Chrysler 300 Engine Camshaft Position Sensor: A 2012-2023 Replacement Guide
Fixing stalling, rough idling, and check engine lights on your Chrysler 300.
- First, confirm if your Chrysler 300 has the 3.6L V6 (4 sensors) or a HEMI V8 (1 sensor).
- Symptoms like stalling, rough idle, and a P0340/P0344 code strongly point to this sensor.
- For reliability, choose an OEM (Mopar) or premium aftermarket brand like NGK/NTK or Delphi.
- The replacement is extremely easy, requiring only a 10mm socket, making it a great DIY task.
Is Your Chrysler 300 Stalling or Running Rough?
If your 2012-2023 Chrysler 300 is suddenly stalling, struggling to start, idling poorly, or has the check engine light on, a failing camshaft position sensor is a very common culprit. This small electronic part plays a huge role, and when it fails, it can make your car unreliable. The good news is that on both the V6 and V8 engines, this is one of the easiest and most affordable repairs you can perform yourself.
Symptoms of a Bad Camshaft Position Sensor
A failing camshaft sensor will almost always let you know there's a problem. Look out for these common signs:
- Check Engine Light: This is the most common symptom. You'll likely see codes like P0340, P0344, P0345, or P0349.
- Engine Stalling: The engine may shut off unexpectedly while driving or when stopped, which can be dangerous.
- Difficulty Starting: The car may take longer than usual to crank before starting, or it may not start at all.
- Rough Idle and Misfires: The engine may shake or vibrate at idle because the timing is off.
- Poor Acceleration: You may notice hesitation or a lack of power when you press the gas pedal.
- Reduced Fuel Economy: Incorrect timing leads to inefficient fuel combustion, making you visit the gas station more often.
V6 vs. V8: A Critical Difference
Before buying a part, you must know which engine your Chrysler 300 has. The 3.6L Pentastar V6 has FOUR camshaft position sensors (two for intake, two for exhaust). The 5.7L or 6.4L HEMI V8 has only ONE sensor. Ordering the wrong number of parts is a common mistake.
Choosing the Right Aftermarket Sensor: Brand Matters
When it comes to electronic sensors on Chrysler vehicles, quality is extremely important. While budget parts are tempting, many owners report that cheap, no-name camshaft sensors fail quickly or are dead on arrival, leading to frustration and doing the job twice. For this specific part, it is highly recommended to invest in a quality brand.
Brand Quality Tiers:
- Tier 1: OEM & Premium Aftermarket (Recommended)
These brands are known for their reliability and are often the original equipment manufacturer. Spending a little more here can save you headaches later. Look for Mopar (OEM), NGK/NTK (often the actual OEM supplier), or Delphi. - Tier 2: Reputable Aftermarket
Brands like Standard Motor Products (Standard Ignition) and Hitachi generally offer good quality and are a solid choice if Tier 1 options aren't available. - Tier 3: Budget Brands
This category includes many store brands and lesser-known names like Dorman or Encore. While Dorman makes some solid replacement parts, their electronic sensors have mixed reviews. Use these brands with caution; while they may work, the risk of premature failure is higher.
A Note for 2011-2013 3.6L V6 Owners
If you have an early model 3.6L V6 and are getting recurring camshaft sensor codes (like P0344 or P0349) even after replacing the sensor, the issue might not be the part itself. There is a known issue where the Powertrain Control Module (PCM) requires a software update to fix a glitch that incorrectly triggers these codes. If you're on your second or third sensor, it may be time to consult a dealer about a PCM flash.

Frequently Asked Questions
How many camshaft sensors does my 2015 Chrysler 300 have?
It depends on your engine. If you have the 3.6L V6, you have four sensors. If you have the 5.7L or 6.4L HEMI V8, you have only one.
Can I replace the camshaft position sensor myself?
Yes, absolutely. This is a perfect job for a beginner. The sensor is easily accessible on top of the engine and is held in by a single 10mm bolt. The entire job should take less than 30 minutes.
What happens if I don't replace a bad sensor?
You risk the engine stalling at any time, which is a safety hazard. Continuing to drive can also lead to poor performance, bad fuel economy, and potentially damage to other components like the catalytic converter over the long term.
Why did my cheap aftermarket sensor fail after a week?
Low-quality electronic sensors often use inferior internal components that can't withstand the heat and vibration of the engine bay. This is why many experienced mechanics and owners strongly recommend using OEM (Mopar) or a premium aftermarket brand like NGK/NTK or Delphi for Chrysler vehicles.
