Jeep Wrangler ECU | How Do I Know If My ECU is Failing?


The engine control unit, or ECU, is one of the most important components in a vehicle. It functions as the main computer for many of the vehicle’s engine performance and drivability functions. Since it is so vital, when it fails it can cause all sorts of problems with the vehicle. Let’s take a look at some of the ways that you can figure out if your Jeep Wrangler ECU is failing.

The Check Engine Light Comes On

While the check engine light can signify a number of issues, one of those could be an issue with the ECU. If the check engine light comes on, it is important to figure out the problem and fix it immediately.

There Are Apparent Engine Issues

A main symptom of a bad or failing ECU unit is poor engine behavior. Stalling, misfiring, or performance issues, such as fuel efficiency, power, acceleration are all signs that there could be a problem with the engine control unit.

The Car Might Not Start

If your car isn’t starting, or having difficulty starting, it might be the sign of a bad ECU. If the engine control unit fails completely, it will leave the vehicle without engine management control, and will not start or run as a result.
