Not sure if this got lost. replace the gas cap with a new OEM. disconnect and reconnect the battery and try it. Worked for me.
its a bit early for xmas lights
2005 4.0 5spd auto, New used car lot purchase 9/8/18 195k
I was driving in the rain this morning 60mph. CEL came on plus TC & the other two below it VSC trac & Vsc off , the car continued to drive AOK. Fault code stored for this was P0137 which looks like a 02 sensor.
New sensor on order.
plus the TPS light since yesterday, thats a separate issue
Just for reference I also have the transmission Judder.
anyone want to throw any more crap my way? :juggle:, I will post up any result with the fairy lights.

Had P0137 O2Sensor Circuit Low Voltage (Bank #1 Sensor #2).
swapped out this with a bosch sensor. P0137 gone.
now have P0420 Catalyst System Efficiency Below Threshold (Bank #1).
I ordered 2 rear Denso 02 sensors on 234-4260 + 234-4261 (small 3/4" difference in wire lengths only) and will try them, at the same as having the exhaust checked for leaks.

Do I have a problem?
Guys I think I have the opposite problem than most people are experiencing with the VSC system. I have no skid warning, VSC Trac, or VSC off indicator lights come on with the key in the on position. They have never come on since I have had the 4runner. I do get the ABS light with the key on though. When I lock the center differential the VSC does not show to be turned off and taking corners fast on purpose never shows any vsc kicking in. The owner's manual states that these lights should turn on for a few seconds with the key in the on position. What's going on here? 2004 Limited 4wd V8

I woke up to these same 3 lights on a couple days after I got my 2004. Found this thread and drove down to Autozone to get any codes read. It came back as a p0306 - misfire in cylinder.
Talked to my mechanic and he asked me if I had left the gas cap loose at any time. I had only filled up once since I bought it, but I had left it running while pumping ithe gas. Yes, I'm a moron.
We re-tightened the cap, he cleared the code and the lighs have not come back on as of 400 miles since. I still have no idea what the problem was, but it's not throwing any codes and running like a champ, so I'm just going to keep my fingers crossed.

Actually just the pressure difference sets the light on . As noted if it happens again, get a new OEM cap, disconnect the battery, put the new cap on and clean the area around the caps seating reconnect the battery and should be ok. That's what many of us did and it has worked.

rear Denso sensors did not change squat, Still getting the P0420 .
went to Advance auto parts, brought a pair of 18mm non spark plug fouler fittings $5 to mount the rear 02 sensor in, wiped codes and they have not come back.
I just wanted the abs and vsc & CEL to be OK. :thumb3:
I need check exhaust system for leaks now.

VSC TRAC off button Check Engine light
I let my son use the car and he put gas in and lost the cap. When I went to drive it, all three lights came on. Low and behold it was just the cap. I'm not saying that this could be the situation for everyone, but it was for me. Crazy how a gas cap could do this. I was freaked out!!
That happened to me too. Checking the codes at autozone (or similar) can be a big help.

I had the dreaded CEL and both trac lights turn on about 6 days ago, bought a new OEM gas cap and it went away immediately.

I have an '04 SR5 V6 4WD and I got the CEL, VSC TRACK, and VSC OFF lights that came on today during a snow storm. I did not notice any loss in performance, but traffic was moving slowly. When I got home, I checked the gas cap & it was tight, but I took it and off and put it back on again to be sure.
People are suggesting to unhook the battery cables for 30 seconds but how then do I reset the power windows? I read they will not work again until re-set and I have not found an answer for this in the thread.
I am hoping this will do the trick. Thank you all. :hatsoff:

Exhaust issues
I'm having the same issue in my v8 limited 4runner auto parts store scan said bad rear cat. I know my passenger side manifold is cracked so any recommendations for both manifold replacement brands and y pipe brands. I was going to buy the URD y pipe

How to solve
Solution:
Have her put that back hatch window all the way down, roll it all the way back up. All should be fixed.
This happens on my 2003 SR5 every time I get a new battery.

Hello, similar issue but not eactly - hopefully someone can help on this matter. Recently purchased 2003 Sport and it's showing no lights when the ignition switch is on. I also have no lights when I start the engine. However, once I put it in drive the VSC TRAC and TRAC OFF lights come on. No other lights are on. It runs and drives just fine but I want these lights gone because, obviously, the skid control isn't working.
I stopped at local auto store to run the OBDII code and it came back with the infamous C1336 - zero point calibration of YAW rate sensor undone. It's the only code which comes up.
I ran through the TSB to reset the YAW zero point numerous times but after shorting Ts and CG 4 times (or more) in 8 seconds the VSC light is NOT lit. After turning the ignition switch back on the VSC warning light is not lit so I turn the ignition switch off. I still tried connected the TX and CG and turning the ignition on but the light is still off, it does NOT go through the 4 second on and .13 second blink.
The lights still stay off until I put it in drive...any ideas?!?
