Hey everyone im new to the civics but I just got rid of my B16 DB1...Im having some issues with this hatch that i just picked up. Its got the stock d15b7 in it but by the ecu where the check engine plug is its a blue plug like in the article on here stating its a ek (obd2) the odd part is its the stock P06 ecu but the plug is blue not grey..... It works like it should and is telling me that I am popping a code 41 which is the oxygen sensor heater if the article on here is correct.

If im not mistaken there should not be a heated 02 sensor on this car since it is mainly stock. Could anyone help me out? The car drives fine but sometimes the idle surges which im figuring it to be the IAC valve needing cleaned out am I right on that?

Any help is greatly appreciated

heater is built right into the O2 sensor. just look at the O2 sensor there should be 4 wires on it.
