O2 sensor on a d4f

[GRitch]

Could an o2 sensor make a misfire on a single cylinder on a d4f engine? Have the eml on this morning with 2 faults. Any help would be appreciated

Unlikely on just one specific cylinder.

 

[GRitch]

Any idea what else could have caused it?

 

[MicKPM]

Plug, ignition lead, injector, engine condition on that cylinder. How do you know it's missing on one specific cylinder?

 

[Alastair.]

Coil pack or injector likely, saying that the last 2 I have looked at have had a burnt out valve.

I had a universal code reader on it and it came up with codes p0316 and p0314

Not gonna be o2 sensor, check the easy stuff first - is there a wire loose? plug ok? then compression test to rule out internal damage. then coil pack, injector...

 

[Dan519]

check the loom condition too

This to... its a 1.2 16v afterall

 

[GRitch]

So I checked the rest of the stuff out and still have a slight miss on a single cylinder. I have also got an o2 fault on the second o2 sensor. Where are both the o2 sensors located? Would be much help

 

[GRitch]

Also could it be possibly be due to water? Lots of rain and puddles been a factor? Maybe letting it dry out?

 

[GRitch]

Any more input on this?
