Yeah exactly. If you want you can chart your oxygen sensor voltages using the torque app, but it would likely have give you a code if they did not work.

 

Started throwing this code today and had a SES light in my 04 disco 2.

The attached photo is how the hoses were closed off since taking ownership of this car back in May 2022. Not once have I had this code thrown…curious as to what’s happening now. I also took pics of all other ports and they appear to be fine without a vacuum leak of any kind.

 

did you ever resolve your P1415 code? I have an 03 disco II and am also getting this code. my vacuum hoses look in good shape. elbow ends are on solid on the SAI valve and SAI solenoid valve. curious as whether you got it resolved and what you did to do so.
