ok I've done some research on here, but nothing seems like a definate answer, so I'm bringing this thread back from the dead...

B16A
PR3 ECU
OBD0

I'm throwing code 22 (vtec oil pressure switch), I've replaced the sonova bitch 2 times already, wiring looks good, oil is good, and also my rev limit has changed to about 75-7600, rather than 8200..

Ideas on how to bypass?

 

does vtec engage? most likely no. have u ever replace the oil pan? or bottomed out. clean the vtec sil filter.

 

sorry, forgot to mention that ive cleaned the vtec solenoid also... yes vtec does engage sometimes, but 99% of the time, it will throw a CEL in 3rd gear after vtec engages

 

have u ever bottomed out. ur car like bent the oil pan or replace the gasket. have ur change ur oil resently. when u do is it dark or still goldish. are u low?

 

Did you check all the wiring, and with a tester. You can't just eye ball wiring.

I would rerun the wires.

 

i mean really theres nothing to rewire, no wires look fried or anything, the ground is good, no corrosion or anything...
no i am not low on oil, i just had my oil changed about 2 weeks ago, no i didnt bottom out, the oil pan is not dented

good, but how did the oil look, was it black or pretty good. when did u change the switch. does the oil light in the cluster come on. the only reason i asked about the pan is because if there s a dent in just the right spot. the oil pick can get to much oil or not enough. could be the oil pump, but high unlikely. hard to say are u having any other problems with any thing.

i would buy an oil pressure gauge just to be safe. it could be lower than normal.

 

Upon further inspection of the wiring, the blue/black wire from the oil pressure switch right before it gets to the ECU, it was pinched, so cut/rewire, not throwing any code anymore and i got my rev limit back, and no CEL
thanks for the concerns
