## Description

GM Genuine Parts Engine Control Modules are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These modules regulate various parts of your vehicle's engine by receiving input from sensors and additional modules and then referencing that information back to other sensors, modules, and areas of the vehicle. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Review: Genuine OEM Fit and Works Exactly as Expected - If you’re replacing an Engine Control Module, going with a genuine GM part is the safest route and this one worked exactly as it should. The module arrived properly packaged and in good condition. Fitment was correct for the specified vehicle, and once programmed, it functioned without issues. No warning lights, no communication errors, and the vehicle ran smoothly. With critical components like an ECM, reliability matters more than saving a few dollars on aftermarket options. OEM parts eliminate compatibility concerns and reduce the risk of drivability problems. Keep in mind that most vehicles will require proper programming or flashing after installation, so this is not necessarily a plug-and-play part for everyone. Make sure you have access to the right tools or professional programming if needed. Overall, this is a genuine, reliable replacement that performs exactly as intended. If your vehicle calls for this part number, it’s a solid choice. 5 stars.
Review: Best Price Around! - desertcart had the best price I could find on a genuine AC DELCO ECM. Shipping was fast, only took two days. I brought my truck and this part to my local GM dealer and they programmed it no problem.
