Finally got live data with hq opcom. Although fault is off now. Sure it wont be long till its back on as sensor 1 and 2 readings are around 11°c apart. So checked older corsa with z17dtr and both sensors on it were reading identical

Connecting as an Astra J works then?

Yep just need to get whatever special grease it is and try that before paying £80 for a temp sensor

hi, I had the same error on my mokka, on the same engine a17dts, until this morning. Well, the problem was from january, after just a few weeks after I purchased the car. This morning I decided to have a look at the first sensor and it's not that easy to get to it (see the attached picture). I disconnected the sensor wire and I cleaned with WD40 specialist fast drying contact cleaner. After a few minutes I connected again the wire harness and checked if I get any error and yes the error is gone now. Hope this was helpful

I suppose the sensor can be tested, why you should want to know exhaust temperature seems a bit strange, bit like fuel temperature, i'm sure we could live without either of them, i haven't looked at a circuit diagram but my guess would be you have 2 wires, a 5 volt and a controlled earth via ecu, or a permant earth and a controlled input...it probably works like a water temperature sensor.....Fred.

Hi folks. Lost my login details and password reset is being sent to an email account that is now defunct, so new account now opened with new username.
Anyway, I have the same issue with my Mokka and the connector is a pain to get to. I have removed coolant expansion tank to gain more access, but still no joy. How on earth do you get to the yellow connector?

The instructions on TIS say to access from underneath

Preliminary Procedures
1. Battery Negative Cable Disconnection and Connection
2. { If equipped } Drivetrain and Front Suspension Frame Skid Plate Replacement

3. { If equipped } Front Compartment Front Center Insulator Replacement

Thanks for your helpful reply. I had wondered if that was a possibility. Just replaced my air con condenser, that was a pain, but less of a pain than it would have been if I had followed the Haynes manual instruction to remove full front bumper. Not necessary at all.
