Hi. I have spanner/service light on "permanent" now, as it was on/off whilst driving prev. Plugged my obd2 reader in but no codes there so, done pedal test and a code was there P111606. Looked it up and code relates to -low voltage in thermo circuit. Got under bonnet and looked at thermo sensor (screw in type i replaced last year bulk head side of thermostat) It has a 5v supply and resistance of 2.55. but then noticed there is another sensor (rad side of thermostat. This one looks like a push fit with spring clip and has a supply of 8.25v (higher than other sensor) but lacks any resistance. So my question is have i hit on the naughty part and just need to replace the push fit sensor? Thanks all.
Turning out to be a right pain sourcing out a sensor switch for this thing. Has not anyone in the bizz seen or heard of one? Even vauxhaul said they don"t stock them so asked them if i brought car in for repair where would you go to get one then. No reply, of course. Breakers sending pics of wrong sensor, WHAT"S GOING ON?
May have solved the "sensor mystery! Silly me, i was looking online for a fan sensor for a vaux. (my car) Whilst nothing was coming up i looked for a sensor for another make of car to see what they were using and there it was.
