Hey folks received these codes for the 2nd time after clearing them once p0135/p0141/p0155/p0161 after approximately a dozen start-run cycles. Seems to be pointing at needing to replace the precatalytic exhaust assembly since all 4 O2 sensors failing at once seems unlikely. There are mentions of damage to the wiring harness as a potential cause for this condition and a TSB that addresses the matter if no damage/faulted parts are identified: https://www.tsbsearch.com/Jeep/25-005-13-REV-A .
06 LJ, 6spd, 111,000 mi, 2nd owner of 14yrs, no perceived performance or gas mileage degradation, runs well, this is my daily driver with minimal off-roading beyond 2 tracks surfaces or the beaches of COROVA.
Any insights or recommendations are very much appreciated.
Happy Holidays!
