My ecu is throwing a bad o2 sensor code but I not sure which of my 2 sensors is the one thats bad. So my question is: Is there a simple way to check the o2 sensors to see if they're ok or not? voltmeter? Thanks in advance.

 

bump sukahs!

 

the one wire o2 sensors are dirt cheap.

what kind of car do you have?

 

it's a 90 hatch with a b16 swap. i ordered the sensor from ebay for like 30 bux and it took them almost 3 1/2 weeks for them to ship it to me. I just want to make sure i replace the right sensor the first time.

 

the b16 uses the same sensor as your car does in stock form.

you can get one for your car from advance auto. $40 for the direct plug in, $17 for the cut and splice universal ones.

edit: btw, that's if you're still obd0
