I finally got the O2 sensors, all four of them that mentioned in here.
and I faced a problem!
one of the sensors in my TJ was ripped off of the wire connector.
What I see now is the following:
1- Sensor connected to the exhaust
2- No wiring on it
3- The wire with connector that connects to it has no connector and just a spaghetti wire.
So, I can replace 3 but the fourth I guess I cannot since there is no connector that can be connected to it.
My question is:
Will there be a problem if I just took off all the sensors (all 4 oxygen sensors) and not connect them at all?
I ordered the OBDII scanner that you once recommended:
https://www.amazon.com/dp/B077F8F6TB/?tag=wranglerorg-20
When I connected it, it didn't work no light at all.
Plus, I connected another one and it didn't connect either.
Any suggestions?
You can't drive your TJ with no O2 sensors, it won't run right.
Technically you can get rid of the post cat O2 sensors (but you would need HP Tuners to disable the check engine light from this), but you have to keep the pre-cat O2 sensors, as they give feedback to the PCM and affect how the engine runs.
As for the OBDII scanner not working, maybe it's defective. You plug it in, turn the ignition to the on position (but don't start the vehicle), and it should turn the scanner on.
