Code P0155 and P1151

[FORD19]

i have a stock 1997 Ford Ranger V6 4.0L XLT. I got two trouble codes, P0155 and P1151. P0155 is O2 sensor circuit malfunction (bank2 sensor1) and P1151 is lack of upstream heated O2 sensor swith-sensor indicates lean. What should i do first to fix the problem and possible solutions?

O2 sensor is probably faulty. To verify, hook up a scanner that has the ability to display all the parameters in real-time. By watching the sensors values in comparison to one another you will find your problem. They should oscillate between .2v-.7v at idle on an engine at full operating temperature.

Your truck looks amazing. What size and width are the rims that you have? Also what size lift kit do you have on it?

Thanks...in the pic it has a 3" body lift, and either a 4" or 6" (cant remember) skyjacker suspension with 33x12.5 BFG A/Ts on Eagle Alloy 15x10 wheels. Ive had every size skyjacker lift made and have recently upgraded to the 8" springs. It will get 35" tires once I get back in the states from deployment.
