My 2002 subaru Legacy b4 has just started to not change to 5th gear in tiptronic or auto. I have had a knocking noise that happens only when accelerating and have read that it could be knock sensor. My question is.
1. Does the knock sensor issue stop me using 5th gear or is this unrelated?
2. Shouldnt I have a check engine light if the knock sensor has a issue?
