ACDelco Professional 213-4434 MAP Sensor Review
By SellySell Editorial Team | Last updated: June 11, 2026
The ACDelco Professional 213-4434 is a replacement MAP sensor for vehicles that use the matching fitment and OEM reference number. A MAP sensor measures intake manifold pressure and sends that signal to the engine control module. The ECM uses that signal for fuel and ignition calculations.
This review uses only the product details provided in the supplied article HTML. Live Amazon verification was not performed, so buyers should confirm current fitment, connector shape, and OEM part number on the Amazon page or with a parts catalog before ordering.
Verdict
The ACDelco Professional 213-4434 is best suited for buyers who need a compact flange-mount MAP sensor and have confirmed that OEM number 19236265 matches their vehicle. It is a practical replacement choice when the connector, mounting style, and application all match.

What Is This Product?
The ACDelco Professional 213-4434 is an intake manifold absolute pressure sensor. It is designed to read pressure changes inside the intake manifold and send that information to the vehicle computer.
A correct MAP signal helps the engine control module calculate fuel delivery. If the old sensor is faulty, the vehicle may show rough idle, poor throttle response, bad fuel trim, or an engine code. A replacement sensor can help only when the original sensor is the real cause of the problem.
Who It Is For
This sensor is for technicians and DIY owners who have confirmed that ACDelco 213-4434 or OEM number 19236265 fits their vehicle.
It is also a sensible choice for buyers who want a compact flange-mount MAP sensor and prefer a part from the ACDelco Professional line.
Who Should Skip It
Skip this part if your vehicle does not match the OEM reference number, connector style, mounting pattern, or vacuum port layout. MAP sensors can look similar but use different calibration or connector designs.
You should also skip it if you have not diagnosed the issue yet. Rough idle and poor throttle response can come from vacuum leaks, wiring faults, dirty throttle bodies, bad grounds, or other sensors.

- OEM reference number 19236265 listed in the supplied article
- Compact 3.6 x 2.2 x 1.7 inch size listed in the supplied article
- Light 0.88 ounce listed weight
- Flange-mount design
- Electronic output for engine control module input
Installation and Compatibility Notes
Fitment is the most important buying step. Before ordering, match the vehicle application, OEM number, connector pin layout, mounting holes, and port design.
During installation, inspect the gasket or seal, connector terminals, connector lock, and nearby vacuum lines. A weak seal or damaged connector can cause the new sensor to give poor readings even when the part itself is working.
Use the manufacturer torque specification where available. If no specification is available, avoid over-tightening because small plastic sensor housings and flanges can crack or distort.
Real-World Use
A working MAP sensor supports stable fuel trim and predictable drivability. On a compatible vehicle, replacing a failed sensor may help restore smooth idle, cleaner throttle response, and better engine control.
These results depend on correct diagnosis. If the vehicle has a vacuum leak, wiring problem, or ECU issue, replacing only the MAP sensor may not fix the symptom.
Pros and Cons
Pros
- Compact flange-mount design can fit tight engine bay locations when the application is correct
- ACDelco Professional model is easy to identify by part number 213-4434
- OEM reference number 19236265 gives buyers a clear fitment detail to check before purchase
Cons
- Vehicle fitment must be checked carefully before ordering
- The supplied article gives limited verified detail about included accessories or warranty terms
- A new MAP sensor will not fix drivability problems caused by leaks, wiring faults, or other engine issues
Is It Worth the Price?
The ACDelco Professional 213-4434 can be worth considering if it matches your vehicle and your old MAP sensor has been diagnosed as faulty. The value comes from buying the correct part once, not from guessing.
Before buying, compare the part number, connector, mounting style, and return terms on the current Amazon listing. Do not rely on price or availability claims from older reviews because those details can change.
Alternatives to Consider
If this part does not match your vehicle, compare it with similar MAP sensor options from GM Genuine Parts, Delphi, and Standard Motor Products. Use those names only as fitment research starting points. Always match the exact vehicle application and OEM reference number before choosing an alternative.
Frequently Asked Questions
Can This MAP Sensor Be Recalibrated or Require ECU Relearning?
The sensor itself is normally replaced as a fixed-calibration part. Some vehicles may need an ECU reset, idle relearn, or drive cycle after installation. Check the service manual for your exact vehicle.
Does It Affect Emissions Testing or OBD-II Readiness?
Yes, a MAP sensor can affect fuel trim and OBD-II monitor readiness. After replacement, the vehicle may need drive cycles before all monitors show ready. A correct repair should also clear the related fault cause, not just the code.
What Is the Expected Lifespan Under Typical Driving Conditions?
The supplied article suggests 5 to 10 years under typical driving conditions, but lifespan depends on heat, vibration, intake condition, electrical connection quality, and maintenance. Treat that range as a general estimate, not a guarantee.
Is There a Difference Between OEM and ACDelco Packaging?
Packaging can vary by seller, distribution channel, and product line. Check the current listing photos, seller details, and part labels when the package arrives.
Are There Any Known Intermittent Electrical Connector Issues?
The supplied article does not provide verified evidence of a widespread connector issue. Still, inspect the vehicle-side connector for corrosion, loose pins, broken locks, or oil contamination before installing the new sensor.
Final Verdict
The ACDelco Professional 213-4434 MAP sensor is a focused replacement part for compatible vehicles. Its biggest strengths are clear part identification, compact size, and a listed OEM reference number that buyers can use for fitment checks.
Buy it only after confirming compatibility with your vehicle. If the part number, connector, and mounting style match, it can be a practical replacement for a diagnosed MAP sensor fault.
