VTEC Spool Solenoid Valve,

I have great oil pressure, no oil leaks, everything is wired up correctly yet still I am throwing a code 21. VTEC spool solenoid. Any ideas. I have checked the o-rings around the solenoid itself. I am at a loss.

 

Is it hitting VTEC? And what ECU is it?

 

Nope not hitting VTEC. It is a P28.

 

Has it been Chipped or is it Stock? The ECU.

 

It is socketed. But the wierd thing is initially all I had was a code 7 (TPS) and 14 (IACV) Fixed both of those and suddenly I have code 21. ???

 

If there is no short it sounds like it could be a bad burn.

 

I am leaning towards something mechanical almost now.

 

swap out the vtec sol with one of ur buddys, see if it works?

 

how's your grounds?

 

the jumper is cut right?

 

Ok, it was a loose pin on the plug into the ECU. Fixed.

Thanks guys for the ideas.

Funny... I was gonna suggest you take a look at the wiring.
The same thing happened to me when I first put on the VTEC head and P28.
