Temperature Fault, Fan Running At Full Tilt.

[frajo287]

Hello folks.

My wife has a C3 1.6L Exclusive Auto (2011). Today only a couple of minutes after starting she was presented with a STOP engine over temp message and the fan running on for a few minutes after stopping.

 

I've had a quick look and its obviously not over temp. Anyone had this? Anyone know where I can find a guide on where the temp sensors are located.

 

Cheers

This is a common fault and Citroen are aware of this and there is a fix but it can only be carried out by a Citroen dealership.

 

I'm assume this is a petrol 1.6?

 

If so, this involves placing a new coolant temp sensor through one of the coolant bleed screws which, through some unplugging and plugging in, it bypasses the faulty coolant temp sensor.

 

This fault would be confirmed with a diagnostic check and observing the fault codes logged.

On different cars, a few of us had false high temperature warnings - some as one offs but others frequent and for these, replacing the faulty coolant temp sensors was the fix. As done, you should first always assume the warning is correct and then do checks to show it is false, just in case there is a mechanical problem.

 

On the 1.6 petrol 125 bhp vti AL4 auto gearbox, up to RPO 12291, the temp sensor (1338F3) is at the gearbox end of the cylinder head on the top of a hose box (outlet tank). It is held by a U-clip and has an O-ring seal.
