Hi all, my car is throwing up another fault...17705 pressure drop between turbo and throttle valve.One the the suggestions is a faulty diverter valve. Is this a simple diy fix ? And can someone be kind enought to tell me exactly where it is..am i right in assuming that its to the right rear of the engine just by the air mass sensor.I have attached a pic.Is it just a case of undoing the clips pulling off the pipes and replacing with a new valve?

Hi, thanks for the input.Have had a mechanic friend quickly look at the sensor plug with a multmeter and he reckons there is no power to the heater circuit at all.Reckons he will now check to see if the sensor heater circuit is connected to any fuse, on the assumption that there may be a fuse blown that is causing the eml to come on as sensor maybe not getting up to working temp? Are you aware of any such fuse that may be causing this?

Hi, Thanks for the input. What exactly do you mean when you say that? What does one need to look out for?

thank you. thank you.However can I test a sensor by measuring it resistance across certain pins?

Hi All, I have a 2003 skoda octavia 1.8T Elegance estate that I bought a while ago. Yesterday the engine management light came on and and after having it code read I have the following codes on it.. 17522 16524 17522 17526 All of which relate to oxygen sensor bank 1 sensor 2. however my question is that from what I can see in the paperwork this sensor was replaced in August 2015,surely it should last longer than this? I have been told that one can check the sensors by measuring the resistance across their pins.Does anybody now what the resistance should be across a good sensor and what pins to attach the multimeter to? I would be very grateful for any feedback. Thank you in advance for your help.
