Within the past three weeks, I have paid $1500 to get an Oxygen sensor replace, EGR valve, EGR modulator, and VSV replaced on my 1997 RAV4 for a check engine light problem. However, after getting all of these repairs, the engine light is still coming on. Code PO401.
Why is the check engine light on? on 1997 Toyota RAV4
