Dodge Dart Engine Oil Pressure Switch: A Comprehensive Guide for 2013-2016 Models
Is your Dodge Dart's oil light on? Here’s what you need to know about its engine oil pressure switch.
- A faulty oil pressure switch is a common issue on 2013-2016 Dodge Darts, often causing a false oil pressure warning light and the P0520 trouble code.
- Always check your oil level first when the oil light comes on. Never assume it's just the sensor.
- This is a manageable DIY replacement, but requires a special 1 1/16 inch deep socket and patience due to tight access on the back of the engine.
- Due to a TSB on the original part, choosing a quality aftermarket brand like Standard Ignition is a reliable and cost-effective option.
Is Your Dodge Dart's Oil Light On?
A glowing oil pressure light on the dashboard of your 2013-2016 Dodge Dart can be alarming. While it can signal a serious issue like low oil level or a failing oil pump, it often points to a simpler problem: a faulty engine oil pressure switch. This component is known to fail and can cause incorrect warnings. Understanding the symptoms and your replacement options can save you from unnecessary worry and costly repairs.
Common Symptoms of a Failing Oil Pressure Switch
When an oil pressure switch goes bad, it can give false signals. Here’s what to look for:
- Oil Light On, But Oil Level is Fine: This is the most common sign. The switch incorrectly tells the car's computer that oil pressure is low, triggering the warning light.
- Flickering Oil Light: The light may flicker or come on intermittently, especially at idle or during turns.
- Check Engine Light: A faulty sensor can trigger a Check Engine Light. You may find diagnostic trouble codes (DTCs) like P0520 or P0522 stored in the computer.
- Incorrect Gauge Readings: If your Dart has an oil pressure gauge, it might read zero, max out, or fluctuate wildly.
Stop and Check Immediately
Never ignore an oil pressure warning light. Always pull over safely and check your engine oil level first. Driving with low oil pressure can cause catastrophic engine damage. If the oil level is correct, the problem is likely the sensor, but it's critical to be sure.
Known Issues for 2013-2016 Dodge Dart
Chrysler issued a Technical Service Bulletin (TSB), number 18-034-14, for 2013-2014 Dodge Darts with the 2.0L and 2.4L engines. This TSB addresses the MIL (Check Engine Light) being illuminated with DTC P0520 - Engine Oil Pressure Sensor Circuit. 🎬 Watch: Step-by-step guide to fixing P0520 and P0522 codes. The bulletin advises technicians to replace the original oil pressure sensor with a revised part to fix the issue, indicating that the original sensors were a known problem.
Choosing the Right Aftermarket Part
For the Dodge Dart, the OEM Mopar switch is a reliable choice, but quality aftermarket options can offer significant savings. The key is to choose a reputable brand.
- Standard Ignition (Standard Motor Products): Often considered a top-tier aftermarket brand, Standard produces parts that meet or exceed OE specifications. They are known for robust testing and quality materials, making them a reliable choice for a critical sensor like this.
- Rostra Powertrain: Rostra is a well-established manufacturer of electronic automotive components, including sensors and switches. They are ISO-certified and known for producing quality parts, though they are more specialized in transmission components.
- Global Parts (and other budget brands): These are typically the most affordable option. While they can work, their long-term durability and the accuracy of their readings can be inconsistent. Some owners report issues with budget sensors failing prematurely or causing incorrect readings right out of the box.
Pro Tip: OEM vs. Aftermarket
Given the TSB for the original part, choosing a quality aftermarket replacement like Standard Ignition, which is designed to meet or exceed original specs, is a sound decision. Some owners who have used cheaper, no-name aftermarket sensors have reported the oil light returning, forcing them to do the job twice. Spending a little more on a trusted brand can save you time and hassle.

Frequently Asked Questions (FAQ)
Where is the oil pressure switch on a 2013-2016 Dodge Dart?
On the 2.0L and 2.4L engines, the oil pressure switch is located on the back of the engine block, on the passenger side, underneath the water pump area. 🎬 See exactly where the sensor is located on the engine. It can be difficult to see and access without removing the plastic engine cover and air intake ducting.
Can I replace the Dodge Dart oil pressure switch myself?
Yes, this is a DIY-feasible job for someone with basic mechanical skills and tools. The main challenge is the tight access. You will need to remove the engine cover and possibly some air intake components. A special deep socket (typically 1 1/16 inch) designed for oil pressure sensors is highly recommended.
🎬 Watch this walkthrough to see the replacement process in action.What happens if I ignore a bad oil pressure switch?
Ignoring it is risky. If the switch is faulty and constantly has the light on, you might ignore a real low-pressure event, which could destroy your engine. Conversely, if the switch has failed and can no longer detect a problem, it won't warn you when your engine is actually being starved of oil. For the low cost of the part, it's not worth the risk.
Is an aftermarket switch as good as the OEM Mopar part?
A high-quality aftermarket switch from a brand like Standard Ignition is generally considered to be as reliable as the OEM part, and sometimes better, especially when an OEM part has a known issue covered by a TSB. Cheaper, unbranded parts can be a gamble and may not last as long or provide accurate readings.
