So yesturday i get a check engine light on my 03 s60. I bring it to autozone to get the codes.
1-p0133 which i was told was the o2 senser in bank 1 sensor1
2- p2407 which was some sort of pump sensor
The o2 sensor looks fairly easy to replace. has anybody change one?
As for the pump sensor any idea to what pump it is?
