Weasch MAP Sensor 3-Pin

What to know

The three-pin connector is the clearest practical detail on this Weasch MAP sensor: matching the connection to the part already in your vehicle can help you avoid ordering a sensor that won’t plug in. It’s made of black plastic, and the package includes one sensor. The listing names a wide range of reference numbers and vehicles, including select Chevy, GMC, Buick, Cadillac, Pontiac, and other applications, so the model name alone isn’t enough to confirm fit. Keep in mind that the supplied fitment information is broad, check your vehicle’s year and the old sensor’s connector and plug against the product details before buying.

Listed reference numbers include 55573248, 12591290, 213-4681, 93192107, and 0261230282, among others. These numbers are useful when you’re replacing a failed part and have the original number available. The listing does not provide installation instructions or vehicle-specific diagnostic guidance, so treat this as a replacement-part match rather than a complete troubleshooting solution. A MAP sensor is intended for measuring manifold absolute pressure, whether replacing this one addresses a particular vehicle problem depends on the diagnosis and fit.

How to use it

This is a replacement component, not a general-purpose accessory. Before ordering, compare the connector and plug with the sensor currently installed, then check that your vehicle appears in the stated fitment information. The listing includes examples such as Chevy Silverado models from 2007–2013, GMC Sierra 1500 models from 2007–2013, and Buick Enclave models from 2008–2019. Those ranges are not a substitute for confirming the exact application for your vehicle.

After confirming the match, the sensor is intended to take the place of the corresponding MAP sensor. For instance, if you have the old part removed or can clearly see its plug, compare its three-pin connection and reference number with the listing before placing an order. The provided information does not describe installation steps, tools, or whether professional installation is needed, so don’t assume those details from the part description.

Practical tips

Start with the number printed on the old sensor if it’s readable, matching a reference number is a more specific check than relying only on a broad make-and-year list. Then compare the connector shape and plug with the product images, as the listing specifically calls out connector matching. If the number is missing, or the vehicle has more than one possible application, confirm the correct replacement through a reliable vehicle-specific parts reference before ordering.

It makes sense if you already know you need a MAP sensor and want to check a replacement against the listed cross-reference numbers and three-pin design. It might not be a great match if you’re still trying to identify the cause of a vehicle issue or can’t verify that the listed fitment applies to your exact vehicle. A more vehicle-specific buying approach is preferable when connector or application details are uncertain.

Practical doubts

What comes in the package? The listed package includes one MAP sensor.

How many pins does the connector have? The stated terminal type is three pins, compare the plug with your existing part before ordering.

Which reference numbers are listed? Examples include 55573248, 12591290, 213-4681, and 0261230282. The listing provides additional cross-reference numbers, but not every number is necessarily relevant to every vehicle.

Buying verdict

This Weasch sensor is worth considering when the reference number, three-pin connector, and vehicle application all line up with the part you need. The long fitment list may help narrow the search, but it doesn’t establish a match for every vehicle within a model-year range. If you can’t verify the connector and application, choose a more precisely confirmed replacement rather than relying on the broad compatibility claims alone.
