I have a 2007 Acura RDX, and I’ve been getting those three lights popping up on my dash and I have searched up the problem here and some possible solutions like removing and tightening the gas cap. So far I have changed the alternator and I’m still having this problem, ANY HELP ???

 

This can be caused by numerous issues, but it's always been a loose gas cap for me. I know the knock sensor going bad can cause it as well. Do you have a code reader?

REPLY: Yeah I’ve been doing that constantly to the gas cap and I check the reader and got the code P2647

Needs an oil pressure switch.

 

I HAVE CHANGED THE VTEC OIL PRESSURE SWITCH, and it still seems to be acting up, even though I did needed to change my oil pressure switch, the code came back up again, any other solutions???

 

Could be many things. Would require more in depth diag. checking wires, checking voltages, checking ground, checking for a soft set connection either at the VTEC oil pressure switch or PCM, etc. Can't say this is something that will be diagnosed over the internet...

Also looking in the data list on a scanner may tell you some things if you know how to use one comparing inputs and outputs to see what is staying on or being commanded on when it shouldn't be. Could be a faulty PCM as well. On a side note, I doubt it's an oil level issue as that's usually the opposite code (stuck off).

All else fails, bring it to the dealership lol.
