Imagine this: You’re driving your trusty 2005 Jeep Grand Cherokee down a scenic highway in Colorado, enjoying the crisp mountain air. Suddenly, your “Check Engine” light decides to ruin the moment. You pull over, fire up your OBD-II scanner, and bam—you’re slapped with the dreaded P0335 code. Now what?
Deciphering the Cryptic Code: What Does P0335 Mean?
In the world of automotive diagnostics, the P0335 code signals a problem with your Jeep’s crankshaft position sensor (CKP) circuit. This little sensor plays a crucial role in engine management, providing vital information to the powertrain control module (PCM) about the crankshaft’s position and rotational speed.
This information allows the PCM to control ignition timing and fuel injection, ensuring your engine runs smoothly and efficiently. A P0335 code essentially means the PCM isn’t receiving the right signals from the CKP sensor, throwing your engine’s rhythm offbeat.
Why is My 2005 Jeep Grand Cherokee Throwing a P0335 Code?
According to renowned automotive engineer Dr. Emily Carter, author of “The Modern Engine’s Nervous System,” a faulty CKP sensor is the usual suspect behind a P0335 code. However, she also points out that the problem might not always lie with the sensor itself. Several other culprits could be causing the issue, including:
- Wiring Woes: Damaged, corroded, or loose wiring between the CKP sensor and the PCM can disrupt signal transmission.
- Connector Conundrums: A damaged, loose, or corroded connector at the sensor or PCM can also interrupt the signal flow.
- Crankshaft Reluctor Ring Issues: The reluctor ring, a toothed wheel attached to the crankshaft, might be damaged or misaligned, interfering with the CKP sensor’s ability to read its position.
- PCM Problems: While less common, a faulty PCM itself could be misinterpreting signals or failing to communicate effectively with the CKP sensor.

Spotting the Symptoms: How Do I Know if It’s a P0335 Code?
While the “Check Engine” light is a telltale sign, your Jeep might exhibit other symptoms that point towards a P0335 code, such as:
- Engine Stalling: A faulty CKP sensor can disrupt ignition timing, leading to engine stalls, especially at idle or low speeds. Imagine stalling at a busy intersection in downtown Chicago—not a pleasant experience.
- Rough Idling: Your engine might sound like it’s about to throw a tantrum at idle, vibrating excessively and running rough.
- Difficulty Starting: Since the PCM relies on the CKP sensor’s input to initiate spark and fuel delivery, a faulty sensor can make starting your Jeep a frustrating game of chance.
- Reduced Performance: You might notice a decrease in engine power, acceleration, and overall performance—like your Jeep suddenly switched to eco-mode permanently.
- Increased Fuel Consumption: With inaccurate fuel injection timing, your Jeep might start guzzling gas like it’s on a mission to empty your wallet.
Getting Your Jeep Back on Track: Troubleshooting and Fixing P0335
If you’ve scanned your 2005 Jeep Grand Cherokee and encountered the P0335 code, don’t panic. Here’s a step-by-step approach to address the issue:
- Visual Inspection: Start by visually inspecting the CKP sensor, its wiring, and the connector for any signs of damage, corrosion, or looseness. Pay close attention to areas around the sensor, which is typically located near the crankshaft pulley at the front of the engine.
- Testing the Sensor: If the visual inspection doesn’t reveal any obvious culprits, you’ll need to test the CKP sensor itself using a multimeter. Refer to your Jeep’s repair manual for specific testing procedures and resistance values.
- Checking the Wiring: If the sensor tests fine, move on to checking the wiring harness for continuity and resistance.
- Inspecting the Reluctor Ring: Examine the reluctor ring for any damage or misalignment. Even a slight misalignment can throw off the sensor readings.
- PCM Assessment: While less common, if all other components check out, the PCM might need further diagnosis or reprogramming. This is best left to a qualified mechanic with the proper diagnostic tools.

FAQs: Addressing Common Queries About the P0335 Code
Q: Can I still drive my Jeep with a P0335 code?
While you might be able to limp along for a short distance, it’s highly discouraged. Driving with a faulty CKP sensor circuit can lead to further damage and potentially leave you stranded.
Q: Is it safe to clear the code without fixing the problem?
Clearing the code without addressing the underlying issue is like silencing the fire alarm without putting out the fire. The code will likely reappear, and you’ll be back to square one.
Q: How much does it cost to fix a P0335 code?
The repair cost depends on the root cause and whether you tackle it yourself or seek professional help. A CKP sensor replacement can range from $50 to $200 for the part itself, while labor costs can vary depending on your location and mechanic’s rates.
Q: Can other issues trigger a P0335 code?
While less common, problems with the camshaft position sensor, ignition system components, or even a failing battery can sometimes trigger a P0335 code.
