URD o2 sim + water = code? maybe?

basics: 2006 TRD off-road 4.0L with Doug Thorley LT and o2 sims, code was thrown

so i was wheeling through kane creek this past weekend in moab and my check engine light came on. at first thought, we went to the gas cap to make sure it was on tight and it was loose. so we thought that must have been it and just need to get the light reset. wrong. just took it in to my buddy at toyota and the code came from iirc bank 2 sensor 2 (downstream o2 sensor). i remember hearing that some people have had issues with the sims and running through water.

has anyone had this issue?

and if so, how have you fixed it?




thanks

 

Are you an xrunner?

Edit: Never mind, gotta learn to read better. It might just be very well as simple as a bad O2 Sensor if she got dumped in water. first thing I'd do is look underneath and make sure the sensor wires are all still attached in the correct places

 

yea i'll be taking apart the connections this weekend to see how everything looks...hoping that it's not the sensor and just a connection issue (that's repairable!)

 

awesome, just read through your thread there...thanks! i'll try out that zip lock bag idea too for future water endeavors

 

got my ultragauge installed and these codes were the culprit

P0158 - 02 Sensor Circuit High Voltage (Bank 2 Sensor 2)
P0606 - HO2S Heater Resistance (Bank 2, Sensor 2)

 

turned out to be a bad o2 sensor...replaced the sensor that threw the code and haven't had an issue since. The sensor voltage has been acting normal again. i put the o2 sim in a ziplock bag and duct taped the seems for good measure too.

 

got both rear sensors for $105 at rock auto so it wasn't too bad but still ain't cheap...figured to get it while i could save a couple bucs on shipping and have a spare for when the second rear goes
