2003 Ford f-150 4.6, o2 shows bad, bank 2 sensor 2, won't smog
I have an 03 f-150, Check engine light is on. Replaced o2 sensor, MAF sensor.
Clear the CEL, but the first time I kill the truck and start it back, within 2
minutes the CEL comes back on showing o2 sensor, bank 2 sensor 2. Checked
vacuum hoses, wires, etc. What should I check now?
You state that you replaced the O2 sensor, did you replace the rear one on the dr side?
