I changed my all 4 of my 02 sensors, because I got all 02 sensor codes faulty. Yet my car is still going into limp mode. And the codes haven't gone away. Do I have to reprogram it?
Was it going into limp mode before you changed them? Do you have any other codes besides the O2 sensors? It would be highly unlikely that all 4 went bad at the same time. Was any other work done like a clutch change?
On your re-install you may have plugged the sensors in wrong, sensor to sensor feed to feed. Since you had those codes before you did the change my guess is you blew the O2 heater fuse which controls all four heaters.
It was doing it months after the clutch job, I did the clutch replacement myself. I was driving to work and the car went into limp. I got codes read at autozone. the cords are connected correctly. Only codes I have are just 02 sensors. When I put my clutch and drive shaft back on, I drove it like 2 miles without the exhaust and it went into limp mode. Put the exhaust on and it didn't happen again. Until the day I drove to work.
TPS is the throttle sensors and they are the most common cause of limp mode without codes. Now anyway for years we could count on codes, but as the sensors age and likely have a new way to fail we see this often.
The fuse is in the fuse holder in the Ebox and is F3. You did not include any info on your car or even location to give a hint but this is for a US car after 09/2000.

Alright fellas thanks for all the info, I just swapped out the 5 fuses in the circuit. I drove it 3 miles and it didn't go in limp mode. I live in bum a$& Alabama, bought the car out of Texas in October. It's an 01 with 123k
