Wbsteanaten MAP Sensor Manifold Absolute Pressure Sensor 12569240 Direct-Fit — Fast Response, Heat-Resistant

The Wbsteanaten MAP Sensor 12569240 is a direct-fit manifold absolute pressure sensor that measures intake vacuum to help your vehicle's ECU adjust fuel and ignition timing accurately.

This high-precision MAP sensor replaces OE 12569240 and is built for older GM, Jeep, Pontiac and Chevy platforms — including Cherokee, Wrangler, Grand Cherokee, Grand Prix, Lumina, Astro/Safari and many C/K trucks from the 1980s through early 2000s. Designed to withstand engine-bay heat and vibration, the sensor provides stable pressure readings across a wide temperature range and fast electronic response for reliable operation in gasoline and diesel applications.

How does this MAP sensor improve engine control?

The sensor supplies the engine control unit with real-time intake manifold pressure data so the ECU can refine fuel delivery and ignition timing. Accurate pressure input helps the vehicle manage load changes and altitude variations more consistently.

• Rapid response time under 2 ms for quick signal updates
• Max error of ~3% between 0°C and 85°C for consistent readings
• Direct electrical and mounting fit for listed OE 12569240 replacements

Is this part compatible with my older GM, Jeep or Pontiac vehicle?

Wbsteanaten lists wide fitment across many GM platforms and select Jeep/Pontiac models from the 1980s–2000s. Check vehicle year, engine code and the original part number before ordering to confirm compatibility with your application.

• Common fits include Jeep Cherokee/Wrangler/Grand Cherokee models and Pontiac Grand Prix
• Covers numerous Chevrolet and GMC trucks, vans and passenger cars across listed years and engines
• Replacement for OEM part number 12569240 — verify against your existing sensor

What are the technical qualities and durability features?

This MAP sensor is engineered for automotive environments with heat-resistant materials and sealed electronics to resist moisture and vibration. The fast electronic response and low measurement error improve reliability across varying operating temperatures.

• Temperature-tolerant construction for harsh engine-bay conditions
• Sealed housing to protect sensing element from contaminants
• Designed for both gasoline and diesel engines where specified

How easy is installation and what should I check before purchase?

Installation is typically straightforward: unplug the old sensor, remove its mounting, and install the new unit in the same location using original fasteners and electrical connectors. Always confirm fitment with your vehicle details and compare the new part visually to the old sensor.

• Plug-and-play electrical connector matching OE 12569240 for most listed vehicles
• Mounts to the intake manifold or vacuum line location used by the original unit
• Confirm vehicle year, engine size and original part image before ordering

Who this is for: This Wbsteanaten MAP Sensor suits owners and mechanics restoring or maintaining classic and late-model GM, Pontiac and Jeep vehicles that require a direct-replacement 12569240 sensor. It's aimed at those who need a robust, accurate, and heat-resistant MAP sensor to restore proper engine management on vehicles from the 1980s through the early 2000s. Ideal for DIY installers, independent shops, and fleet maintenance teams who value OE-style fitment and clear compatibility listings.
