No I'm the only Z in the area unfortunately. 

Am I right in saying if I've got a higher voltage going to the sensor it could be a short from another wire into the EOT loom or most likely the ECU is the issue? Because my car things it's cold that means the output of the sensor must be a higher voltage something like 4 volts plus?? 

Another theory could be on the return to the ECU another system could be shorting into the EOT wiring?

Any of this sound logical 

I'm leaning towards ECU personally. Going to run a continuity test on the connections see what the crack is 

It was an issue before the sensor change. Been playing and the code will clear now but the second time you start it after clearing it comes back 

Express factors...it's a Bosch sensor 

Cars throwing a P0198 code Engine oil temp sensor (EOT) high voltage. Changed sensor and still got a light and oil temp gauge won't go above 70°c. Also started after an ECU reset. The reset was because I had a Powerflow cat back fitted and it was throwing a miss fire code (car wasn't missfiring). The car hadn't been tuned yet and I was advised on sites and by tuners to reset the ECU. 

Now i have a new sensor the code won't even clear and the light stays lit up.

Car feels sluggish at lower revs also but I've been told the EOT sensor helps the ECU with air fuel mixes so that explains that in my eyes 

I'm really stumped on this so any help would be greatly appreciated.
