Chrysler Aspen (2007-2009) Engine Oil Pressure Switch and Sensor Guide
Having oil pressure warnings on your 2007-2009 Chrysler Aspen? This guide is for you.
- A bad oil pressure switch is a common failure, but always check your oil level first.
- Symptoms include a flickering oil light, a faulty gauge, and specific Check Engine Light codes (P0520).
- Using a genuine Mopar replacement part is strongly recommended to avoid electrical and computer-related issues.
- Do not drive the vehicle if the oil pressure light is on, as you can't be sure if it's a bad sensor or true low oil pressure.
Is Your Chrysler Aspen's Oil Light On?
A glowing or flickering oil pressure light on your 2007-2009 Chrysler Aspen is a serious warning. While it could mean you have a major engine problem, it is often caused by a failing engine oil pressure switch. This part is known to fail and can cause confusing symptoms. Before you panic, it's important to understand what to look for and how to choose the right replacement part. A forum member with a 2007 Aspen reported that using a non-Mopar sensor caused major electrical problems and forced the vehicle into limp mode; switching to a genuine Mopar part fixed the issues completely. This highlights the sensitivity of the Aspen's electrical system.
First, Check Your Oil Level
Before assuming the sensor is bad, always check your engine oil level and condition. A warning light can mean your oil is dangerously low. If the oil level is correct, the problem is likely the sensor or a more serious internal engine issue. Do not continue to drive if the oil light is on and the engine is making knocking or ticking noises.
Symptoms of a Failing Oil Pressure Switch
When the oil pressure switch fails on your Aspen, you may notice one or more of these signs:
- Oil Pressure Warning Light: The light on your dashboard may stay on constantly, or it might flicker on and off, especially during turns or acceleration.
- Incorrect Gauge Reading: If your Aspen has an oil pressure gauge, it might read zero, be stuck at maximum, or jump around wildly.
- Check Engine Light: The vehicle's main computer can detect a problem with the sensor's signal and will turn on the check engine light. You may see codes like P0520, P0521, or P0522 🎬 Watch this diagnostic walkthrough for the P0520 code on an Aspen. when you scan the vehicle.
- Oil Leaks: The sensor itself can leak oil. You might see residue on the sensor or drips on the ground below the engine.
Choosing the Right Aftermarket Part for Your Aspen
For many parts, aftermarket options are a great value. However, for this specific sensor on this specific vehicle, the choice is critical. Based on owner experiences, using a part that doesn't communicate perfectly with the Aspen's computer can create more problems than it solves.
Brand Quality Tiers
- Tier 1: OEM (Mopar): This is the safest and most recommended choice. Chrysler has released updated versions of this sensor over the years to improve reliability. While it is the most expensive option, it is the most likely to work correctly without causing electrical issues.
- Tier 2: Premium Aftermarket (Standard Ignition, Walker Products): Brands like Standard and Walker are well-known and produce parts that aim to meet or exceed original specifications. They are a viable option if OEM is not available, but some Mopar owners have reported shorter lifespans with aftermarket sensors.
- Tier 3: Value Brands (Crown, Holstein, True Tech, etc.): These are the most affordable options. Given the documented sensitivity of the Aspen's electronics, these parts carry a higher risk of incompatibility or premature failure. They should only be considered if budget is the absolute primary concern.
Pro Tip: Use the Latest Part Number
Mopar has updated the part number for this sensor multiple times. For example, part number 5149062AA was replaced by 5149062AB. Using the latest revised part from the dealer or a trusted OEM supplier ensures you get the most reliable version.

Frequently Asked Questions
Can I drive my Aspen with a bad oil pressure switch?
No. If the warning light is on, you cannot be sure if you have a cheap, faulty sensor or a serious lack of oil pressure that could destroy your engine. It is not safe to drive. Have the vehicle towed to a repair shop or fix it before driving.
Where is the oil pressure switch located on the Chrysler Aspen?
The location is slightly different for the 4.7L and 5.7L engines, but it is generally found screwed into the engine block, often near the oil filter housing or behind the alternator. You will need a special deep socket designed for oil pressure switches 🎬 Watch this DIY guide to fixing oil pressure engine codes. to remove and install it without damage.
I replaced the sensor, but the oil light still flickers. What's wrong?
If you used a quality Mopar sensor and the light still comes on, you may have a more serious issue. The two most common causes are a failing oil pump or, more frequently on high-mileage engines, a clogged oil pump pickup screen 🎬 See how to tell if flickering is a sensor or engine wear. in the oil pan. This requires removing the oil pan to inspect and clean, which is a much larger job.
Why is using a Mopar sensor so important for this truck?
The engine computer in your Aspen relies on precise data from its sensors. As shown in forum discussions, the voltage signals from some aftermarket sensors can be slightly different from the original, which the computer interprets as a major fault, leading to limp mode or other strange electrical behavior. Using the Mopar part eliminates this variable.
