I hooked a scanner up to my truck today. The truck didn't have a check engine light. It had 1 stored code.........


P1157 HO2S Bank2 Sens2 Lean Sys or Lo Volts


Heated Oxygen Sensor? What could have triggered that since it doesn't have any O2 sensors?

your generic scanner, or misloaded info on the scanner

or the bulliten for false codes but to pull the o2 sensor your scaner is fubar

I used a predator programmer to pull the code. I have access to a Tech2 so I suppose I will use that next time. Well I cleared it so I will see if anything else shows up.
