Code PO133

[deputydaddy]

Ever since I got my Explorer last summer, I get this trouble code. I replaced the O2 sensor, plugs, and wires. I reset the computer a montha go, drove it on a trip, and no code. I get back into town, drive it in town for 2 days, and the code comes back. Any ideas out there?????

what is a PO133?

PO133 is the check engine light trouble code. If you have a scanner, or get it read at autozone, that is what the scanner lists as the code.....

Since you replaced the O2 sensor, check the wiring from the PCM to the O2 sensor and also check for exhaust leaks near the O2 sensor.

i know what a DTC is, i was just wondering what that particular one was. in this case, its an o2 sensor code

dogfriend: im gonna agree with you. i say if you put in a brand new o2 sensor on bank 1 (make sure its bank one, cause i replaced 1 on the wrong bank once, which ended up with me having to buy yet another one lol. oh well i got 2 new o2 sensors so then just check the wiring and connection, and make sure they're good.
