Hi, I have a 2005 acura tl base W / Navi, and I have a problem! My acura does not go higher than 5500 rpm, so it cut off at 5500 and when I have it at 5500 it recognizes a code after 4 seconds ... the code is P2646 ... I am a teacher and have my propose to change my oil pressure switch vtec. I change it and it does not change anything!
ps: it detects the code P2646 only when I hold the 5500 rpm after about 4 seconds otherwise it does not detect thank you !!

Are you revving in neutral? It wont go above that.
OP, you cant go above 5000 RPM in N
my engine has full oil, but the transmition remains more oil, really little! its the one report or really no way
