7 Top 1999 Jeep Cherokee Camshaft Position Sensor Replacements
Your 1999 Jeep Cherokee is a legendary ride, known for its rugged durability and off-road prowess. But even the toughest vehicles need a little TLC, and sometimes, a small but vital component like the camshaft position sensor can throw a wrench in your plans. This tiny sensor plays a huge role in your engine’s performance, helping the Engine Control Unit (ECU) understand exactly where your camshaft is at any given moment. This information is crucial for precise ignition timing and fuel injection, ensuring your Jeep runs smoothly and efficiently.
When a 1999 Jeep Cherokee camshaft position sensor starts to go bad, you might notice a few tell-tale signs: a dreaded “check engine” light illuminating your dash, rough idling, misfires, poor acceleration, or even sudden engine stalling. Ignoring these symptoms can lead to bigger problems down the road. Replacing a faulty sensor is often a straightforward fix that can restore your Jeep’s pep and reliability.
Finding the perfect replacement can be a bit tricky, especially with variations in engine types (like the 2.5L versus the 4.0L) and model lines (Cherokee XJ vs. Grand Cherokee WJ) around the 1999 model year. That’s why we’ve scoured the market to bring you a selection of top-rated camshaft position sensors.

Frequently Asked Questions about the 1999 Jeep Cherokee Camshaft Position Sensor
Q1: What does the camshaft position sensor do in a 1999 Jeep Cherokee?
A1: The camshaft position sensor (CMP) monitors the rotational speed and position of the camshaft. This information is sent to the Engine Control Unit (ECU), which uses it to precisely control ignition timing and fuel injection, ensuring your engine runs smoothly and efficiently.
Q2: What are the common symptoms of a bad camshaft position sensor in a 1999 Jeep Cherokee?
A2: Common symptoms include the illumination of the “Check Engine” light, rough idling, misfires, reduced fuel economy, poor acceleration, hesitation, or even sudden engine stalling. In some cases, the vehicle might not start at all.
Q3: Is the camshaft position sensor the same for a 1999 Jeep Cherokee 4.0L and a 2.5L engine?
A3: No, typically the camshaft position sensor is different for the 4.0L and 2.5L engines in a 1999 Jeep Cherokee (XJ). The 4.0L engine often has its camshaft position sensing integrated into the distributor assembly (often called a synchronizer sensor), while the 2.5L uses a distinct sensor. Always verify the part number for your specific engine size.
Q4: Will a bad camshaft position sensor prevent my 1999 Jeep Cherokee from starting?
A4: Yes, a faulty camshaft position sensor can definitely prevent your Jeep from starting. Without accurate data from the sensor, the ECU can’t properly time spark and fuel delivery, which are essential for ignition.
Q5: How difficult is it to replace a camshaft position sensor on a 1999 Jeep Cherokee?
A5: For most DIYers, replacing a camshaft position sensor is a moderately easy task. It usually involves disconnecting the battery, locating the sensor, unplugging its electrical connector, unbolting it, installing the new one, and reconnecting everything. However, the exact procedure can vary slightly depending on your engine (2.5L or 4.0L) and specific model.
Q6: Do I need to clear the “Check Engine” light after replacing the sensor?
A6: Yes, after replacing the sensor, it’s a good practice to clear any stored diagnostic trouble codes (DTCs) using an OBD-II scanner. While the light might turn off on its own after a few drive cycles if the issue is resolved, clearing it manually confirms the fix and allows you to immediately monitor for any new codes.
Q7: Can a bad camshaft position sensor affect my fuel economy?
A7: Absolutely. When the camshaft position sensor isn’t providing accurate data, the ECU can’t optimize fuel injection and ignition timing. This can lead to inefficient combustion, causing your engine to use more fuel than necessary, resulting in decreased fuel economy.
