Oxygen sensor replacement cost
for a Ford Explorer

Replacing an oxygen sensor on a Ford Explorer involves locating and removing the faulty sensor, typically on the exhaust manifold or downstream of the catalytic converter, and installing a new one. The cost is primarily driven by the sensor's location, which affects labour time, and the specific model year, which determines the sensor type and price.

Cost breakdown

Parts: ~$60-$120 / Labour: ~$120-$230

What affects the price

Sensor location (upstream vs. downstream; accessibility varies greatly)
Model year and engine (affects sensor type, price, and connector compatibility)
Shop type (dealership vs. independent mechanic labour rates)

Can you do it yourself?

Possible with skill — requires a proper O2 sensor socket, penetrating oil, and basic mechanical knowledge to safely access the exhaust components.

Tips before you pay

Use an OBD-II scanner to confirm which specific sensor (Bank 1, Sensor 2, etc.) is faulty before starting.
Apply penetrating oil to the sensor threads well in advance, as they are often severely rusted in place.
Ensure the engine is completely cool before attempting the repair to avoid burns and damage to surrounding components.
