Expert Insight from a 20-Year Veteran Technician
I’ve seen countless vehicle owners chase their tails replacing perfectly good sensors, spark plugs, and coils, only to find the root issue was the ECM all along. A classic indicator is a set of bizarre, unrelated error codes that don’t point to a single component failure. This ‘confusion’ in the system often originates from a failing processor in the ECM. Installing a properly programmed 2006 Pontiac Montana engine control module doesn’t just clear the codesโit restores the logical foundation of your entire engine management system.
