06 TJ 02 Sensors ALL show Codes P0032 P0038 P0052 P0058

2006 TJ - Started with a check engine light and a code for only 1 Oxygen sensor, which got replaced, code was reset and the check engine light went out.

3 weeks later the check engine light is back on and Now ALL 0'2 Sensors show Codes: P0032 P0038 P0052 P0058.

An initial look found one of the battery cables cracked, now replaced. Check engine light went out. Started the JEEP a few times and light remained out. On about the 6th time, check engine light came back on - still showing all the codes for the O'2 sensors (Heater Checks High - All 4).

Has anyone got any ideas short of replacing the PCM?

ground G105 is common to the heating circuit for all four O2 sensors
its located near the left engine mount according the the FSM, yet a diagram for the grounds in the same manual show it somewhere near the oil filter on the right hand side

Before you get too advanced, have you performed SL 25-001-07?

Does your CEL, key on, no start, flash after 15 seconds for 10 seconds before going back solid?

Yes.

I would perform the bulletin first because it changes the ground path I do believe. In any case it completely cured all manner of O2 sensor issues I was having, COMPLETELY!

It might not be your issue but do the easy things first and the bulletin needs to be done either way.
