discuss the problem with a service dealer shop or an accredited service shop that has experience on your make of vehicle
with rocker arm problems , to stop rotation it may be bottoming out on a valve spring and not letting the cam shaft turn .

P2647: Rocker Arm Oil Pressure Switch Circuit High Voltage

What does it mean when the vsa indicator and the engine emblem appears at the same time with code p2647?

I am not sure why they would both come on at the same time but the code P2647 means - Rocker Arm Oil Pressure Switch (VTEC Oil Pressure Switch) Circuit High Voltage.

So first thing first in diagnosing this code is to check the oil level.
Have the engine run for a bit and get warm to build up proper oil pressure. Then turn engine off and let the vehicle sit for a minute or two. Have the vehicle on level ground and check the oil level and condition.
If the level is low then top up till it is at the full line. When the engine oil level is low it may not have enough oil pressure to control and activate the VTEC system thus causing this code.
If the oil is super dark and black then you may be due for an oil change. (should be done around every 5000km.)

Took my 07 honda ELement to fix at a dealer . given them the coda P2647 rocker arm actuator bank 1stuck on . there fix vtec switch& oil was a lot of money and still got the same

you don`t say who gave you the code.if you gave them this code not wanting them to check for coeds then you started this problem by not allowing them to check for a code as they would do a more indepth code check then diagnois the problem this case because they did all the work then they would be more inclined to give you a break and correct the problem compared to someone that gives them a code and doesn`t want anythng else done but the code problem putting the owness on the customers request.this is unfortunatly what happens alot because the customer won`t pay to have a job done correctly thinking they will save more money doing it this way.

Check engine light on on 2005 honda accord coupe. 4cylinder. code is p2647 said trouble shooting do all repairs on vehicles but do not know that code.

p2647 is rocker arm actuator A- bank 1 stuck on--- to fix it should be the VTEC oil pressure switch. That switch will be on the cylinder head. Towards the windshield and passenger's side (I think).

Go to www . hondapartsdeals . com {remove the spaces when typing}

Go to parts, enter your car's info. System: Engine Component Vtec Oil control valve. That diagram should help a lot.

Good Luck.
