How to Reset the Service Engine Light on a 2002 Nissan Maxima
The 2002 Nissan Maxima is equipped with an on-board diagnostics two (OBD2) computer system that monitors all of the engine management system functions. This system alerts the driver if a fault exists in one of the system components by turning the Check Engine Light on, located on the instrument cluster, and storing an alpha/numerical code that identifies the faulty component or system. After the fault is repaired, the check engine light must be reset with an automotive scan tool.

A code that returns after several days may indicate an intermittent fault in that system or a part.
