As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used computer from a junkyard. The result is almost always the same: the vehicle won’t start, or it runs even worse than before.

It ensures all vehicle systems communicate correctly, just as the factory intended, saving you from days of headaches and diagnostic dead-ends.

Frequently Asked Questions
Do I need to do any programming to this computer?
No. This computer is shipped to you fully programmed to your vehicle’s VIN. It is ready to be installed as soon as you receive it.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your VIN, or add it to the ‘notes’ section during checkout. We must have your VIN to program the module before shipping.
Is this a difficult part to install?
For most of the compatible models, the PCM is in an accessible location (next to the air box or under the battery) and can be swapped with basic hand tools. It is critical to disconnect the vehicle’s battery before starting the installation to prevent any electrical damage.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty PCM, this part will resolve the issue. However, we always recommend having your vehicle properly diagnosed to ensure the PCM is the root cause of the problem.
What is a CASE Relearn and will I need one?
A CASE (Crankshaft Angle Sensor Error) Relearn synchronizes the new PCM with your engine’s crankshaft position sensor. In some cases, your vehicle may require this procedure after installation to clear a specific trouble code (P1336). This is a simple procedure that can be performed by most mechanics with a capable bi-directional scan tool.
