Detailed Description

The MAP sensor measures manifold pressure so the engine control system can calculate load and adjust fuel delivery and ignition timing. When the sensor signal is inaccurate, drivability and emissions performance can suffer. Walker Products 225-91026 is built for the 1989 Pontiac Firebird application and supports proper sensor replacement in the emission control system.

This part cross-references Standard Ignition AS210 for the same application. If you are searching for a 1989 Pontiac Firebird manifold absolute pressure sensor, Walker Products FSK 225-91026 provides the connector style and terminal configuration needed for a direct replacement.

What It Helps Address

• Rough idle caused by incorrect manifold pressure input
• Hesitation or poor throttle response
• Fuel mixture issues related to faulty MAP sensor readings
• Check engine light conditions tied to sensor signal faults
• Emission control performance problems on the Pontiac Firebird

Installation Notes and Tips

Verify connector shape, terminal count, and harness length before installation. Confirm the sensor location and electrical connection on the 1989 Pontiac Firebird, and inspect the mating connector for corrosion, bent terminals, or damaged wiring before replacing the part. Clear diagnostic trouble codes after installation and confirm stable idle and throttle response during a road test.
