Front Oxygen Sensor Replacement Cost
RepairPal Fair Price EstimateLearn more
RepairPrice Estimates are based on the estimated time for the repair, labor rates charged by trained automotive professionals, and prices for quality parts.
These estimates are designed to show a range of fair prices, instead of a single price, because there is more than one part that is appropriate to use in each repair, and more than a single mechanic who is qualified to do the repair.
Each estimate is customized for your vehicle and geographic area. Estimates exclude applicable taxes, diagnostic charges and disposal fees.
A failed oxygen sensor may cause the vehicle to fail an emissions test. The failed sensor will cause a trouble code to be set and the Check Engine Light to illuminate.
Oxygen sensors can fail if they are contaminated with oil, coolant, or silicone. If fluid contamination has caused an oxygen sensor failure, the source of the fluid must be resolved or the new sensor may be ruined.
Intake and exhaust leaks can trigger an oxygen sensor trouble code, but the oxygen sensor does not require repair. Repairing the leak will resolve the problem.
On vehicles 1996 and newer, using an inexpensive "universal" oxygen sensor will cause problems with the emissions system and is highly discouraged.
