Id check the fusesrelays having that many triggered at once sounds like an electrical problem.
check the wires at your sensors. sounds like thayre shorting to ground somewhere. i read on a subaru forum not long ago about this happening and the guys wiring on his airfuel sensor and o2 sensor were melted and shorted.

i dont believe there are any relays but there are fuses. look in the fuse box under your hood. youll find the fuse(s) in there. if you had a bad fuse you would be getting a no signal code for you o2. look at your wires for any damage.
An update and review of all my findings on this thread I installed the Airaid CAI and throttle body spacer back in the winter months and have been doing great with my 06 jeep wrangler Rubicon. I re-oiled the filter and drove it for a few days and everything was fine. At the beginning of the summer I took it down to the coast in Texas and my check engine light came on. To this day and then the engine

Its running again. I disconnected the battery to clean some corrosion. I hooked everything back up and tried to start it. No go. After putting everything away I tried it again just to see. It fired right up just like normal. Before turning it over I checked the codes. It was showing p0038 and p0058. After it started and idled for a while I shut it down and checked the codes again. Back to p0032 p0038 p0052 and p0058.
hmm actually the codes are as follows P0300 P2096 P2098 P0032 11 O2 sensor heater circuit voltage high P0038 12 O2 sensor heater circuit voltage high p0052 21 O2 sensor heater circuit voltage high So actually these codes relate to all O2 sensors. Both front sensors heater circuits are reading high and rear right sensor heater circuit high and reading lean. But The rear left only lean not heater circuit
for other circuitry problems but am scared of blowing the sensor circuit by continuity testing the wrong pins (cant find a pincolourmeaning layout for the JK O2s anywhere). I pulled them all out they are not clogged or damaged. Is it looking more and more like the PCM is playing up Im the third owner and warranty is long gone anyone know the cost of a PCM do u no what this guy was doing with the jeep

Went by local independent guy that has worked on Chryslers for 30 years. He suggested I look for a loose ground wire under the dash. Threw six codes besides speed sensor. I am going to edit in case anyone ever looks for this. Threw all four O2 sensors port injector lost communication with side restraints... in order below . He recommended I check for a loose ground and even if they were tight I should
they are saying o2 sensor heater circuit high p0032 is sensor 11 p0038 is 12 p0052 is 21 and p0058 is 22 so all four sensors are showing the same thing. Probably not all four sensors have gone out so it must be something else triggering fault codes. also intermitent so am going to have to try to figure this one out.
alright OP here had the same issue today super hot day of driving so same start to my story but this time i threw some codes up p0508 p0201 p0032 p0038 p0052 and p0058. thats a lot of codes and i believe the p0201 has to do with the PCM. so im gonna guess a bad computer. any other thoughts would the crank or camshaft position sensor blow a PCM or am i right in thinking the PCM is causing the sensors to flip out
Well we tried to flash the computer tonight by disconnecting the battery and touching the wires together but the codes came back on in about 2 minutes... Heres the codes its throwing... p0052 P0032 P0038 P0058 Looks like theyre all heater circuit high voltage...what could cause this on all 4 at the same time J.
P0032 Oxygen (AF) Sensor Heater Control Circuit High (Bank 1 Sensor 1) - DTC Code p0052 Oxygen (AF) Sensor Heater Control Circuit High (Bank 2 Sensor 1) - DTC Code
P0135 is the exact one mine is throwing right now....unless you know the exact code with an O2 sensor you are taking shots in the dark. Here are the codes that deal with O2 sensors P0030 HO2S Heater Control Circuit Bank 1 Sensor 1 P0031 HO2S Heater Circuit Low Voltage Bank 1 Sensor 1 P0032 HO2S Heater Circuit High Voltage Bank 1 Sensor 1 P0036 Sensor heater relay problem P0036 HO2S Heater Control
P0032 is bank 1 sensor 1 p0052 is bank 2 sensor 1 Dont know if those codes are both listed in the TJ FAQ in the stickies or not. I checked them here... httpwww.allpar.comfixcomputer-codes.html I know very little about later TJs with the mini cats and more O2 sensors so cant really help more than the codes at the moment.
