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.
As for the engine clicking, I dunno. The V6 engine is known for noisy fuel injectors. The noise though could be many a thing.
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
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?
Thanks!
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?
Thanks!

Personally, I would add a couple of pounds to all four tires, and see what happens. If you still get a light (and you have no nails, etc.) it's the spare.
Good luck!

It's below freezing in Denver and my 4Runner is often a slow starter in the cold, but the other day it wouldn't start at all when it was super cold. The next day was a "little" warmer and it got going, but I started hearing odd plunking and plinking noises in the engine. Thought it might be ice knocking about, but it got worse. (Not like a hard knocking of a rod or anything.)
It was about 17 miles and by the time I got the office, I was sure something was wrong. When I pulled in, the engine died and it just chug-chugged when I tried to restart it. The smoke and smell of burning rubber that started just then told me to give it a rest. (I think on the front driver side of the engine.)
Any thoughts? My theory is that my water pump froze and with a stuck pulley the belt is just burning and smoking.
What do you guys think? I'm not much of a motor guy, but I've monkied around with engines from time to time.
Thanks so much in advance!
I'm totally frustrated!!!!
