02 with P1259 vtec solenoid?

[slazenger]

I just began having the limp mode issue. changed the oil with no help. I figure i'll just replace the part. I have searched and read the forums but am not clear on which component is bad. is it the VTC oil control valve assembly (part # 7 on OEM diagram) or the VTEC spool valve assemby (part # 4) ? It sound like some people report resolution with cleaning the oil control valve screen. Any clarification and additional info is greatly appreciated.

Could you link us to the diagram you're talking about ?

Just clean it first. Pull bolt number 9, part number 7. Don't lose the o-ring, part number 8 if it sticks to the block.

Thanks my hawaiian friend. I actually run a can of GUNK engine cleaner as directed and changed the oil with 5w20. Still intermittently stuttered for a few days. Finally reset the mainetenance light. It has since run fine. If it acts up again I will clean like you said. Again thanks man. Any additional info will also help.

Don't do that!
Honda has published several articles over the years about the use of cleaners, solvents and additives in the oil. Your Honda isn't a 1950's GM or Ford V8. It has multiple, small oil passages that rely upon simply having clean engine oil.

Take the vtec solenoid out instead and clean it.

I realize after the fact it probably wasn't the best idea. The thing run great since and just recently began doing the same thing with same code. I will clean it later as you guys said. if I decide to replace the unit which unit should be replaced?

I pulled the VTEC oil control valve (part #7) and it looked clean. The screen had no signs of blockage or sludge. I used carb cleaner spray to spray it and the lower parts clean holding it down so no cleaner would get up into the electric part. Now I'll take it out for a spin.

So far so good. No problems over the past 200 miles.

Where does the spool valve (part #4) come into play in this situation?
