Common Symptoms & Your Solution
A failing ECM can cause a wide range of confusing problems. If you’re experiencing any of the following, it’s highly likely your engine computer is the culprit:
- No-Start Condition: The engine cranks but refuses to start, or starts and immediately stalls.
- Check Engine Light: You may see diagnostic trouble codes (DTCs) like P0601 (Internal Control Module Memory Check Sum Error), P0605, or P0606.
- Poor Performance: Noticeable loss of power, rough idling, poor fuel economy, or hesitation during acceleration.
- Communication Errors: Your mechanic’s scan tool is unable to communicate with the ECM.
- Intermittent Stalling: The vehicle shuts off unexpectedly while driving, often without warning.

Expert Insight: The Chrysler SKIM System
Many PT Cruiser owners don’t realize that a generic, un-programmed computer simply will not work. Chrysler vehicles of this era use a Sentry Key Immobilizer Module (SKIM) that requires the ECM to have the correct VIN programmed into it to allow the engine to start. Our process handles this for you. We flash your VIN before shipping, so the new ECM is immediately recognized by your car’s security system, making the installation as simple as swapping the part.
Frequently Asked Questions
Is this module truly plug and play?
Absolutely. We use the VIN you provide during checkout to program the computer’s software to match your vehicle’s specific configuration. This ensures it works seamlessly with your existing keys and security system without any additional steps required.
How do I know for sure that my engine computer is the problem?
While the symptoms listed above are strong indicators, the most definitive way is a professional diagnosis. A common sign is the presence of a P0601 trouble code, which specifically points to an internal ECM failure. Another key indicator is when a scan tool cannot communicate with the 2003 PT Cruiser engine computer at all.
Will this fit my PT Cruiser with a turbo?
No, this specific module is for the 2003 PT Cruiser with a non-turbo engine and an automatic transmission (AT). Please verify your vehicle’s options before ordering to ensure compatibility.
What information do you need from me to program it?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the 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.
My original part number is slightly different. Will this still work?
Yes, this unit is a direct replacement for several part numbers. It is compatible with the following: 05033071AF, 05033071AG, 05033071AH, 05033071AI, 05033071AJ, 05033071AK, and 05033069AG. As long as your original part number is on this list, this module will function perfectly.
