As of tonight the cooling (radiator) fan on Elaine's Na starts as soon as you start the engine up no matter what the engine temp. I've: Checked the relay (not stuck) Reset the ECU (just in case) Checked the connections on the Coolant Temp Sensor (Nice & clean) Which I think really only leaves the Coolant Temp Sensor itself (?). Anybody got any thoughts on this? Cheers Reg

This hapened to me and got me worried as the fan and EML came on when the engine was cold. I bought an obd2 user interface of fleabay and downloaded carsoft from t'internet. It told me there was a fault with the MAF meter on the intake pipe, it turned out the wire was bare so i fixed it up cleaned it and clipped it back in. Since resetting the EML its been fine (rushes off to touch some wood) Not sure if this helps or not. Regards, Craig

Cheers for the reply.
The EML isn't lit though.................

Bit of an update, EML lit this morning, so I reset the ECU (again). Light not on now, but fan still runs all of the time.

Disconnect the coolant sensor wire. If fan stops, then sensor is cause.

i have now the same problem. Do you have any update for that matter??

If sc then: Loom of doom Map sensor Intake temp sensor

just the n/a

[The Batman]

Loom of doom probably Get a code reader and see if you have a code Could also be second lambda

thanks. The weird thing is that it did it some time ago, then it stopped doing it and then today did it again...

Mine does this from time to time and I just reset the fault code and all is well for months and months, you have a fault code latched up that puts the fans on but not the light, that's how it works for some reason. It is the air sensor. Think mine had done it three times in the last few years. Noisy them fans aren't they

Mine did this too. Changed sensor and no issues since. Congrats on the 8 year thread resurrection

Second lambda caused this on mine Or a exhaust with a hole In it

This.  Second lambda returning a lean reading will cause a P1171 code which doesn't light the eml but does trip the fan to run constantly.

What chill said. Same happened to me.

did a search before posting and found this old thread so i said now there must be more experience

 

So i have to reset the fault and replace the second lambda

[FLD]

Check the code first and check for exhaust leaks before you shell out on a new lambda.

[TheRealVXed]

Happened on mine.  I had forgotten to re-connect the Intake temp sensor (grey thing on the intake pipe).  Just a normal N/A too

can also be the Eeeeeee geee arrrrrr valve too.

or unicorn poo in your intake temps
