2002 Camry LE V6 gives me code P1155

[2002Camry]

So the check engine light on my 02 Camry V6 (made in Japan) with 183,000 KM was
on and someone check the code with the scanner and it was showing P1155.

Can someone tell me what can be the problem and how much it costs to fix?

I think there is a TSB for this if I am not mistaken:
# TSB #EG01403 -- MALFUNCTION INDICATOR LAMP ON WITH DIAGNOSTIC TROUBLE CODE
P1130, P1135, P1150 OR P1155. *TT (NHTSA ID #10004510, OCTOBER 03 2003)

Any help would be appreciated.

Thanks

Could be 02 sensor(usually the culprit) or A/f sensor.
