How do you reset the Service Engine Soon Light on a 2001 Infiniti I30?

Answer 1

Infinit's website says that removing battery cables for 24 hours will reset the Service Engine Soon light. Computer memory is only 24 hours so it should go off when cables are re-attached. If light comes back on, take to a service center for diagnostics. Try this next procedure. This worked for me (procedure turned off the SES Light off). Changed the spark plugs using Bosch Platinum +4 spark plugs (four electrodes); awesome plugs. Cleaned the Mass Flow Sensor using Mass Flow Sensor cleaner. Whallah, the light turned off instantly and has stayed off. Performance on car has increased and it runs very smooth. This worked very well for me. The process has tuned my engine and has allowed the gas to burn more effectively. The O2 sensors have responded by telling the engine computer that the engine is running cleaner. Before trying this tuneup process, 89 and 92 octane did turn off the light for awhile as well. But the tune-up turned off the light completely.
