ALL codes should be cleared - operate vehicle - when service engine soon / check engine light illuminates again - have codes gathered soonest for most accurate troubleshooting tips.. Recommend *PROFESSIONAL SCAN TEST* when light turns on again. SCAN TEST is much more involved than simply reading codes - - pertinent data can be observed for more detailed evaluations including components functional testing.
