Car is a 96 turbo 2000. On way home from work CEL came on after about 2 mins and car would not tick over (had to heel and toe). Once warmed up light went out and car drove normally.
Just done ECU read and get code 21, anyone know what this is and/or what to do about it?

21 - engine coolant temperature sensor

Thanks Ramdor, off to check sensor while its still light enough.

Well theres no chance of getting to that easily...
Anyone know if its ok to run with this fault until the weekend?
Do sensors often go down or is it more likely to be a poor connection?
