I have a 2014 fiat 250 ducato based moho.
It is throwing up the above fault code that then sets check engine light on dash.
It is very disconcerting to drive whilst this is on although probably a minor fault. It is very intermittent and can throw the code after driving many miles.
I have replaced the fan sped resistor as it cheap and easy to do but to no avail.
I have looked at the heater wiring diagrams and although there are a few relays
in various locations that control the heating none are called "blow-by heater relay control?
Is the fault code irrelevant and I am going down a wormhole of replacing relays until i find the culprit.
Sorry I forgot to say that when it throws the code the heater goes off until I restart the engine when heating resumes but dashboard error code stays on until I use MES to reset the errors.
Can anyone help or seen this before?
Cheers happy new year to all.
