Expert Insight: The Heart of the 4.0L
As a technician with over 20 years of experience, I can tell you the Jeep 4.0L inline-6 is a legend for a reason—it’s tough and built to last. But even the toughest engines rely on a healthy ‘brain’ to manage everything from fuel delivery to spark timing. The original ECMs in these WJs are now over two decades old, and electronic components simply wear out. Replacing a failing unit isn’t just about fixing a problem; it’s about preserving the life and soul of your vehicle. A properly functioning 2001 Jeep Grand Cherokee ECM ensures this legendary engine performs as it was designed to, giving you many more years of reliable service.
