Your problem may or may not be the oxygen sensor. The “check engine” light will “light” when there is a malfunction in the engine management system. The fault code is then stored in the computer. The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component. Because the check engine light indicates something is wrong, a trip to you neighborhood automobile service center sooner rather than later is recommended. Parts and labor to replace an oxygen sensor is approximately $75.00.
