Product Details and Compatibility

The Spectra MP123 Manifold Absolute Pressure Sensor is engineered to meet OEM specifications for emission control sensors. It accurately measures the absolute pressure inside the intake manifold, providing critical data to the engine control unit (ECU) for fuel delivery and ignition timing adjustments. This sensor is compatible with a wide range of GM vehicles, including Buick models like the Century and Regal, Cadillac Allante and Seville, Chevrolet Impala and Monte Carlo, GMC K2500 and P3500, Oldsmobile Cutlass and Delta 88, and Pontiac Firebird and Bonneville. Using the correct MAP sensor ensures your vehicle’s engine runs efficiently and meets emission standards.

Common Applications and Problem Resolution

  • Helps resolve rough idling and engine stalling issues
  • Improves fuel economy by providing accurate pressure data
  • Reduces engine hesitation and poor acceleration
  • Prevents check engine light triggers related to manifold pressure faults
  • Supports proper emission control system operation

Installation Notes and Tips

Installation of the Spectra MP123 sensor requires basic mechanical skills and standard hand tools. Before installation, ensure the engine is cool and disconnect the battery to prevent electrical shorts. Locate the existing MAP sensor on the intake manifold, carefully disconnect the electrical connector, and remove the mounting screws. Install the new sensor in the same orientation, secure it firmly, and reconnect the electrical connector. After installation, clear any diagnostic trouble codes and verify proper sensor operation with a scan tool.

Quality Assurance and Warranty

Manufactured to meet industry standards, the Spectra MP123 Manifold Absolute Pressure Sensor undergoes rigorous quality control testing to ensure reliability and accuracy. This part is backed by a limited warranty covering defects in materials and workmanship, providing confidence in its long-term performance on compatible Buick, Cadillac, Chevrolet, GMC, Oldsmobile, and Pontiac vehicles.
