saxo 1.1 coolant temperature sensor

  1. #1
    Hi,

    I have a saxo year 2001 and I have idle/running prblems. Either the idle is to low and sometimes it goes off or it revvs to 1500 rpm. I disconnected the icv and the car stalling is reduced also the revving to 1500rpm has decreased. But yesterday I disconnected the coolant temp sensor that has a yellow ring and only one wire connected to it, when disconnected this sensot is not making any different to the car ! Does this means that the sensor should be replaced ?

    thanks
    regards
