My Wife's 2001 4Runner has CEL and VSC lights on. A scan shows P1135 which translates to Bank 1 Sensor 1 Heater circuit.
The car has 104,000 miles.
At this point I have disconnected the front A/F sensor and I measure about 2 ohms heater resistance. I also measured the source voltage and it is about 9.5 volts, measured across the heater pins.
I cleaned and reseated the connector and reset the code but it returns after the engine heats up or after driving less than a mile.
At this point I am in a quandary as to what to do. The sensor has never been replaced so it it probably due but the heater seems to be OK by the resistance measurement. Possibly the element could open up as it heats. I am not sure if this is a possible failure scenario.
I am assuming there is only one forward O2 (A/F) sensor in the 2001 4runner? I did check the rear one and it measured a higher heater resistance which I think is expected.
In checking through internet data on Toyota I see there is an A/F relay talked about. Is there one in the 2001 4runner?
Any help or guidance on where to go from here would be appreciated.
#2551 of 2607 04 4Runner Problems
Jun 25, 2010 (3:33 pm)
I have recently bought a 2004 4Runner SR5 4WD and I am looking for help with 2 problems I am having with it. I do not know much of anything about cars so any help is helpful. When I am driving and press the accelerator I can hear a clicking noise that sounds like it is coming from the engine. The fast I go or harder I press the accelerator the louder it gets. Any ideas? Second problem, I live in the mountains and drive on a lot of steep hills. The traction light in the car is always coming on. A LOT and the engine makes a grinding noise and then sometimes the car starts to beep. It has also staled on me twice when this has happened. If anyone has anyideas please let me know. Thanks

The stalling I have no useful info, but the traction light is probably a sensor going awry. Best bet is to have the dealer tackle the traction light issue. Then if it stalls on them they may also find the stalling issue. They'll have to hook the computer up to a diagnostic tool for the VSC, so it may find the stalling issue too.
As for the engine clicking, I dunno. The V6 engine is known for noisy fuel injectors. The noise though could be many a thing.

I previously posted a question asking if anyone has had problems with their dash lights going on and off. I am having other problems now as well. The air conditioning is stuck on all the time now! Whenever I turn on the fan, the AC goes on. The switch on the dashboard that is supposed to turn the AC on and off still seems to be working, ( at least it lights up when I push it in). Also, my radio has just stopped working as well. I looked for a fuse that is connected to the radio circuit, and I can't locate one. ( nothing in the fuse box labeled "Radio"). I am going to try and get a TSRM from the library to see exactly how to tear apart the dashboard and locate any fuses for the radio, possibly it may have an inline fuse? I will also have to test the AC switch with a voltmeter to see it that is really working. Any suggestions would be greatly appreciated.

I have a 1995 4Runner with 193,000 miles- 3.0 liter V6. The head gasket was replaced at 135,000 by a mechanic. Recently, after driving for 20 minutes I noticed white smoke coming from the engine. Figured I blew a radiator hose somewhere but was confused as I just replaced the two hoses at the radiator and the 6 hoses by the heater core within the past 2 months.
Upon filling radiator, I turned on the car to notice a fair amount of radiator fluid dripping under the car and coming off the area by the front differential. Unfortunately, I cannot see around the differential from below or down from above to eye ball this leak.
If I blew the gasket again, why is there no water in the oil pan(dipstick clean) or why did I not have smoke from the tail pipe? Seems like this leak has to be something else, as the head gasket only has 50k miles on it. Your thoughts and comments are appreciated. buckeyetom
#2555 of 2607 2010 SR5: Steering Wheel shaking at 60 mph
Jul 21, 2010 (6:40 am)
Has anyone else been experiencing steering wheel shaking / vibrating on their 2010 4X4 SR5? I have 3400 miles, and the truck has done this from the start. It becomes noticeable around 60 mph +- 5 mph. Sometimes it is slight, a few times it has been down right violent. Every time it is visible in addition to the odd feeling. Sometimes it doesn't do it at all. I took it back in shortly after buying the truck and they balanced 2 wheels. It went away for awhile, then came back. Took it back in and they balanced all 4 wheels. It went away for a few weeks, then came back.
The service department is normally excellent - I've had my 2002 3rd generation serviced there for 6 years now and have never had better overall service from a dealer. We even drove 45 minutes to purchase from this dealer since we liked their service department so much.
This seems like it might be more than a tire balance issue, but I'm not sure. Is anyone else experiencing something like this with their new generation 4Runner?
#2556 of 2607 2002 3rd Gen SR5 4X4 tight turning
Jul 21, 2010 (6:58 am)
We are also the only owners of a 2002 3rd Gen 4X4 SR5 with 130K miles on it. We love this truck like no other vehicle we've had and other than one recall on something to do with the steering, it has been great with only routine maintenance.
The problem we have now is super tight turning of the steering wheel. It does not bother my wife, but I have bad shoulders and have stopped driving the truck for the most part. It isn't as bad as not having power steering, but it is tough when parking, etc.
The truck does have some miles on it, perhaps there is a routine maintenance item we missed along the way. Has anyone else had this problem and if so, were you able to address it successfully?

I am a bit late on this but i just happened to me on my 1997 4 Runner with 270000miles on it , luckily i caught it right away and it was the Crankshaft sensor which i had to change and eversince no more problems.

Water pump possibly?
