Hey guys
i have just put a jdm b18c engine into my 92 delsol. I'm running the p72 ecu. I am throwing a code 41 which is the primary oxygen sensor heater. I'm confused about this though as I am running my old loom and only using a 1 wire oxygen sensor., Does'nt that mean i dont have a heated o2 sensor, so why would the code be going off??????? Also 3 of my header pipes are getting really hot and one only warming slowly, does that mean the cylinder isn't firing?/??

Please help me out

Closest thing I found to our problem...Check it.

the ecu is looking for a heated O2. That would probably be why you're throwing a code. It probably is a bad sensor in addition to being the wrong sensor.
Also, I'm guessing your cam timing is way off, thus making the weird heat issues.

Any specific way to bypass this code??? trickin the ECU into not knowin its fine?
