Update: Yesterday morning I went out to my car to clear the code and when I cranked it up, the lights were already gone.

I appreciate the reply. odd as it is the code on the reader was P1135. only thing I have done is loosen and retighten the gas cap and the warning lights are off. who knows when or if they will stay off. the next fill up may cause this again. I'll update as things happen. I have the A/F sensor on order and may wind up replacing anyways.... time will tell.

finally got around to changing the A/F sensor. codes cleared after three starts. for whatever reason the codes would clear for a short bit after refueling. don't know it just happened.
thankfully no problems with the 12mm nuts that secure it. no rust at all.....southern vehicle with clean underbody!!
thanks for the assist folks

I have no idea why a P1135 would clear after refueling. I don't even have a theory.

I have no idea why a P1135 would clear after refueling. The only thing I can think of is that maybe a pending evap code is clearing and causing a retest of all the monitors, clearing the P1135 temporarily. If you get an evap code in the future, that would confirm it. Really, only the evap codes have anything to do with refueling.

I just got the P1135 code, as well. Ordered the new sensor, but can I drive it until the part comes in and I get it swapped?
What are the consequences of driving without this sensor? Bad fuel efficiency? High operating temp?

I am interested in this as well as my truck threw the code this morning and I need to use it until I can get the replacement part (Wednesday). I drive at least 120 miles a day going to and coming from work.

Would recommend driving as little as possible. Depending on how your engine is running (mine was running 2% rich when my AFR sensor went), you could run the risk of flooding the catalytic converter. Someone here on the forum might have a little more information on how serious of a threat this is, but the thought of sending excess fuel into my converter made me a little nervous until I replaced the sensor.
This being said, I didn't realize that at the time and drove for another 1000 miles or so. Haven't seen any real issues yet including an inspection in NY.
On another note for those who will replace this sensor, be weary that the bolts holding the sensor into the exhaust may have completely corroded away depending on where you live. I had to use a hammer and a chisel to break apart the nuts WITHOUT damaging the screw boss that is attached to the exhaust pipe.

AF Ratio Sensor
The AF Ratio Sensor I ordered arrived this afternoon. It only took me a little over 15 minutes to change it out ( I took my time). I disconnected the negative battery terminal and pulled out the EFI fuse before I started. The codes were cleared when I was done and reconnected the battery. The 10mm bolt and 12mm nuts came out pretty easily, I did not even have to spray them penetrating oil. Having a rust free vehicle really helped. The hardest part actually is trying to squeeze in underneath the truck. I should really ditch the running boards soon

Do you how this differs from a Cali emissions 4Runner with 2 cats and 2 02 sensors?...

Trick question, huh? There is no such thing. If it's a Cali two-cat system, it has an A/F sensor in front and O2 in back just like this one. Two O2 sensors means one cat, period.
ONLY an A/F sensor found on the Cali-type two-catters will throw a P1135.

My bad, not a trick question, just an ignorant question....
I went to the dealer and they hit me with $500 quote for the 2 sensors.
$312 for one & $273 for the other. Ouch
They had to look it up by my VIN.

You can get OEM Denso on Amazon at about $200 for BOTH, less if the front is an O2.

No, I don't believe that there is a part number labeled on it. You can go to Denso's website to see what part is correct direct from them.
