7 Best Camshaft Position Sensors for Your Jeep 4.0
Is your beloved Jeep 4.0 giving you a headache? Maybe it’s acting sluggish, idling rough, or that dreaded “Check Engine Light” has decided to make a permanent home on your dashboard. If so, there’s a good chance your camshaft position sensor Jeep 4.0 might be the culprit.
This seemingly small part plays a huge role in your engine’s performance. It tells your Jeep’s computer (the ECU) exactly where the camshaft is, which is crucial for things like ignition timing and fuel injection. When it goes bad, your Jeep can run poorly, struggle to start, or even stall out.
Don’t fret! Replacing your camshaft position sensor is a common fix, and luckily, there are plenty of quality options out there. To help you get your Jeep back on track, we’ve rounded up and reviewed 7 top camshaft position sensor Jeep 4.0 options, highlighting what makes each one stand out. Let’s dive in!
Why Your Jeep 4.0 Needs a Reliable Camshaft Position Sensor
Before we get to the reviews, let’s quickly touch on why this sensor is so vital. Your Jeep 4.0 engine, whether it’s in a Wrangler, Cherokee, or Grand Cherokee, relies heavily on precise timing. The camshaft position sensor monitors the rotational speed and position of the camshaft. This data is then sent to the engine control unit (ECU), which uses it to perfectly time fuel delivery and spark.
When the sensor starts to fail, this precise timing gets thrown off, leading to symptoms like:
* Intermittent stalling
* Rough idling or hesitation
* Difficulty starting, especially when warm
* Decreased fuel efficiency
* Illuminated Check Engine Light (often with codes like P0340 or P0341)
Replacing a faulty sensor isn’t just about fixing a light; it’s about restoring your Jeep’s optimal performance and preventing further engine issues.

FAQ Section
Q1: What does a camshaft position sensor do in a Jeep 4.0 engine?
A1: The camshaft position sensor (CPS) monitors the rotational speed and position of the camshaft. This information is crucial for the Engine Control Unit (ECU) to precisely control ignition timing and fuel injection, ensuring your Jeep 4.0 runs smoothly and efficiently.
Q2: What are the common symptoms of a bad camshaft position sensor in a Jeep 4.0?
A2: Common symptoms include your Check Engine Light (CEL) illuminating (often with codes like P0340 or P0341), rough idling, engine stalling (especially after warming up), difficulty starting, poor acceleration, and reduced fuel economy.
Q3: Is it difficult to replace the camshaft position sensor on a Jeep 4.0?
A3: For most Jeep 4.0 models, replacing the camshaft position sensor is considered a relatively straightforward DIY task. It typically involves locating the sensor, disconnecting its wiring harness, unbolting it, and then installing the new sensor in reverse order. Most replacement sensors are designed as direct, plug-and-play components.
Q4: Do I need to clear the Check Engine Light after replacing the camshaft position sensor?
A4: Yes, after replacing the sensor, it’s highly recommended to clear the diagnostic trouble codes (DTCs) from your Jeep’s computer using an OBD-II scanner. While sometimes the light may turn off on its own after several drive cycles if the issue is resolved, clearing the codes ensures a fresh start and confirms the fix.
Q5: Are all camshaft position sensors for Jeep 4.0 engines compatible across all years and models?
A5: Not necessarily. While many 4.0L engines share similar components, there can be subtle differences in the sensor’s design or connector type depending on the specific year (e.g., Jeep Wrangler, Cherokee, Grand Cherokee) and even the engine’s build date. Always double-check the product’s compatibility list, OEM part numbers, and use your vehicle’s make, model, and year when purchasing to ensure a perfect fit.
Q6: What’s the difference between a camshaft position sensor and a crankshaft position sensor?
A6: Both are vital for engine timing. The camshaft position sensor (CPS) tells the ECU the position of the camshaft, which dictates valve timing. The crankshaft position sensor (CKP) monitors the position and speed of the crankshaft, which determines piston position. The ECU uses data from both to accurately time spark and fuel delivery.
Q7: How much does a new camshaft position sensor for a Jeep 4.0 typically cost?
A7: The cost can vary depending on the brand, quality, and whether it’s just the sensor or a complete assembly. Generally, you can expect to pay anywhere from $20 to $100 for a quality aftermarket camshaft position sensor for your Jeep 4.0. Complete synchronizer assemblies will naturally be at the higher end of that range or more.
