Frequently asked questions

What is the ERR6729 oxygen sensor?

The ERR6729 is the oxygen (lambda) sensor for the Rover V8 EFI petrol engine with catalytic converter. It measures oxygen in the exhaust so the ECU can adjust the fuel mixture. It fits catalyst-equipped V8s in the Discovery 1 and Range Rover Classic.

How do I confirm the ERR6729 fits my vehicle?

The ERR6729 fits the Discovery 1 (1989-1998) V8 EFI with catalyst from VIN FA393361 to WA799999, and the Range Rover Classic (1986-1994) V8 EFI with catalyst from VIN FA351847. Use your VIN to confirm the catalyst spec before ordering.

What are the signs an oxygen sensor needs replacing?

An oxygen sensor typically fails with age or contamination, causing poor fuel economy, rough idle, failed emissions or an engine light. A lazy or dead sensor makes the V8 run rich. Replace it if fuelling faults point to the lambda circuit.

Where does the oxygen sensor fit?

The oxygen sensor screws into the exhaust downpipe or manifold ahead of the catalyst. Fitting typically needs an oxygen sensor socket and often some heat to free a seized thread. Anti-seize on the threads helps future removal.
