01 1.8 Intermittent Emissions Warning - Deryck Tintagel
The old Vectra has been given intermittent emissions warning via the lamp on the dash. It will come on and go off after a few ignition cycles. The garage I use put the car on diagnostics and told me that it was the engine temperature sensor that had caused the fault light, but as it was the first time it had illuminated and had gone off I was told to keep an eye on it.

It has been on and off a couple of time since so it could be a faulty sensor or connection. The question is the sensor resistive and is there a normal resistance range for the cold sensor? I just thought that I would check both the sensor and connections to see if I can sort it myself before going to the garage.

Thanks

Some resistance data on Vauxhall CTS here:-

Not sure how applicable it is to the Z18XE (?) in your Vectra mind you.

yes it is fitted to this engine, there is a resitance range but you would be very good to spot a fault they run in two stages ie they reach a stage then switch back down to a higher resitance then start again what makes you think that its a cts fault, normal fault/sympton with this is stalling and hard to restart far better to get the codes out of the ecu, paper clip methord or a dedicated code reader.
