How the PS20067 Supports Engine Performance

The Delphi PS20067 MAP sensor measures manifold pressure so the engine control module can calculate air density and adjust fuel delivery, ignition timing, and load calculations. Delphi validates and calibrates its sensors to OE standards, helping maintain accurate readings across daily driving, towing, and stop-and-go operation. This part cross-references Standard Ignition AS428 for the same application.

Common Issues This Sensor May Address

• Rough idle caused by incorrect manifold pressure data
• Hesitation or poor throttle response under acceleration
• Check engine light related to MAP sensor signal faults
• Hard starting or unstable air-fuel calculations
• Reduced drivability from inaccurate engine load readings

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. The PS20067 uses a bolt-on design with a single port and rectangular 1-connector layout, so matching the OE connector and sensor orientation is important. Inspect the intake passage and electrical connector for contamination, corrosion, or damaged pins before replacing the sensor.
