Is Your Dodge Dart Running Rough or Losing Power? It Could Be the Knock Sensor.
A failing knock sensor can cause a range of frustrating problems for your 2013-2016 Dodge Dart. Because this sensor is critical for engine protection and performance, the car's computer will take protective measures when the sensor fails, often reducing power to prevent damage. This can make your car feel sluggish and inefficient. 🎬 Watch: How a faulty sensor causes power loss and hesitation. Understanding the symptoms and choosing a quality replacement part is key to getting your Dart running properly again.
Known Issues & Recalls
While there are no specific recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the ignition knock sensor on the 2013-2016 Dodge Dart, it's important to be aware of other vehicle recalls. Several recalls exist for issues like shifter cable bushings and software updates, which can affect overall vehicle performance and safety. A knock sensor code doesn't always mean the sensor itself is bad; it can be triggered by other engine problems.
Choosing the Right Aftermarket Knock Sensor
When replacing the knock sensor, you have a choice between OEM (Original Equipment Manufacturer) Mopar parts and a wide range of aftermarket brands. For a critical sensor like this, quality matters.
- Premium Aftermarket (Bosch, Delphi, NGK): These brands are often original equipment suppliers to many automakers. They have a strong reputation for quality and reliability that is very close to, or sometimes the same as, the OEM part. Choosing one of these brands is a safe bet for ensuring compatibility and long-term performance without paying the full dealership price for a Mopar-branded part.
- Standard Aftermarket (Standard Ignition, Walker Products, Holstein): These brands offer a good balance of quality and value. They are generally reliable and meet or exceed OEM specifications, making them a solid choice for most repairs.
- Economy Brands (Global Parts, various unbranded online parts): While the low price is tempting, budget-friendly sensors can be a gamble. Some owners report these parts failing quickly or not working correctly out of the box, leading to the need to do the job twice. For a part that can be difficult to access, it's often worth spending a little more for a reputable brand.
Pro Tip: Check the Connector
Before ordering, it's a good idea to visually inspect your old sensor and its electrical connector if possible. Wires can become brittle and break, and connectors can get corroded. Sometimes, the problem is the connector, not the sensor itself.

Frequently Asked Questions
Where is the knock sensor located on a Dodge Dart?
The knock sensor is bolted directly to the engine block. On the Dodge Dart engines (1.4L, 2.0L, and 2.4L), it is typically found on the back side of the engine block, near the starter. Access can be difficult, and some mechanics may remove the intake manifold for easier access, though it might be possible to reach it from underneath the car by removing the starter.
Can I replace the knock sensor myself?
This is a moderately difficult job for a DIY mechanic. The sensor's location on the back of the engine makes it hard to reach. It requires working in tight spaces, and you may need to remove other components like the starter to get to it. If you are not comfortable working in tight spaces or removing other engine components, it may be best to leave this job to a professional.

P0325 is the most common trouble code for a knock sensor issue. It means the car's computer has detected a malfunction in the knock sensor circuit. This could be a problem with the sensor itself, the wiring, or the connector. The computer sees a voltage from the sensor that is either too high or too low, indicating a fault.

For electronic sensors, using a high-quality part is important. While an OEM Mopar part is always a safe choice, top-tier aftermarket brands like Bosch, Delphi, or NGK are excellent alternatives that provide similar quality and reliability for less money. Cheaper, lesser-known brands can be unreliable and are often not recommended, especially for a part that is difficult to replace.
