Hi everyone I have 04 Honda Accord LX. So I got a code p2646 I believe it is and was told it's a vvt variable valve timing pressure switch. Now I have a check engine light on but I definitely need a oil change. Do you think I should try to change this part first or try an oil change first to see if the check engine light goes off? And is there a difference between the variable valve timing pressure switch and the solenoid?
If it's due for an oil change you need to do that in any event.
You can find some troubleshooting tips for that code here:

Thank you I'll change my oil tomorrow and hopefully all this goes away.
So let's say I change my oil and the engine light goes off and I still want it to change the variable valve timing switch, would that be pointless in a waste of money to change that piece still or would that be beneficial in any way?
Probably would be pointless if the error code clears up.
Ok thank youm appreciate it
