Detailed Description

Delphi PS20110 is a manifold absolute pressure sensor engineered for vehicles that use MAP data to manage engine performance. Delphi validates its sensors through OE-focused development and calibration processes, helping ensure the sensor delivers accurate pressure readings that the engine control system can use consistently. This part cross-references Standard Ignition AS339 for the same application.

For Ford Escape and Mercury Mariner models in the 2005-2008 range, the PS20110 offers a direct-fit replacement format with a 1.0 to 16.0 maximum pressure reading range, 1 connector, 3 ports, and a male connector/terminal layout. The part number PS20110 is a practical match for drivers and technicians replacing a faulty MAP sensor on these applications.

Common Problems This Part Can Address

• Erratic engine idle caused by incorrect manifold pressure input
• Check engine light related to MAP sensor circuit or signal faults
• Hard starting or rough running tied to inaccurate load sensing
• Poor throttle response from unstable intake pressure readings
• Fuel mixture issues when the engine control module receives incorrect MAP data

Installation Notes and Tips

Confirm connector shape, terminal count, and mount style before installation. The PS20110 uses a 3-pin, male connector with an oval housing and bolt-on mounting, so matching the original sensor configuration is important. Inspect the intake manifold port and electrical connector for contamination, corrosion, or damage before installing the new sensor.

After replacement, clear diagnostic trouble codes and verify engine operation at idle and under load. For fitment verification, use the vehicle application details for 2005-2008 Ford Escape and 2005-2008 Mercury Mariner.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and are tested and calibrated to OE standards to support accurate readings and consistent performance. The PS20110 is a standard replacement MAP sensor for select Ford Escape and Mercury Mariner applications.
