Restore Your Pacifica’s Performance and Reliability
Is your 2005 Chrysler Pacifica running rough, stalling unexpectedly, or refusing to start? A failing Engine Control Module (ECM) is often the hidden culprit behind these frustrating and stressful issues. You rely on your Pacifica to safely transport your family, and a faulty engine computer can compromise that reliability. This pre-programmed ECM is the definitive, hassle-free solution to get your vehicle back on the road with the performance and dependability you count on.
Common Symptoms & Your Definitive Solution
A failing ECM can manifest in various ways, often mimicking other component failures. If you’re experiencing any of the following, it’s a strong indicator that your engine computer needs replacement:
- Intermittent or Constant Stalling: The engine cuts out while driving or at a stop.
- No-Start Condition: The engine cranks but will not start, with no spark or fuel injector pulse.
- Check Engine Light (CEL): Particularly with communication codes (U-codes) or internal processor failure codes like P0601 or P0606.
- Poor Fuel Economy: A sudden and unexplained drop in MPG.
- Rough Idle and Misfires: The engine runs erratically, causing shaking and poor acceleration.
Instead of facing a costly and time-consuming trip to the dealership, this programmed 2005 Chrysler Pacifica 3.5L AWD ECM arrives at your door ready for a simple, direct installation. We handle all the complex programming so you can restore your vehicle’s brain with confidence.

From the Technician’s Bench: We had a customer with a 2005 Pacifica that had been to three different shops for an intermittent stalling problem that no one could diagnose. It would die at stoplights without warning, making it unsafe for his family. After confirming the power and grounds to the ECM were solid, we suspected an internal failure. We installed one of our pre-programmed units, and the problem vanished instantly. He called a week later, overjoyed that he could finally trust his family car again. That’s the confidence a quality 2005 Chrysler Pacifica 3.5L AWD ECM provides.
Frequently Asked Questions
Is this unit really ‘Plug and Play’?
Absolutely. We use your vehicle’s VIN to program the module before it ships. This ensures all immobilizer (security) information and vehicle-specific settings are correctly configured. All you need to do is disconnect the battery, swap the modules, and reconnect the battery. No further programming is required.
How do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield. It is crucial you provide the correct VIN during checkout.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM (such as internal processor error codes), then yes, this part will resolve the issue. However, if the codes are for other failing sensors or components (like an oxygen sensor or EGR valve), those parts will still need to be addressed. This 2005 Chrysler Pacifica 3.5L AWD ECM will ensure the vehicle’s computer is operating correctly and reading those sensors properly.
Do I need to send my old part back?
No core charge or return is required for this part. You can keep or responsibly recycle your old module.
What if my part number isn’t on your list?
The part numbers listed are the most common ones, but there may be others. As long as your vehicle is a 2005 Chrysler Pacifica with the 3.5L AWD engine, this module is the correct one for your vehicle. We program it based on your VIN, which guarantees compatibility.
