p3214 - 004 - heater return coupling - intermittent
Dear Folks,
While diagnosing my intermittant cylinder misfire on Cylinder 9. I am getting the fault code; p3214 - 004 - heater return coupling - intermittent. Please let me know if this is a fault with that Lambda sensor or the effect of some other fault? Looking forward to any guidance you can offer. Kind regards,

Either sensor itself or Wiring too it would be my guess.

Thanks Del,
I'll have a crawl around. Is there any guide to checking these with a multimeter? Cheers
