ok i have a 00 hatch with a b16 in it. i ran the secondary 02 sensor to the ecu and i am using a test pipe with a o2 simulator(mechanical not the electronic one). once in a while i will get a cel (code 1). if i reset it, the cel will go away but come back on later. i know i did the wiring right. could the sensor be going bad? help please.

 

anybody?

 

wouldnt a code 1 be your primary o2? i just checked the ecu stickie at the top and it says code 1 = o2a

 

i did not know if it was the primary or secondary.my haynes book just says its a o2 heater circut problem.

 

check your primary, from my understanding those mechanical simulators work rather well.

correct, code 1 is primary o2

 

CEL 1 = O2 signal. meaning not the heater.

which means i need a new 02?

 

yes... or the wiring has a problem.

 

well people i put another o2 i had laying around and it has not thrown a cel. but another code came up and it was map sensor.
come to find out the map sensor was good. i forgot to put the o-ring under it.lol
