Default JCW intermittent P0054 Engine light comes on - 8th May 2018, 10:03 AM

Hi,

Recently brought a JCW convertible. It does have a slight error which comes up as P0054....(ho2s heater resistance)

Looking through the paper work it had the whole exhaust replaced and oxygen sensor changed 2 years ago.

As the car does have a slight lag or mistiming when accelerating....as in there's a dip before picking up. seeming like the oxygen rate isn't correct.
I have ordered a replacement sensor and will be in the process of getting some plugs too.

But any info welcome.

Thanks

There were issues with the High Pressure Fuel Pump (HPFP)’on the models but hopefully a new sensor will resolve the problem. After the replacement I would recommend a full service and higher premium fuel.

Thanks,

First tank I filled was 95,
Now just stuck some premium in(definitely pops more now on the wind down)!! I have ordered a new O2 sensor and wanted to look at a service and plugs.
