The Powertrain Control Module (PCM) on a 2002 Chevy S-10 is typically located
under the hood, near the firewall, on the driver's side. However, it's not always in the exact same spot across all models. It's often mounted to the inner fender well or on a bracket attached to the firewall itself.
To be certain, consult your owner's manual or a repair manual specific to your 2002 Chevy S-10. These manuals will have diagrams showing the exact location. You can also search online for "2002 Chevy S-10 PCM location" along with images for visual confirmation.
