If you are looking for an ENA Oil Pressure Sensor Switch review, the main question is fitment, not novelty.
This part is aimed at owners who need a replacement for a long list of GM applications and want a straightforward OEM-style swap.
Oil Pressure Sensor Switch Review Summary
The ENA Oil Pressure Sensor Switch makes sense for buyers who already know they need a compatible replacement and want a single-part solution rather than a universal guess.
Its value is in the broad fitment list, the included one-piece package, and the fact that the listing calls out common replacement numbers, which helps when you are comparing an old sensor against a catalog photo or part cross-reference.
This is not the kind of product where you buy on appearance alone.
The strongest reason to choose it is if your vehicle and engine family line up with the listed applications and you want a replacement part that is built around those fitment references.
If you need a sensor for one of the supported Chevy, Buick, Pontiac, Saturn, GMC, Cadillac, or related applications, it is the kind of practical listing that can save time.
If your vehicle is outside that ecosystem, or if you are unsure about engine and year overlap, it is better to verify fitment first and keep alternatives in view.

Key Features and Specifications of Oil Pressure Sensor Switch
The listing identifies this as an ENA oil pressure sensor switch for PS402, D1849A, 12635992, 12610185, and related replacements.
That matters because buyers of this type of part often search by the number on the old sensor, the engine bay label, or a parts catalog cross-reference rather than by brand name alone.
The advertised compatibility spans a wide range of GM vehicles, including Chevy Cavalier, Classic, Cobalt, Equinox, HHR, Impala, Malibu, Orlando, and Zafira; Buick LaCrosse, Regal, and Verano; Pontiac G5, G6, Grand Am, Pursuit, Solstice, and Sunfire; Saturn Aura, Ion, L100, L200, L300, LS, LS1, LW1, LW200, Sky, and Vue; and GMC Terrain.
The description also calls out multiple engine sizes, including 2.0L, 2.2L, 2.4L, 3.0L, and 3.6L in some supported applications.
Here are the important listing facts in plain language:
- Brand: ENA
- Part type: oil pressure sensor switch
- Replacement references: PS402, D1849A, 12635992, 12610185, 24577642, OPS183, 1S6798, V50720029, 1815427
- Package content: one sensor
- Warranty: 1 year limited warranty
The most useful thing about this specification set is that it gives you enough data to compare against an old sensor or a vehicle parts lookup without overstating anything.
It does not present itself as a performance upgrade.
It is a replacement part with a wide list of intended applications.
Pros and Cons of Oil Pressure Sensor Switch
Pros
- Broad GM compatibility list covers many common repairs
- Multiple cross-reference numbers make part matching easier
- Single-piece package keeps the purchase straightforward

Cons

Who Should Buy Oil Pressure Sensor Switch?
This is a good match for owners or repair shoppers who need an oil pressure sensor switch for a supported Chevy, Buick, Pontiac, Saturn, GMC, Cadillac-related application and prefer to buy against fitment data instead of browsing generic sensors.
It also suits buyers who already have a failed or suspect part and can compare the replacement number directly.
It is especially relevant if you are trying to keep a repair moving with a part that matches the listing’s cross-reference numbers.
In that case, the product’s value is not about extra features; it is about being a plausible, direct replacement for a known application.
You should skip it if you are still unsure about the exact engine, model year, or fitment family.
A sensor like this is only useful when the vehicle match is solid.
If your car is not on the supported list, or if your parts catalog gives you a different reference, spend the extra time verifying before ordering.
Fitment and Replacement Factors for Oil Pressure Sensor Switch
Cross-Reference Matching
The presence of several replacement numbers is the biggest practical clue in the listing.
Buyers who are replacing an original sensor can compare the old part number or catalog entry against the references shown here to avoid ordering the wrong variant.
Vehicle and Engine Coverage
The fitment list is broad, but it is also specific enough to require attention.
The same part may fit several years of a model line while skipping others, and the listed engine families matter just as much as the badge on the trunk.
Repair Context
This is best treated as a maintenance replacement, not a tuning part.
If the old sensor is failing or the vehicle is showing a symptom tied to oil pressure sensing, the smartest approach is to confirm compatibility and swap in a part built for that exact use case.
Warranty and Ownership
The 1 year limited warranty is modest, but it is still useful in a category where buyers mainly want confidence that the part is the right match and covered for early defects.
For a basic replacement sensor, that kind of support is enough to matter.
Alternatives to Oil Pressure Sensor Switch
If you want to compare before buying, these Amazon search pages are the most relevant alternatives:
- ACDelco oil pressure sensor switch search
- Motorcraft oil pressure sensor switch search
- Standard Motor Products oil pressure sensor search
- GM genuine oil pressure sensor switch search
ACDelco and GM genuine parts are the most natural comparisons if you want to stay close to original-equipment sourcing.
Motorcraft is less directly relevant for most of the listed GM applications, but it is still a useful benchmark if you are comparing replacement quality across major automotive brands.
Standard Motor Products is another common aftermarket route when the goal is a dependable cross-reference rather than a branded dealership part.
Is Oil Pressure Sensor Switch Worth It?
The ENA Oil Pressure Sensor Switch is worth considering if your vehicle is one of the supported GM applications and you want a replacement part anchored to clear cross-reference numbers.
Its main strength is practical fitment coverage, not a long list of extras.
If you already confirmed the part number or vehicle match, this is a sensible buy for a repair-driven purchase.
If you have any doubt about year, engine, or connector compatibility, keep looking and verify first.
In other words, worth it for confirmed fitment, not for guesswork.
