Where do the wires for the O2 Sensor, Evap pressure sensor, and TPS/Pedal Position Sensors join?

Asked by Apr 18, 2015 at 01:07 AM about the 2005 Kia Sedona LX

Question type: Maintenance & Repair

Where do the wires for the O2 Sensor, Evap pressure sensor, and TPS/Pedal Position
Sensors join? I'm getting Check Engine Light codes P0154, P0454, and P0122, which
are for the O2 sensor, Evap sensor, and TPS sensors.  Each could be caused by a
loose or faulty wire or connector.  I'd like to check those connections, connectors and
wires.

Thanks,
Wes

They don't all join together in one common area. I doubt it's a loose wire. For the O2 sensor, you have to figure out what bank it's on. Usually when reading the codes it will say bank 1 or bank 2 . The Evap box is usually jammed way up between the spare tire and the gas tank. Probably a failed vent solenoid. Here's a video on the TPS. Very easy to locate...... https://www.youtube.com/watch?v=JRwUK2Iem9s
