what o2 for ej22

Featured Replies

i dont really feel like spending the at least 50 bucks for a new oxygen sensor and EVERY out of about 10 ejs at the wrecking yard has whole front exhuast removed with o2 so i was curious if its safe to use one off a different car and if so, any ideas? or are used o2s not a good idea :confused:

Used O2's are not a real good idea. They don't last forever. Though you can "burn them out" with a propane torch and get some more life out of them usually.

 

I get the NTK or Walker branded sensors and have had good results with both. Try amazon or rockauto.

ok ill probably get a new when i save up a little for one, not having a o2 wont hurt motor right?:confused: because ive put almost 200 miles on it but now my #1 injector ground doesnt have resistance on the manifold harness so i gotta figure that out :(

Injectors are ground controlled by the ECU. It should not have ground unless its being fired. it should have 12v with the ignition on.

well i just tested one of the black with yellow stripped wires labeled injector ground according to the chart you gave me (f47 24/25 i think ) at the ecu plug, not ecu itself i tested one of the to the injector and got resistance in the wiring and the other didn't so im guessing i have a break in connection. i have power at the injector on ignition, but its not grounding:horse:
