Restore Your Vehicle’s Performance and Reliability
Is your Chevrolet HHR, Cobalt, or Pontiac Pursuit suffering from frustrating issues like stalling, erratic shifting, or a persistent Check Engine Light?

- Check Engine Light: Specifically for internal module failure codes like P0601, P0602, P0603, P0604, or P0606.
- No-Start Condition: The engine cranks but refuses to start due to a lack of fuel or spark commands from the PCM.
- Poor Performance: Unexplained drops in fuel economy, hesitation during acceleration, or a general lack of power.
- Erratic Shifting: Harsh or delayed gear changes in automatic transmissions.
- Engine Stalling: The engine randomly shuts off while driving or at idle.

Expert Insight: The Critical Role of VIN Programming
Why can’t you just use a module from another car? Your vehicle’s PCM is its central brain, and it’s digitally tied to the unique Vehicle Identification Number (VIN). This link governs critical systems like the anti-theft immobilizer (VATS), fuel injector pulse width, and transmission shift points. Our meticulous VIN-programming process ensures this new computer is a perfect digital match for your car. This crucial step prevents compatibility conflicts and ensures your vehicle operates precisely as GM engineers intended, saving you from the frustrating and costly cycle of follow-up repairs that often comes with using a non-programmed part. Getting the programming right is the key to a successful, one-time fix for your 2006 Chevy HHR PCM 12597329.
