I need to repair both oxygen sensors (check engine light on) code PO 171, 174 - What is the cost for this repair?
Buy the sensors and put them on yourself. Buy the aftermarket. They are the same. OEM will cost you about $110 each, Aftermarket $65 each. I work for Bosch and run the line that makes oxygen sensors, there's a lot people don't know about aftermarket and OEM. These can be removed with a 22mm wrench or you buy a special oxygen sensor removal socket/wrench. It's a matter of getting it loose. Run the engine for 1-2 min to warm the exhaust, this helps to loosen the sensors and keeps from stripping the threads. If a shop does this $250-325 depending on shop rates.
