If you are searching for a Map Sensor For 1996 Jeep Grand Cherokee, the part you are most likely looking for is the MAP sensor, short for Manifold Absolute Pressure sensor. It is a small engine-management component, but a failing sensor can create surprisingly noticeable problems.

A-Premium Manifold Pressure MAP Sensor

The A-Premium sensor is one of the easiest choices to consider if your 1996 Jeep Grand Cherokee has the 4.0L inline-six gasoline engine. Amazon’s listing specifically identifies compatibility with the 1996 Grand Cherokee L6 4.0L.
It is designed as a direct replacement rather than a universal sensor, which is exactly what I would look for on an older Jeep. With a vehicle this age, minimizing connector or mounting differences is much more important than buying a sensor simply because it is inexpensive.
Pros
- Directly listed for the 1996 Jeep Grand Cherokee 4.0L
- Vehicle-specific replacement design
- Straightforward option for a stock engine
- Easy Amazon availability
Cons
- You still need to verify the original sensor number
- Not a reason to skip diagnosing wiring or vacuum problems
My Opinion
This would be my first option for a stock 4.0L Grand Cherokee. The compatibility information is clear, and that reduces one of the biggest problems when buying replacement sensors online: ending up with a part that looks right but does not match the Jeep.
OSKYUO 56028303 MAP Sensor

The OSKYUO MAP sensor is especially interesting for owners who have already checked their original part and found 56028303. Amazon lists this sensor for the 1996 Jeep Grand Cherokee 4.0L, along with several related Jeep applications.
Matching the OE reference number makes shopping much easier because you are not relying on the vehicle name alone. That matters with 1990s Jeeps, where different engines can use different engine-management parts.
Pros
- References OE number 56028303
- Listed for 1996 Grand Cherokee 4.0L
- Three-terminal replacement configuration
- Good choice when matching by part number
Cons
- Fitment should still be checked before ordering
- Intended applications should not be assumed across every Grand Cherokee engine
My Opinion
I like this one most when you can physically inspect the old sensor first. If 56028303 appears on your existing part or matches your verified replacement number, the OSKYUO becomes a much more confident purchase than choosing by appearance alone.
Evan-Fischer MAP Sensor

Evan-Fischer offers another replacement MAP sensor listed on Amazon for 1996 Jeep Cherokee and Grand Cherokee applications. The listing identifies a three-pin configuration and specifically references 1996 Jeep compatibility.
This is the type of replacement I would consider when the goal is simply to return an older daily-driven Jeep to normal operation without paying for features that a basic MAP sensor does not need.
Pros
- Designed as an automotive replacement sensor
- Three-pin connector configuration
- Amazon listing includes 1996 Jeep applications
- Straightforward replacement option
Cons
- Engine-specific fit should be confirmed
- Connector shape should be compared with the original before purchase
My Opinion
For a nearly 30-year-old Jeep, simple fitment matters more than fancy packaging. This Evan-Fischer unit makes sense as a practical replacement, but I would still compare the connector, engine size, and original part number before clicking Buy Now.
AISIN AFTERMARKET PRSCH-00302 MAP Sensor

