Had a few recent problems with my focus 1.8 petrol (08 plate) 20k
1) Noticed fuel consumption was up and guzzling quite a bit more than normal.
2) Entered into the Diagnostics mode on the dash screen display and scrolled through the menu until I found the engine temperature! - This was showing 136 c in some instances dependant on if I was moving or stationary idling in traffic.
3) The dashboard gauge however always stayed in the centre (normal) position.
I wanted to put my mind at rest but initial thoughts were the first 2 points above might be linked to a faulty sensor of something?
Anyways I therefore took it to Ford today just to check out. They told me that the Engine Temp (i.e. 136 c) was the recorded temperature of the Cylinder Head and this was normal and nothing to be concerned about.
The issue with my fuel consumption was the PCM had the wrong tyre size inputted into the system – I have driven it 30 miles today since they corrected this and it seems to have made a difference already.
Just wondered if anybody else had similar concerns with Engine temperature reading – Don’t be alarmed if you have cause apparently this is quite normal. But anyone with increased fuel consumption who drives economically like myself it may be worth a check into Ford .
hopefully all sorted now
