Ses Light: Codes Read.

871 Views 4 Replies 2 Participants Last post by  kjw86ca
Hey guys,

The other day I got my codes read @ Autozone (here in CALIFORNIA! I'm so happy they did it for free...) and this is what came up:

P0052 HO2S Heater Control Circuit High (Bank 2 Sesnsor 1)

PO161 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)

So what does this mean, how can I fix it, can I do it myself, and how?
Any help is appreciated.

This is a 1998 Taurus SE Vulcan

There is a relay that supplies battery voltage to the O2 sensors at startup, to heat the sensors up to proper 600F operating temperature. The relay is probably going bad. Let me see if I can find where the relay is.
There is a 10amp fuse in the engine compartment relay box for the HO2 sensors. Haynes shows it labeled as #27, but I'm not sure if that's the panel number.
Thanks Im gunna look into that. Anyone else??
