I bought the $8 VTEC Oil Pressure switch that I needed to solve code #22 and now I just cant find the location on the engine to replace it.Im not overly familiar with VTEC 1.8's so please bear with me... The new switch as an end that a hose runs over but ironically it has no hole, it just holds a hose. Like I said.... this switch is very foreign to me and im probably just overlooking something redundant... any help is very much appreciated, thanks guys :-)

 

A pressure switch should cost around $50. :eh:
Anyways, the switch is part number 15 on the attached diagram. It should be located on the solenoid assembly. Hope that helps!

 

I can tell you're the kinda guy that likes to work on his own cars.

Get the service manual...same one as the dealer uses. Don't bother with Haynes or Chiltons, they are crap.

 

Ok so I got up under it today and there is nothing like part #15 connected to anything... I removed what part #13 sits on top of and still nothing like what I have. Also, there is a green electronic connection right thats right next to it that has nothing to plug up to... whats up with that? And could the VTEC OP switch be giving me a faulty crank sensor code as well? Im so lost... I think this guy royally screwed this car up. I mean, I just dont see where this freaking green connector should go onto... *SIGH* I just want to experience the power of a C3 GSR since I have never driven one and as it is I can barely outrun freaking EX Civics and the 6500 rev limiter is killing me. *SIGH*

Please help me... Im so frustrated.... :-(

 

The VTEC pressure switch is on the VTEC solenoid. There will be a 2 wire plug attached to it with a black/blue wire and a brown/black wire. Should screw in and out of the solenoid. As for the crank sensor, those sensors are in the distributor...so it shouldn't be a result of the pressure switch problem. What is the crank sensor code its throwing...crank position sensor?

 

Im getting 22 and 54 as it is now. Theres nothing to screw in or out of the VTEC solenoid that I can see. I'll post pics here in just a minute. Do u have AIM?

 

Here's a pic from the helms:

 

See? No pressure switch.... and an unused connector

 

Code 22 is Vtec System malfunction.
54 is CKF sensor.

 

Look for a solenoid like the pic I posted above that is directly next to the exhaust cam and valve cover.

22 is vtec pressure switch defective circuit or unplugged.

54 is crankshaft speed fluctuation sensor defective circuit or unplugged. I don't have any info on that because its on OBD2 cars, and I have an OBD1 manual. But it's near the oil pump.
