End Your Engine Troubles and Get Back on the Road
Is your Chevrolet Cobalt, HHR, or Pontiac Pursuit suffering from a persistent check engine light, erratic shifting, a rough idle, or even a no-start condition?

This replacement PCM, programmed specifically for your car’s VIN, is the definitive, hassle-free solution to restore your vehicle’s reliability and performance.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of problems that are often misdiagnosed as bad sensors or other components. If you’re experiencing any of the following, a failing engine computer is the likely culprit:
- Persistent Check Engine Light (CEL) with communication error codes (U-codes) or multiple sensor circuit codes.

Frequently Asked Questions
Do I need to program this unit myself?
No. This is the main benefit of our service. We program the PCM using the VIN you provide before we ship it. It will arrive ready for installation, requiring no further programming from a dealer or mechanic.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will send you a message requesting your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for correct programming.
Will this work with my car’s anti-theft system?
Yes. After installation, you will need to perform a security relearn procedure, also known as a CASE relearn. This is a standard process that pairs the new PCM to your vehicle’s security system. This procedure can typically be done without special tools and instructions are widely available online or in your vehicle’s service manual.
