Ram 1500 Engine Oil Pressure Switch Guide (2011-2022)
Is your Ram 1500's oil pressure gauge acting crazy? Here’s what you need to know before you buy a new sensor.
- An oil pressure gauge reading maxed out at 99 PSI is a classic sign of a failed sensor, not a dangerous pressure spike.
- Ram owners overwhelmingly recommend using a genuine Mopar replacement sensor to avoid accuracy issues and premature failure common with aftermarket parts.
- The replacement is a simple DIY job, but you must have a special 27mm or 1 1/16" deep oil pressure switch socket.
- A Technical Service Bulletin (TSB) exists for 2013-2014 models, indicating a known issue that required a revised part from the manufacturer.
Is Your Ram 1500 Oil Pressure Gauge Lying to You?
One of the most common electronic failures on the 2011-2022 Ram 1500 is the engine oil pressure sensor. Many owners first notice a problem when they see the oil pressure gauge on the dashboard behaving strangely. It might be pegged at the maximum reading, like 96 or 99 PSI, even when the engine is off. Or, it might drop to zero and then jump back up for no reason. While this is alarming, it doesn't always mean your engine is in trouble. More often than not, it's simply a bad sensor.
Don't Ignore Warning Lights
If your red oil pressure warning light is on and you hear any new engine noises like ticking, knocking, or clattering, pull over and shut off the engine immediately. This could signal a true loss of oil pressure, which can destroy an engine in minutes. If there are no noises and the gauge is just acting erratically, it is likely a sensor failure, but you 🎬 Watch: Diagnostic steps to confirm a failed oil pressure sensor. should still get it checked as soon as possible.
Common Failure Symptoms
- Check Engine Light: Often, a failed sensor will trigger the check engine light.
- Erratic Gauge Readings: The gauge may read max pressure (e.g., 96 PSI) or zero, or fluctuate wildly.
- Oil Pressure Warning Light: The light may turn on, or flicker, especially at idle.
- Leaking Oil: The sensor itself can develop a leak, dripping oil from its body or electrical connector.
Choosing the Right Aftermarket Part: A Word of Caution
When it comes to electronic sensors on the Ram 1500, not all parts are created equal. Forum discussions among Ram owners show a strong preference for using the original equipment (OEM) Mopar sensor.
Tier 1: OEM (Mopar)
This is the most recommended option. Owners report that Mopar sensors are the most reliable and least likely to cause problems. While they cost more than some aftermarket brands, the peace of mind is often worth it to avoid incorrect readings or premature failure. There was even a Technical Service Bulletin (TSB 08-053-14) for 2013-2014 models that involved replacing the original sensor with a revised Mopar part.
Tier 2: Premium Aftermarket (Standard Ignition, Holstein)
Brands like Standard Motor Products (SMP) and Holstein are well-known in the aftermarket world. Some owners have used them with success. However, the risk of getting a part that reads incorrectly or fails early is higher than with OEM. If you choose this route, be prepared for the possibility that it might not solve the problem.
Tier 3: Value Brands (Crown, Walker, etc.)
While the low price is tempting, owners frequently report issues with value-priced sensors. Problems include inaccurate readings right out of the box, causing new error codes, or failing within a few months. For a part this critical, saving a few dollars here could lead to major headaches down the road.
Pro Tip: Check Your Oil Filter
Some Ram owners have noticed that certain cheap aftermarket oil filters with poor anti-drainback valves can cause temporary weird oil pressure readings, especially on a cold start. Before replacing the sensor, make sure you are using a quality oil filter.
Cost to Replace Ram 1500 Oil Pressure Switch
| Part Type | Part Cost | Labor Cost (Shop) | Total Estimated Cost |
|---|---|---|---|
| New OEM (Mopar) | $50 - $95 | $75 - $140 | $125 - $235 |
| New Aftermarket | $13 - $90 | $75 - $140 | $88 - $230 |
Cost estimates are approximate and can vary by location and vehicle engine type.
Frequently Asked Questions (FAQ)
Can I replace the oil pressure sensor myself?
Yes, this is a common DIY repair for Ram 1500 owners. The sensor is usually located on the passenger side of the engine, just above the oil filter. The 🎬 See this walkthrough for locating and replacing the sensor. main challenge is the tight space. You will need a special deep socket (either 27mm or 1 1/16 inch) to fit over the sensor's plastic connector housing. Many people perform this job during an oil change since you're already working in that area.
Is my engine about to fail if the gauge reads zero?
Not necessarily. If the gauge suddenly drops to zero but the engine sounds normal (no knocking or ticking), it's very likely a failed sensor or a wiring issue. The sensor failing in an 'open circuit' state will cause a zero reading. However, you should not continue driving, as you have no way of knowing your actual oil pressure.
Why do so many people insist on using a Mopar sensor?
Ram trucks can be sensitive to aftermarket electronic parts. Owners have repeatedly found that aftermarket oil pressure sensors may be poorly calibrated, leading to incorrect gauge readings, new check engine light codes (like P0520 after fixing a P0523), or they 🎬 Watch: How to fix P0520 and P0522 error codes. fail very quickly. Using a genuine Mopar part is the most reliable way to ensure the repair is done right the first time.
Are there any recalls for the oil pressure switch on the Ram 1500?
No, there are no specific safety recalls for the engine oil pressure switch on 2011-2022 Ram 1500s. However, Chrysler did issue a Technical Service Bulletin (TSB 08-053-14) for some 2013-2014 models, instructing dealers to replace the original sensor with an updated part if certain trouble codes were present.
