★ Top Answer
The diagnostic trouble code P15A1 on the Chevrolet Equinox (and other vehicles with OBD-II) signifies a problem with the "Fuel Economy Mode Switch Performance." This issue can be caused by a faulty fuel economy mode switch, a damaged wiring harness, or a weak electrical connection. Thankfully, this specific code indicates that the problem is likely with the fuel economy mode switch itself. This switch is responsible for toggling between "Eco" mode, which sacrifices power for better fuel efficiency. If fuel efficiency isn't a top priority for you, replacing this component may not be critical, especially considering the potentially high cost of replacement.
