brands, and have good user reviews. Certifications like ISO or CE can also indicate quality.
Q6: How long do camshaft position sensors typically last on a 5.9 Cummins?
A6: The lifespan of a camshaft position sensor can vary greatly depending on driving conditions, environmental factors, and manufacturing quality. They can last well over 100,000 miles, but some may fail much earlier. There’s no fixed replacement interval; they are usually replaced when symptoms of failure appear.
Q7: Can a bad camshaft position sensor cause my 5.9 Cummins to not start at all?
A7: Yes, absolutely. If the sensor provides inconsistent or no signal to the ECU, the engine might not be able to correctly time fuel injection and ignition, preventing it from starting or causing it to crank indefinitely without firing up.
