Choosing the Right Aftermarket Camshaft Sensor
While the original Mopar sensor is an option, many high-quality aftermarket brands are available that offer reliable performance, often at a better price. However, Chrysler vehicles can sometimes be sensitive to electronic sensors, so choosing a reputable brand is important. We've grouped the available brands into tiers based on quality and reputation.
Tier 1: OEM-Equivalent Quality
These brands are known for manufacturing parts that meet or exceed original equipment standards. Many professionals and experienced DIYers trust them for critical electronic components.
- Delphi: Often an original equipment manufacturer for many car brands. Delphi sensors are known for their reliability and robust design.
- NGK / NTK: NTK is the sensor division of NGK, a brand famous for spark plugs. They have a strong reputation for producing high-quality, dependable electronic parts.
- Hitachi: Another major OEM supplier, Hitachi parts are trusted for their engineering and durability.
- Standard Ignition (Blue Streak / Main Line): A long-standing aftermarket leader. Their main line (red box) and premium Blue Streak products are well-regarded. Avoid their budget "T-Series" line, which has a reputation for lower quality.
Tier 2: Quality Aftermarket & Value
These brands offer a solid balance of price and performance. They are a good choice for a daily driver repair where cost is a factor.
- Dorman: One of the largest aftermarket suppliers, Dorman specializes in direct-fit replacements. They offer a reliable solution that is widely available.
- Spectra: Known for fuel and engine management parts, Spectra offers sensors that are a dependable alternative to more expensive brands.
- Walker Products: Walker focuses on engine management and emission control parts, and their sensors are engineered to meet OE specifications.
- Holstein: This brand provides a range of sensors and is a solid choice for a cost-effective repair.
Tier 3: Economy Options
These brands are for the budget-conscious buyer. While they can get your vehicle back on the road, they may not have the same long-term durability as higher-tier options.
- Crown Automotive: Primarily known for Jeep parts, Crown offers budget-friendly replacement parts. Quality can be inconsistent based on owner reviews.
- Encore Automotive, Global Parts, Prenco, True Tech: These brands represent the most economical choices for this part.
A Note on Wiring
Sometimes, the P0340 or P0344 code is not caused by a bad sensor, but by a damaged wiring connector or harness. Before replacing the sensor, inspect the plug and wires for any cracks, corrosion, or loose connections. The plastic connector can become brittle from engine heat and break.

Frequently Asked Questions
Where is the camshaft position sensor on a PT Cruiser?
The camshaft position sensor on the 2.4L engine (both turbo and non-turbo) is located on the top of the cylinder head, on the driver's side of the engine, right next to the air filter box. It is held in by two 8mm bolts and is very easy to access.
Can I replace the PT Cruiser camshaft sensor myself?
Yes, this is a great DIY job for beginners. You only need basic hand tools (an 8mm socket or wrench and a screwdriver). The process involves removing the airbox cover, disconnecting the electrical plug, and unbolting the old sensor. The entire job usually takes less than 30 minutes.
🎬 See this step-by-step replacement walkthrough for the 2.4L engineIs there a recall for the PT Cruiser camshaft position sensor?
As of early 2026, there are no specific NHTSA recalls for the engine camshaft position sensor on the 2001-2010 Chrysler PT Cruiser. Failures are considered a standard maintenance or repair item.
What's the difference between a P0340 and P0344 code?
Both codes point to a problem with the camshaft position sensor. P0340 indicates a general circuit malfunction, meaning the computer is not getting a signal at all. P0344 indicates the signal is intermittent, meaning it's cutting in and out. This can be caused by a failing sensor or a loose/damaged wire. 🎬 Watch: How to fix P0340 and P0344 sensor faults Both codes often lead to the same repair: replacing the sensor and checking the connector.
Do I need to replace the crankshaft sensor at the same time?
No, it is not necessary. The camshaft and crankshaft sensors are separate parts that can be replaced independently. While they work together, you only need to replace the one that has failed. A diagnostic scan tool will specify which sensor circuit has a fault.
