Oxygen sensor replacement cost
for a Toyota Camry

Replacing a faulty oxygen (O2) sensor on a Toyota Camry involves locating and unplugging the electrical connector, then unscrewing the old sensor from the exhaust manifold or pipe and installing a new one. The cost is primarily driven by the number of sensors replaced and whether the sensor is an upstream (pre-catalytic converter) or downstream (post-cat) unit, as upstream sensors are often more expensive. The specific model year and engine size also affect parts pricing and labour accessibility.

Can you do it yourself?

Possible with skill — Requires a special oxygen sensor socket, basic tools, and the ability to safely access the exhaust system.

Tips before you pay

Use an OBD2 scanner to confirm which specific sensor (Bank 1 or 2, Sensor 1 or 2) has failed before purchasing parts.
Apply a penetrating oil like PB Blaster to the sensor threads well before attempting removal to prevent breakage.
Ensure the engine is completely cool before starting work to avoid burns and ensure proper thread engagement for the new sensor.
