Jeep Renegade engine light on with normal engine performance on Jeep Renegade

Some Jeep Renegade owners report experiencing the "Service Engine Soon" light illuminating even when the engine appears to perform normally. This can indicate various underlying issues that may require attention, ranging from simple problems like a loose gas cap to more serious concerns such as a malfunctioning oxygen sensor or catalytic converter. Many owners find it crucial to identify and address the root cause of the warning light before attempting to reset it, which typically involves pulling the trouble code and ensuring the vehicle is driven until the system recognizes the issue has been resolved. Additionally, specific trouble codes related to the cylinder 4 oil control valve may signal problems with the oil supply solenoid valve or the Variable Valve Actuator (VVA) Solenoid. Some owners also note that an old battery can contribute to dashboard warning lights, emphasizing the importance of replacing the battery every three years to maintain optimal performance. It is advisable for owners to have their Jeep Renegade inspected by a qualified mechanic to prevent potential issues from escalating.
