Faults Cel light on fault code P2185 Engine Coolant temp sensor 2 circut high

waqar · 31st July 2012, 19:11

Hello fellow civinfo guys an gals, im gettin the cel light on i did reset it and the light comes back on the fault code is: P2185 Engine Coolant temp sensor 2 circut high.

I installed the kn 57i induction kit on it 1-2 months ago, but the code came on after a week or two could this code be related too the induction kit? Did i install it wrong?

Did anyone of you get this problem after fitting the induction kit?

I did search the forum as i alway do before i posted this, and got this wiki thread up that after 3 years the sensor and maybe the loom had to be changed. Seriously after only 3 years? I know my car is older then i have been lucky that it didnt occour until now according too the quality of the sensor.
Soo whats next too come?

Link:MIL light for Coolant Sensor 2 - Civinfo Wiki

The car is running normal no symptoms exept the mil light, and yeah the car was low on coolant and i filled it up, and reset the mil but still get the mil check engine light up after several resets of the MIL.

Can anybody guide me thru this nightmare im having? it will be much appreciated. Thanks in advance and have a nice day.

And btw sorry for the poor English it is not my native language, if you dont understand something then let me know and ill explain as much as i can.

And this is on a 2006 1.8 5 door.

Hi I am not sure what help you need. You have all the info you need.

My sensor needed changing on my 06 car lucky it was only the sensor and not the loom.

Ohh my bad, i just wanted too check out if this could be related too the install of the induction kit?

And if people would like too share the experience they had with this fault like you had and, if they had too change the whole loom or just the sensor?

Thank you for sharing your expirence.

What did it cost you may i add?

And do anybody have the part number for the sensor and the loom?

Just check the plug for corrosion and if ok, replace the sensor. One way to stop corrosion in places like this is to spray ACF 50 on all connectors and give the engine bay a good spray with WD40 every year, preferably before winter.

Obviously if the plug is corroded, see if you can get hold of one second hand chop the old one off and solder the new one to the loom

NO do not do this. You would then need a whole loom. Soldering will cause resistance which would cause your light to stay on and a constant fault code.

Cost was about £150 fitted for sensor

I disagree... a properly soldered joint (done by an experienced person) would have very little resistance! Why do you think it would?

Load of rubbish a soldered joint will be fine

Anybody else have some experince 2 share here?

A solder joint that is done correctly should have virtually 0Ω of resistance as you only use enough solder to join to things together.

a 10cm strip of solder will have some resistance yes, but less than 5mm or so will have pretty much 0Ω

The check engine light dont show up anymore, but the engine temp cauge shows a higher temp. Reading about 75 prosent up from max when on idle. Could this be releated too this problem?
