Has anyone got any experience of this error code? I have a Pajero io 1.8 GDI turbo and this has started to come up when the engine is run at speed, basically when you’re consistently going about 60 mph + . I was having some issues related to the high pressure pump which was replaced and fixed them, related its also had a new MAF, spark plugs, new exhaust.
As part of getting the new exhaust, and related to the HP pump issues, the cat coming off the exhaust manifold (part MR514544) had been damaged with what I assume was overfuelling / running too rich, so I had to scrape out the interior.
The car is running totally fine, the engine coolant doesn’t seem to be going over temperature - anyone have any ideas what could be causing this?
The car has only one O2 sensor from what I understand which is pre cat - so I don’t see how it can be determining catalyst efficiency? |
