Hi

 

 

Some day ago my check engine light came up and i got error code P007B 
ODBII: Turbocharger (TC) Intercooler temperature sensor, bank1 - circuit range/performance

Where is that sensor located and how does it looks like? I thougt first it was AIR INTAKE sensor check pictures but its wrong one. 

My car is Octavia MK3 Facelift 1.0 TSi Engine

Thanks!

Or is it this one?

The last one just looks like a pipe connection.

Ye. I  found annother sensor that is mounted on intake  and looks like this

^ The part number for that one comes up as 'boost intake pressure sensor'.

So it would be the sensor 03G 906 051E that have temp built in and not the first picture 04C 906 051

Think it is a combined pressure & temperature sensor in the one package.

Ye i think that too but i dont know the location. I found 2 sensors that is for Air Pressure you can see the one on TOP and one i found on annother location at intake mainfold last picture. Im confused wich one i should replace

 04C 906 051  03G 906 051E is the one you probably need if it's got the temp sensor built in.

I think it will do if you can't find any other sensor in the intake.

03G 906 051 E Sensor, Boost pressure, Air pressure sensor, Height adaptation, Sender unit, Intake air temperature OEM VW, AUDI, SKODA, SEAT, PORSCHE (autodoc.co.uk)

Damn, I said the wrong one didn't I It's  03G 906 051E

YES mate we did. Best SKODA forum ever. Many thanks to all of you

Sensor ordered i will keep in touch if my problem is solved then change topic to solved.

Ok i replaced the sensor this morning and before i replaced sensor every time the car was coldstarted rev goes up and down before car is warmed up then after 1 min it goes down to normal. Now when i start the car with the new sensor the rev counter did not do that anymore it is stable.

It looks like a map sensor which reads absolute pressure.

Ah ok thanks. 

My husband's SE had a similar error message which was a failure of the Turbo actuator. Turns out that giving an Italian tune up solves the issue (he drives for economy, so never much accelator).

 

Turbo actuator was cleaned up with brake fluid and replaced back in. Every week....a good hour of vigorous driving keeps the roarly little 3 pot a happy bunny.
