Spectra MP138 Manifold Absolute Pressure Sensor

Spectra MP138 Manifold Absolute Pressure Sensor

The Spectra MP138 manifold absolute pressure sensor is built for direct replacement service on a wide range of Hyundai and Kia vehicles. It is engineered to meet or exceed OE specifications for fit, form, and function, helping restore accurate intake manifold pressure signal output for proper engine management.

• Manifold absolute pressure sensor for emission control and engine management systems
• OE-style fit, form, and function for straightforward replacement
• Compatible with many Hyundai Sonata, Santa Fe, Azera, Veracruz, and Kia Optima, Sorento, Sedona applications
• Cross-references Delphi PS10149 and Standard Ignition AS197
• Part number MP138 for catalog and service verification

Detailed Product Information

This Spectra MAP sensor is used to monitor manifold pressure so the engine control system can calculate load and adjust fuel delivery and ignition timing. Accurate sensor input is important for drivability, emissions performance, and consistent engine operation. The MP138 is a practical replacement choice for Hyundai Genesis, Entourage, XG350, XG300, and Kia Amanti, Magentis, Rio, Rio5, and Rondo applications where the original sensor has failed or is reading outside specification.

Common Symptoms It Can Address

• Check engine light related to manifold pressure or sensor circuit faults
• Rough idle or unstable engine speed
• Hesitation, poor throttle response, or reduced acceleration
• Hard starting or inconsistent fuel control
• Emissions test failure tied to sensor input errors

Installation Notes

Verify connector style, mounting location, and engine application before installation. Compare the old sensor to the MP138 and confirm the vehicle listing for your exact year, make, and model. After installation, clear diagnostic trouble codes and confirm normal sensor readings with a scan tool.

Quality Assurance

Spectra designs this manifold absolute pressure sensor to meet or exceed OE specifications for fit, form, and function. The MP138 is intended as an OE-style replacement for service work on Hyundai and Kia platforms, including 1999-2014 model coverage across the listed applications.
