Bosch MAP Sensor 0261230289 for GM — OE-Equivalent Fit, Chem-Resistant Coating

The BOSCH 0261230289 Manifold Absolute Pressure (MAP) Sensor accurately measures intake air pressure to support consistent engine performance and an OE-equivalent fit.

This Bosch MAP sensor is engineered to deliver reliable air-pressure readings for engine management systems, helping the vehicle maintain fuel economy, drivability, and emissions control across a wide range of GM platforms. Built with a chemically resistant coating and modern chip technology, the unit is designed to match or exceed original equipment specifications so installation and operation integrate smoothly with your vehicle’s existing systems.

How does this MAP sensor improve engine control?

The sensor provides precise manifold pressure data to the engine control unit (ECU), which the ECU uses to adjust fuel injection and ignition timing. That real-time feedback helps the engine respond more accurately to load and throttle changes, supporting smoother acceleration and steadier idle.

• High-resolution pressure sensing for accurate ECU inputs
• Improved fuel-air mixture adjustments under varied driving conditions
• Supports consistent idle and throttle response by supplying reliable data

What makes Bosch’s design durable for the intake environment?

Bosch adds a protective coating and uses robust materials to withstand vapors and contaminants commonly found inside intake manifolds. The rugged construction and up-to-date chip design extend service life and reduce the risk of premature failure from chemical exposure.

• Special coating resists corrosive intake-ma manifold chemicals
• Sturdy housing built for vibration and heat tolerance
• Modern semiconductor components for long-term stability

Will this sensor fit my vehicle and how easy is installation?

The BOSCH 0261230289 is manufactured to match original equipment connector and mounting points for a direct swap on many Buick, Cadillac, Chevrolet, GMC, Pontiac, and Saturn models. Verifying year, engine, and OEM part compatibility with a fitment checker is recommended before purchase. Installation is straightforward for technicians and experienced DIYers because the electrical connector and bolt locations mirror OE parts.

• OE-identical connector ports and attachment points for exact fit
• Direct replacement on many General Motors vehicles (verify fitment)
• Plug-and-play installation minimizes workshop time

How does Bosch ensure performance matches or exceeds OE standards?

Bosch continuously updates sensor circuitry and manufacturing tolerances to meet evolving engine management requirements. Each MAP sensor is validated against strict quality and performance criteria to help maintain factory-level drivability, fuel economy, and emissions behavior.

• Engineered to meet or surpass original equipment specifications
• Quality control testing for consistency and reliability
• Ongoing design improvements through advanced chip technology

Who is this for? Technicians, independent repair shops, and vehicle owners who need a reliable OE-quality MAP sensor replacement for supported GM vehicles will find this Bosch unit appropriate. It’s suited for anyone wanting a direct-fit sensor with durable construction and precise pressure readings to support proper engine management. Always confirm vehicle compatibility by checking the part against your vehicle’s year, model, and engine type before ordering.
