Coolant Temp Sensors Differentiation - 2004 Citroen C3 1.4i

Unread post by breadcast »

Hello. I have fault code P0115 - engine coolant temp sensor 1 circuit. My Citroen C3 has two coolant temperature sensors, an upper green sensor with two wires and a lower blue sensor with 1 wire. Does anyone know which sensor the fault code refers to? Thank you.

The green one is for the engine management system.

Does the P0115 code apply to the green, rather than the blue, sensor? Thanks.

Yes, the green one, they are a fairly common failing part.
