Oxygen sensor replacement cost
for a Toyota Hilux

Replacing the oxygen sensor(s) on a Toyota Hilux involves locating and removing the faulty sensor, typically screwed into the exhaust manifold or downpipe, and installing a new one. The cost is primarily driven by the number of sensors (most Hilux models have at least two) and the sensor's location, which can make access difficult and increase labour time.

Can you do it yourself?

Possible with skill — Requires basic tools, vehicle jacking, and the ability to disconnect an electrical connector and use an oxygen sensor socket.

Tips before you pay

Use an OBD2 scanner to confirm which specific sensor is faulty before replacement.
Apply anti-seize compound to the threads of the new sensor, but only if it is not pre-applied (some are).
Disconnect the battery before starting to prevent electrical issues and allow the ECU to reset.
