EGR Valve VS temperature sensors

Hi,


Need a little help here please.


At the moment I have a diagnostic code P1405, meaning “EGR tempereature sensor incorrect” as far I know through the internet.

This is the actions done so far:
I recently cleaned the EGR due to P1405 (EGR temperature sensor incorrect) diagnostic code using HiCOM diagnostics. After the EGR cleaning decreased the fuel consumption but the consumption is still too high and I still get the diagnostic code P1405 after driving a while... I called my local Hyundai dealer to ask for a price of this EGR temp. sensor but they said there was none... Hmmm, how come i get EGR temp. sensor incorrect...

Then did I check the following:
The temperature over the different sensors:
Oxygen Sensor at cold engine: 475.690 celcius:eek:
Oxygen Sensor at hot engine: 682.921 celcius:mad:
Exhaust gas temp pre CPF at cold engine: 127.259 celcius:eek:
Exhaust gas temp pre CPF at hot engine: 131.968celcius:mad:
Exhaust gas temp pre VGT at cold engine: 127.259 celcius:eek:
Exhaust gas temp pre VGT at hot engine: 164.937celcius:mad:

The conclusion is that there is an issue with the oxygen, pre VGT & pre CPF temp. sensors. I have located the oxygen sensor but not the pre VGT & pre CPF temp sensors.
Is it the diagnostic tool that is tricking me as I’m using HiCOM on a 2.2CRDI (155HP)?
If not can someone please help me out locating the pre VGT & pre CPF temp sensors?

All answers are appreciated, thanks.
