Detailed Description

The Spectra MP173 is a manifold absolute pressure sensor engineered to match OE requirements for fit, form, and function. It uses a black plastic housing, an oval connector shape, and a 4-terminal pin-style interface to support proper electrical connection and sensor integration. This part number, MP173, is used across multiple GM platforms, including Chevrolet Camaro, Cadillac XT5, and GMC Acadia applications. If you are replacing a failed MAP sensor on a Chevrolet Colorado, Cadillac CTS, or Buick Regal Sportback, MP173 provides a direct replacement option built around the original equipment specification.

This part cross-references Standard Ignition AS682 for the same application.

What It Is Used For

• Replacing a faulty manifold absolute pressure sensor
• Restoring accurate intake manifold pressure signal output
• Addressing drivability issues tied to incorrect sensor readings
• Correcting engine management faults related to MAP sensor performance
• Supporting proper fuel and ignition control inputs

Installation Notes and Tips

Verify connector shape, terminal count, and port configuration before installation. Confirm application coverage by year, make, and model, since MP173 is used across multiple GM platforms. Match the replacement sensor to the original part number MP173 and compare the connector style to the removed unit before installation.
