EML - Coolant System
1.8 Civic ES Mk8 (2006)
Bit of back story as to how I've come to the below conclusion, in case anyone has any further advice/ wisdom/ knowledge to impart:
A month or so ago I had the EML come on, booked into a local garage and in their words "it's showing 2 faults, one is the lambda sensor, the other is the coolant system". I didn't ask to see the codes, although I wish I had. As it wasn't clear exactly which code it was, and the car showed no symptoms, code was cleared just to see how it went. Day after next the EML came back on. Given that the coolant level was fine, engine wasn't overheating, and the fan was working, I assumed it was the lambda. Left it a few days and the EML went off of its own accord.
Fast forward to last week, EML comes back on, my assumption is that it will be one of the same codes again. This time however the fan is running a lot, even from cold on some days. Again, look in radiator cap, coolant full. Ergo, probably the temp. sensor. EML has now gone off again, however the fan seems to still be running a lot.
Am I on the right track, or could it be a relay (something I've read)?
Thanks for any and all input.
