P0217 Code

[Lez]

Hello I'm new to this site and was wondering if anyone can help me?
I drive a 2004 Terrano which has the EML on and when I plug my OBD reader in comes up with the code P0217 and says Engine Coolant Over Temperature Condition. I've changed both the temperature sensors and the antii-freeze.
Does anyone have any other ideas what it could be?:nenau

Have you checked the thermostat? Also where does your temp needle sit at when engine is up to temp?

Also check your connections on your sensors.I had the same problem.

Yer I've changed the thermoset, and the temperature needle sit in the middle of the gauge as normal?:nenau

Mine sits just above 1/3rd.

Yeah that sounds good to me I've got a 2004 and my needle sits in the same place, the problem is that you don't know when that code was stored, clear the stored codes, drive it round again and re-check

It may have just been an anomaly, or you may have fixed the issue with the components you've replaced

clear the codes and see if it returns :thumb2

I don't have much faith in my temperature gauge. In a straight line, it sits below half way. On windy roads, it moves from sub zero to half way as if it is a brain damaged weeble. Once I'm in a straight line, it sorts itself out.

If I see steam/smoke/flames, I'll stop and investigate.

Confirmed this is normal :thumb2

+1 both of mine have been like this unless they have got warm from working hard off road then the temp gauge moves to the 1/2 way point or just past it (but no where near 2/3rd's) & the viscus fan kicks in

which engine, if you put it in your signature or avater, saves us asking again

As you are aware there are two temperature sensors fitted, one is for the instrument meter and the other is for the ECU.
The two sensors are in no way interconnected, other than by the coolant. The only way an over temperature DTC can be logged is from the ECU thermistor/sensor, the gauge can do whatever it likes, it will have no bearing on the DTC logged.
As these sensors are NTC thermistors the resistance will decrease with rising temperature, so a bad connection is not probable, however a short to ground on the thermistor wiring for the ECU could be consistent with with your problem.

Thank you All, Have cleared the codes switched the EML off, but it returns with the same code.:doh

I would have a careful look at the wiring from the sensors to see if you have a broken wire or one that has rubbed through it's casing
