CodesP013A, & P013C..calibration?
Hey, this Jeep is a 2007 Grand Cherokee with a Hemi, I have seen bulletins for ehaust leaks....even very small ones causing these codes. I know the exhaust is good...it's new, manifolds ....all....this code sets when you go over 60mph and do a decel and it sets almost immediately....a 1 trip code. These codes are for both rear o2's. I have seen bulletins for recalibration, but not for the Jeep hemi....for the 300 or the magnum....The o2's work good in this jeep and are new also, it's funny cause both codes set at the same time.....they don't switch from rich to lean in a specified time, been racking my brain I keep thinking it's a calibration issue but the dealers keep telling me ..NO....anyone have any luck with this
