Well guys i`m getting a VTEC Oil Pressure Switch code ... and also a 41 code Primary Oxygen Sensor - Heater. Now for the code 41 .. all i know is that i need a 4 wire o2sensor since my new p28 seems it won`t accept any single wire ones.. Anywayy .. any good place i can buy one ????? r they all standard for all honda models ?? However ... the oil pressure thing i have NO Idea still ... Vtec works great you can feel it above 4000revs .. so, what the hell is the ecu reading ? If there is some loose connection .. were exactly should i look? Checked all the connections near the dizzy .. they all seem ok .. Help!
