Variable Valve Timing Control (VTC) System Malfunction

[BadBadtz]

I hope someone can help....

I've just read the following error code from my check-engine light:

56 P0010 Variable Valve Timing Control (VTC) Oil Control Solenoid Valve Malfunction

56 P0011 Variable Valve Timing Control (VTC) System Malfunction

I'm not too sure what it actually means but it doesnt sound good :xcry:

I know from the other post you said you checked the oil.

The k20 oil level needs to be kept at the max all the time or non vtec moments can occur, also what oil are you using?

 

[BadBadtz]

it was full in the morning and when I just checked now its half way on the dip stick?? :?

I'm using Silkolene Pro S 5W-40

I would suggest theres not enough oil to make the vtec operate, try filling to the top mark ( personally i overfill by a couple of mm as do several britcar racers i know), The oil level in these cars is critical as they can use a bit while being driven hard, and can have nasty results if a bit low, my car spun a rod bearing just after i'd got it as i was hammering it with the oil level just above the minimum :evil: :evil:

Top it up and reset the ecu see what happens.
Warm car thru before checking the oil level .
Your oil type should be fine.
Let us know the outcome :wink:

Good advice, I'd certainly be filling it to the brim and resetting the ECU before panicking.

thats the fella!

Thanks C&S Evo7...I'll give that a go but I'm sure something is on its way out :?

Hi

Just a thumb in the air, I have had a few B16A cars in the past, those sometimes suffered from a blocked VTEC Solnoid. There is a metal gauze which can sometimes get gunked up, maybe, just maybe, this is partially / fully blocked and causing unreliable VTEC Control.

With OBD0 / OBD1, the ECU would not necessarily know that VTEC was not firing, as all it does is fire a 12volt feed to the VTEC Solnoid. With our DC5's, I would assume the engine management would know exactly what is happening with the cam phasing.

Sounds possible mate...where do I find this gauze?

 

[martin200]

On the K20? No idea. I will go have a look at my motor now as it is lunchtime, will be back at 1pm, shall advise then.

There are two filters locations -

Firstly, a VTEC Strainer & Filter located on the far left of the cylinder head - facing you as you look at the engine bay.

Secondly, the VTEC solenoid valve and filter are on the same (left hand) side of the cylinder head but this time at the back of the head.

Greatly appreciated mate

Ok, I'll have a poke around tonight...are they easy to remove?

Should be a doddle 8)

Think someone should take pictures of these and write a tutorial, this will become a more common problem as our cars get a bit stodgy

 

[Chuck Rusty]

Seconded

 

[ejwillistyles]

sorry to hear about this mate, hope you get it sorted,
was just wondering from what you said

it was full in the morning and when I just checked now its half way on the dip stick?? :?

I'm using Silkolene Pro S 5W-40

did you first check the oil when the car had been standing & cold then later having been driven & warm? the cyl head will hold a fair bit once run??

good luck with the fix

Have you guys not got the RSX workshop manual?

You can download it in .pdf format. I'd email it to you but it's 40mb. :/

 

[mikegsi]

you can find it on here

Hi

No, I don't have the RSX manual, I thank you for showing me the light

Now, *rubs hands together* time to remove that gearbox
