Get Your Wrangler Back on the Trail, Fast.
There’s nothing more frustrating than a Jeep that won’t run right. Whether you’re dealing with a no-start condition, a rough idle that shakes the whole vehicle, or a check engine light that just won’t go away, a faulty Engine Control Module (ECM) can bring your adventures to a dead stop. This isn’t just an inconvenience; it’s keeping you from the freedom your Wrangler was built for. We get it. That’s why we offer a straightforward, reliable solution: a pre-programmed 2005 Jeep Wrangler 2.4L Engine Computer that gets you back in the driver’s seat without the hassle and expense of a dealership visit.
Common Symptoms & Your Solution
If your 2.4L Wrangler is experiencing any of the following issues, a failing ECM is the most likely culprit:
- Sudden stalling or intermittent shutdowns
- Complete no-start condition (engine cranks but won’t fire)
- Poor fuel economy and loss of power
- Check Engine Light with communication error codes (like U0100)
- Erratic behavior from gauges or other electronics
- False sensor codes that return even after replacing the sensor
This unit is the definitive solution. It arrives at your door fully programmed to your Jeep’s specific Vehicle Identification Number (VIN) and mileage. It’s a true plug-and-play fix designed to restore your vehicle’s performance and reliability from the moment you install it.

Expert Insight: The Grounding Point Check
“Before you condemn your old ECM, take five minutes to check the main grounding points on your Wrangler’s engine block and firewall. On the TJ platform, a corroded or loose ground is a common culprit for bizarre electrical issues that mimic a failed computer. A simple cleaning with a wire brush can sometimes solve the problem. However, if your grounds are clean and tight and the symptoms persist, you can be confident that replacing the 2005 Jeep Wrangler 2.4L Engine Computer is the correct next step to a permanent fix.”
Frequently Asked Questions
Is this ECM truly ‘Plug and Play’?
Absolutely. We use the VIN you provide during checkout to program the module with your vehicle’s exact software and security information. Once it arrives, you simply install it, and it will function immediately with no further programming required.
What information do you need from me?
We need your vehicle’s 17-digit VIN (Vehicle Identification Number) and current mileage. You can typically find the VIN on your driver’s side dashboard (visible through the windshield) or on your vehicle’s registration or insurance card.
Where is the ECM located on my 2005 Wrangler?
On the 2005 Jeep Wrangler, the Engine Control Module is located in the engine bay, mounted to the firewall on the right-hand (passenger) side.
Will this fix my Check Engine Light?
If the Check Engine Light is on due to an internal failure of the original computer, then yes, this part will resolve the issue. It’s always recommended to have the codes scanned first to ensure the problem isn’t a separate sensor or wiring issue.
Does this computer work with an automatic transmission?
No. This specific module is programmed for models equipped with the 2.4L engine and a manual transmission (MT) only. It is not compatible with automatic transmission vehicles.
