i'm getting an oxygen sensor code.. running a b20 with pr4 ecu. the o2 sensor wasn't hooked up today, so I hooked up the o2 sensor today.. thought it was fine then i got the code again. it comes up after driving for a while. does the pr4 read two o2s?

 

no it doesnt you just probaly need a new o2 sensor. this happened to me with my d series engine

 

I assume you reset the ecu after you hooked the O2 up, right?

 

yes of course. the battery was unplugged the whole time.

 

it is the actual o2

I was running this ecu also for a while

and just bought a new one two weeks ago and it runs like *** but no code

dew to j's racing test w/o 2nd o2 u know

damm OBD0 that is why I am redoing stuff and converting to OBD1 Hondata


and well I got the o2 if u need one
it is a bosch like I stated before two weeks old
