How to Fix Limp Mode in Your Chevy Silverado

AvatarByCarl Frisch

Limp Mode is a diagnostic feature found in many Chevy Silverado vehicles. It is designed to limit the vehicle’s power output when certain conditions are met. When engaged, the engine may fail to respond to acceleration and the vehicle will not exceed a certain speed, regardless of the amount of throttle applied. This feature is designed to keep the engine from being damaged due to an over-revving or overheating condition. Common causes for limp mode include faulty sensors, dirty air filters, low engine coolant levels, or clogged fuel filters. If limp mode is engaged, it can be cleared by restarting the engine or by addressing the underlying issue that caused it to activate in the first place.
