well i am getting the low oil pressure code after changing oil to castro syntec 5w30,
BUT
the defi is telling me 2.0 at idle and 5.0 at full throttle which is normal

what is wrong with my car ?

 

unplug the battery to reset the computer and then see if the code still comes up. could just be a sensor that had low pressure for a second and didnt reset itself.

 

There is no generic "low oil pressure" code.. There's a light, which is connected directly to a sensor, which turns on if you have no oil pressure at all. You're probably seeing a code about low oil pressure to the vtec system. As stated before, try resetting the ecu. Where's your oil feed for your turbo tapped from?

 

good point Mr. exploting potato !!
the oil feed tees off front th oil pressure sensor from the front of the block, where the oil pressure for defi is from the sandwich block for my oil cooler.
so may be it's ****ed up from the oil feed...
i'll check tomorrow
thanks for the advice

 

What code exactly is your scangauge pulling? Should be something like Pxxxx
