Jeep Patriot Engine Camshaft Position Sensor Guide (2007-2017)
Having trouble with stalling or a rough idle? Your Patriot's camshaft position sensor could be the culprit.
- Your Patriot has two camshaft position sensors (intake and exhaust); it's wise to replace them in pairs.
- Symptoms include stalling, hard starts, rough idle, and a check engine light with codes like P0340 or P0344.
- This is a simple DIY replacement that requires basic tools and can be done in under an hour.
- For best results, use an OEM (Mopar) sensor or a premium aftermarket brand like Delphi or NGK, as Patriots can be sensitive to budget electronics.
Is Your Jeep Patriot Stalling or Running Rough?
A failing camshaft position sensor is a common issue for the 2007-2017 Jeep Patriot that can cause a range of frustrating problems. These sensors can fail from normal wear and tear, heat, or electrical issues. When one or both sensors start to go bad, the engine's computer gets confusing information, which can lead to noticeable performance problems. Ignoring these symptoms can lead to more significant engine issues or leave you stranded.
Symptoms of a Bad Camshaft Position Sensor
If your Patriot's camshaft position sensor is failing, you'll likely experience one or more of these signs:
🎬 Watch a detailed breakdown of these common sensor failure symptoms.- Check Engine Light: This is often the first and most common sign. The computer will store a trouble code, most commonly P0340, P0344, P0365, or P0369.
- Engine Stalling: The engine may shut off unexpectedly while you're driving or idling at a stoplight. This can be dangerous.
- Difficulty Starting: The engine may crank for a long time before it starts, or it might not start at all.
- Rough Idle and Sputtering: Your Patriot may shake, run unevenly, or feel like it's about to stall when you're stopped.
- Poor Acceleration: You might notice the vehicle feels sluggish, hesitates, or lacks power when you press the gas pedal.
- Reduced Fuel Economy: When the engine timing is off, it burns more fuel than necessary.
Known Issues: Recall and Wiring Problems
There was a safety recall (NHTSA 16V-907) for some 2016 Jeep Patriot models related to the wiring connectors for the camshaft and crankshaft position sensors. The terminals could be faulty, leading to an intermittent signal, stalling, or a no-start condition. While the recall only covered a specific production range of 2016 models, wiring issues can still occur on other years. Some owners have found that even after replacing the sensor, the problem persists, pointing to a wiring or connector issue.
Choosing the Right Aftermarket Sensor
When it comes to electronic sensors for the Jeep Patriot, not all aftermarket brands are created equal. Many experienced owners and mechanics report that these vehicles can be very picky about their sensors. Using a low-quality part can result in the same problems returning shortly after the repair, or even new error codes appearing.
Brand Quality Tiers
- Premium Aftermarket (OEM-Equivalent): Brands like Delphi, NGK (NTK), and Hitachi are often original equipment manufacturers for many car brands. They are engineered to meet or exceed OEM specifications and are generally the most reliable aftermarket choice. Delphi, for example, was the supplier for the recalled Mopar connectors.
- Trusted Aftermarket: Brands like Standard Motor Products (SMP) and Dorman offer a balance of quality and value. They are widely available and are a solid choice for this repair, though some forum discussions suggest OEM is still preferred for critical sensors.
- Value-Oriented: Brands such as Crown Automotive, Spectra, and others in the lower price range can be a hit-or-miss option. While they may work, there is a higher risk of premature failure or compatibility issues with the Patriot's sensitive electronics.
Pro Tip: Many Patriot owners strongly recommend using an original Mopar sensor or a premium aftermarket brand like Delphi or NGK/NTK to avoid issues. The small amount of money saved on a budget sensor may not be worth the potential for repeated repairs.
Expected Replacement Costs
The cost can vary depending on the brand you choose and local labor rates. Since the Patriot has two sensors, you may need to replace both.
| Part/Service | Estimated Cost |
|---|---|
| New OEM (Mopar) Sensor (Each) | $50 - $90 |
| New Aftermarket Sensor (Each) | $19 - $50 |
| Shop Labor | $60 - $120 |
Frequently Asked Questions
How many camshaft position sensors does a 2007-2017 Jeep Patriot have?
The 2.0L and 2.4L engines used in the Jeep Patriot have two camshaft position sensors. One is for the intake camshaft and the other is for the exhaust camshaft. They are located on the top of the engine head, one toward the front and one toward the back.
🎬 See exactly where the intake and exhaust sensors are located.Can I replace the camshaft position sensor myself?
Yes, this is a DIY-friendly job for someone with basic tools. The sensors are held in by a single 10mm bolt and are located in an accessible spot on top of the engine. The main steps involve removing the engine cover, disconnecting the air intake components for better access, unplugging the electrical connector, and removing the bolt. The entire job for one sensor can take less than an hour.
🎬 Follow this fast and easy DIY guide to replace both sensors.Should I replace both sensors at the same time?
While not strictly necessary, it is often recommended. Both sensors are the same age and have been exposed to the same conditions. If one has failed, the other may not be far behind. Replacing them in pairs can save you from having to do the same job again in the near future.
What happens if I don't replace a bad camshaft sensor?
Continuing to drive with a faulty sensor can lead to worsening symptoms like frequent stalling, which is a safety hazard. It can also cause poor fuel economy, failed emissions tests, and potentially damage other engine components like the catalytic converter over time due to an incorrect air/fuel mixture.
