Detailed Description

Delphi PS20117 is a manifold absolute pressure sensor engineered for vehicles that rely on precise intake manifold pressure data for fuel and ignition control. The sensor uses a 5V signal design, pin terminals, and a single male connector to support direct replacement service on select Ford models. With OE development and validation methods, Delphi focuses on consistent output that matches the needs of modern engine management systems.

Compatible With select Ford Transit-150, Transit-250, Transit-350, Transit-350 HD, F-150, F-250 Super Duty, F-350 Super Duty, Fiesta, Focus, and Escape applications across the listed model years. The Delphi PS20117 is also referenced by Walker Products 225-1097.

What It Helps Address

• Erratic engine load signal readings
• Check engine light concerns related to MAP sensor performance
• Rough idle caused by inaccurate manifold pressure input
• Fuel delivery and air-fuel ratio control issues tied to sensor output
• Driveability problems from inconsistent intake pressure data

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a bolt-on design with a black rectangular connector and 3 terminals, so matching the original configuration is important for proper fitment. Confirm the vehicle application by year, make, and model before ordering, especially on Ford Transit, F-150, Fiesta, Focus, and Escape platforms.

For best results, inspect the connector, wiring, and intake passage for damage or contamination before replacing the sensor. Clear diagnostic trouble codes after installation and confirm the repair with a road test or scan tool data review.

Quality Assurance

Delphi sensors are tested and calibrated to OE standards and supported by stringent development and validation methods. That focus on measured output and application-specific accuracy helps reduce repeat repairs and supports dependable service life.