The AISIN AFTERMARKET PRSCH-00302 is another option specifically listed for the 1996 Jeep Grand Cherokee. Amazon identifies Grand Cherokee 1996 compatibility and references the L6 4.0L application.
This makes it an appealing choice for buyers who prefer to compare established automotive parts brands rather than shopping only by the lowest price.
Pros
- Specifically listed for 1996 Jeep Grand Cherokee
- Suitable option for the 4.0L application
- Clear vehicle compatibility information
- Useful alternative to budget-focused replacements
Cons
- May cost more than basic generic sensors
- Original part and connector should still be checked
My Opinion
If I were choosing between several nearly identical sensors and wanted to prioritize the manufacturer rather than simply getting the cheapest one, this AISIN option would be high on my list. Clear model-specific fitment is another advantage.
Buyer’s Guide: 3 Key Factors To Consider
Engine Compatibility
Do not buy a MAP sensor only because the listing says “1996 Jeep Grand Cherokee.”
The engine matters.
If your Jeep has the 4.0L inline-six, look for a listing that specifically names the 1996 Grand Cherokee 4.0L. Several of the products above do exactly that.
If you have another engine, confirm compatibility independently before ordering.
OE Part Number And Connector
Comparing part numbers is one of the safest ways to narrow your choices.
For several 1996 Jeep 4.0L applications, Amazon listings reference 56028303.
Look at your old sensor before buying. Compare:
- OE or interchange number
- Electrical connector shape
- Number of terminals
- Mounting points
- Engine size
- Vehicle trim and production year
Five minutes of checking can save you the trouble of returning the wrong sensor.
Diagnose Before Replacing
A trouble code involving manifold pressure does not automatically prove that the MAP sensor itself has failed.
Damaged wiring, a loose electrical connector, a vacuum leak, or another engine-management problem can sometimes create similar symptoms. Inspect the connector and related components before replacing parts at random.
If you are unsure about the diagnosis, using an appropriate scan tool or having the vehicle checked by a qualified technician can prevent unnecessary parts replacement.
Frequently Asked Questions About Best Map Sensor For 1996 Jeep Grand Cherokee
Is A Mat Sensor The Same As A MAP Sensor?
For this Jeep-related search, “mat sensor” is commonly being used when the intended part is the MAP sensor, or Manifold Absolute Pressure sensor. Amazon’s relevant 1996 Jeep Grand Cherokee listings are sold as MAP sensors.
What Does The MAP Sensor Do On A 1996 Jeep Grand Cherokee?
The MAP sensor measures intake-manifold pressure. The engine-control system uses that information as part of its calculations for engine operation.
When the sensor or its circuit has a problem, you may notice poor running, hesitation, difficult starting, or a check-engine light.
Which MAP Sensor Fits A 1996 Jeep Grand Cherokee 4.0?
The A-Premium, OSKYUO, and AISIN PRSCH-00302 listings reviewed above specifically identify 1996 Jeep Grand Cherokee 4.0L compatibility.
Still, compare the old sensor and part number before ordering.
Is 56028303 The Correct MAP Sensor Number?
The 56028303 number appears on multiple current replacement listings for 1996 Jeep Cherokee and 1996 Grand Cherokee 4.0L applications.
Because vehicle configurations can vary, verify it against your existing sensor or vehicle-specific parts information before purchase.
Can I Replace The MAP Sensor Myself?
For someone comfortable with basic automotive repairs, replacing an accessible plug-in sensor may be fairly straightforward. Work with the engine switched off and follow the correct procedure for your Jeep.
If you are not sure where the sensor is located or whether it is actually faulty, diagnosis should come before replacement.
Should I Buy The Cheapest MAP Sensor?
Not automatically.
Correct fitment, connector design, OE cross-reference numbers, construction quality, and seller support matter more than saving a few dollars. A cheap sensor is not good value if it produces incorrect readings or does not fit your Jeep properly.
Final Verdict: Which One Should You Buy?
For a Mat Sensor For 1996 Jeep Grand Cherokee, start by confirming that what you actually need is the MAP sensor and then check your engine size.
For a 1996 Grand Cherokee with the 4.0L inline-six, the A-Premium Manifold Pressure MAP Sensor is my best overall choice because Amazon specifically lists that vehicle and engine combination.
If matching the original number is your priority, the OSKYUO 56028303 MAP Sensor is worth a close look because its listing clearly references 56028303 and the 1996 Grand Cherokee 4.0L.
The AISIN AFTERMARKET PRSCH-00302 is another strong choice for buyers who prefer a brand-focused replacement, while the Evan-Fischer MAP Sensor offers another straightforward Amazon-listed alternative.
Whichever sensor you choose, do not rely on appearance alone. Match the engine, connector, and original part number first. That small check is the best way to avoid ordering the wrong sensor for an older Grand Cherokee.
