Is your trusty S10 or Sonoma suddenly running rough, stalling, or refusing to start? A failing Powertrain Control Module (PCM) can bring your workhorse to a halt, causing endless frustration and costing you valuable time. This isn’t just an inconvenience; it’s a disruption to your daily life. We have the reliable, straightforward solution. This PCM, part number 12202203, is the definitive fix for your truck, arriving at your door fully programmed to your specific Vehicle Identification Number (VIN) and ready for a simple installation.
Common Symptoms & Your Solution
If you’re experiencing issues like a persistent check engine light, poor fuel economy, erratic shifting, or a complete no-start condition, your original PCM is the likely culprit. Diagnostic Trouble Codes (DTCs) such as P0601, P0602, P0604, or P0606 often point directly to an internal module failure. Instead of paying for expensive diagnostics and programming at a dealership, this unit provides a direct path to getting your truck back in service. Our expertly programmed 2000-2003 S10 Sonoma 2.2L PCM restores factory performance and communication, eliminating the guesswork and getting you back on the road with confidence.

Expert Insight: Back on the Job
“We had a local contractor, Mark, with an ’02 Sonoma that he depends on for his painting business. His truck was stalling intermittently, making him late for jobs and costing him money. The shop quoted him over a thousand dollars for a new computer and programming. He was about to give up on his trusty truck when he found us. We sent him this pre-programmed 2000-2003 S10 Sonoma 2.2L PCM. He installed it himself in under an hour on a Saturday morning and was back to work on Monday, problem-free. It’s not just about selling a part; it’s about providing a real-world solution that keeps hardworking people moving forward.”
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your truck.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is very straightforward. The PCM is located in the engine compartment. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old unit to swap in the new one. No special programming tools are required on your end.
Will this fix my check engine light?
If the check engine light is on due to a fault within the original PCM (like a P0601 code), this replacement unit will resolve the issue. However, if the light is on for another reason (e.g., a bad oxygen sensor), that separate issue will still need to be addressed.
Does this PCM require any additional setup after installation?
In some cases, a security relearn procedure may be necessary, which can typically be done without special tools by following a simple key-on/key-off sequence. We include instructions for this common procedure.
Is this the correct part for my 4.3L V6 S10?
No, this specific 2000-2003 S10 Sonoma 2.2L PCM is only for models equipped with the 2.2L 4-cylinder engine. Please verify your engine size and part number before ordering to ensure compatibility.
