My CEL light came on the other night. Code #22.
================================
94+ Integra VTEC Oil Pressure Switch defective circuit or unplugged / defective oil pressure switch
* invalid code for non-VTEC engine
================================

The car runs perfectly. Oil level is full.

Is there any way I can fix this myself without taking it to the dealer? Last time, the tech had himself a nicey-nice 10 mile test drive

 

install anything lately?

 

Bone stock.

It was about 20 degrees outside when it first came on, if that makes any difference?..

 

I had an intermitten CEL #22 for over a year and finally figured out what it was 3 weeks ago.

Two things I'd check:

1: Screen on the VTEC Solenoid. Sometimes metal shavings from deteriorated rod bearings can end up in there and clog the screen causing the CEL

2. The Spool Valve may be sticking and needs cleared (this was what happened with mine).

Item #10 from the attached URL is the VTEC Solenoid (https://honda-tech.com/zerothread?id=340008) Unbolt the three bolts on the top and remove the top half of the part. There will be a "button", that's the spool valve. Make sure it's not sticking, but pushing it down a series of times.

That's all I've done to mine and it cured the CEL problem. I did several of the tests in the Bentley, took the car to the dealer 2x and never could determine what the problem was. I guess there was some debris in the valve not allowing it to move and by pushing it in several times I free'd it up again.

I went from a CEL #22 every day to none for three weeks now by simply doing that. I hope it cures your problem too!

 

how many miles? reset the ecm and see if the code is stored. if not dont worry about it. if it does there is a whole flowchart to follow on troubleshooting. check all of the vtec related wires also.

 

thanks guys.

ecm reset fixed it.
