Product Details

This MAP sensor is used in systems that monitor intake manifold pressure so the engine control module can calculate load and adjust fuel and ignition strategy. If you are replacing a faulty Walker 225-1322 sensor on a vehicle that uses this application, it is a direct-fit style engine sensor replacement for accurate pressure feedback. It is also referenced in the aftermarket under related numbers such as Bosch 15122 and Standard Ignition AS625.

Common Issues It May Resolve

• Rough idle caused by incorrect manifold pressure readings
• Hard starting related to inaccurate engine load data
• Check engine light triggered by MAP sensor faults
• Poor throttle response from unstable sensor output
• Fuel trim problems caused by incorrect intake pressure input

Installation Notes and Tips

Verify the connector style, mounting location, and calibration requirements before installation. Inspect the vacuum source, intake plumbing, and wiring harness for damage or leaks before replacing the sensor. After installation, clear diagnostic trouble codes and confirm stable readings with a scan tool.
