Description

1986-1995 C4 ACDelco Manifold Air Temperature (MAT) Sensor - OEM Number(s) (15326386)

This essential component delivers precise data to your Corvette's Engine Control Module (ECM). Designed to provide real-time data on incoming air or fuel/air mixture temperature, this variable resistance sensor goes by many names: Charge Temperature Sensor, Air Charge Temperature Sensor, or Air Thermo Sensor. Crafted with accuracy and reliability in mind, this sensor ensures your engine operates at its optimal temperature range, maximizing efficiency and power output. Count on this advanced technology to fine-tune your C4's performance, delivering a driving experience that's both smooth and powerful. ACDelco GM Original Equipment sensors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. ACDelco GM Original Equipment parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles.

Common Related Engine Fault Codes/Diagnostic Trouble Codes:

Code 23 - MAT Sensor - Usually Caused by an Open Circuit
Code 25 - MAT Sensor - Usually Caused by Low Circuit Voltage

NOTE: There are 2 designs of Manifold or Air Charge Temperature Sensors used in Corvette production between 1985-1995. The sensor and signal are the same but the Packard connector style (color) changed over a period of time during 1986 production. Confirm the connector style (color) in your Corvette engine before ordering, etc. The “hamburger” shaped style (gray) was used in early style 1985-1986. The later style 1986-1995 used a “mushroom” shaped style (black) connector.
