Check Engine Light On, Engine Runs OK on Kia Spectra5

The Check Engine Light may erroneously illuminate, signifying a fault with the front oxygen sensor when no fault exists. Replacing the electrical connections at the oxygen sensor with a repair kit available from Kia will commonly fix this problem.
