I am running a b16a2 in my 94 teg. im using a DC sports header. i just recently picked up a virgin obd1 p30 computer and the CEL is on and calling code 41 (Oxygen Sensor Heater) i have come to the conclusion that this is part of the oxygen sensor, correct me if im wrong but the p30 computer is looking for 2 o2 sensors, is there a way to fix this problem or do i just have to deal with the light and the crappy gas miliage?

 

why dont you get 2 o2 sensors...?

or are you running the Dc headre with only 1 o2 bung?

if thats the case get another o2 bung welded in the spot you need it

 

1 bung, and only 1 plug in the wiring harness...i guess my main question is dose an obd1 p30 use 2 o2 sensors?

 

i think obd1 uses one 4 wire o2 sensor,and obd2 uses 2 4 wire sensors.....
i am not sure though....

good luck

Yes. One O2 sensor. You could be seing a problem with the ECU or the O2 sensor itself, try it with another O2 sensor and double check your wiring. A loose or missing connection could cause this also..

 

i got a new o2 sensor i just wasent going to install it if it was a 2 sensor system because the new sensor might not fix it. now that i know im gunna go install it now =)
