Exhaust Gas Temperature Too High Bank 2
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
An EGT sensor on bank 2 reports a temperature above the safety threshold for prolonged operation - typical for blocked DPF, restricted exhaust, or excessive fuelling. Risk of catalyst, DPF or turbo damage.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
