There are numerous diagnostic trouble codes (DTCs) that could trigger the check engine light (CEL) on your 2017 Jeep Wrangler. I can offer some general insights, but you'll need to obtain the specific code or share some symptoms for me to provide more assistance. Essentially, the CEL illuminates when the onboard diagnostic system, typically OBD-II, detects a problem with the engine, transmission, or evaporative system. Common accompanying issues with the illuminated CEL include rough engine performance, misfires, power loss, sluggish throttle response, overheating, smoking from the exhaust, and excess noise. While a faulty sensor is often to blame, more severe problems could be at play, so it's crucial to retrieve the code. AutoZone can usually read the code for you at no cost, which is recommended for further diagnosis.
