Toyota 4Runner Maintenance and Repair

    it is in the manual. I'll try to check it tonight and point you to the page.
  • nedzelnedzel Posts: 787

    I've got a 2003 4Runner, so my manual may be different than yours. But the information is in my manual. It took me about 5 minutes to find it. In the 2003 Manual, it is in Section 1-5, Operation of Instruments and Controls, page 123. It reads, in part:

    "You need to reset the light after the engine oil replacement. Reset the light by following the procedure below:

    1. Turn the ignition key to the off position with the odometer reading showing.
    2. Turn the ignition key to the on position while holding down the trip meter reset button. Hold down the button utnil the light goes off. Before the light goes off, it illuminates for 3 seconds, flashes for 2 seconds and illuminates for 1 second."

    I'm sure the same information is in your manual as well. Unfortunately, the index in the manual is not that great.

    Just recently I had come to find that my starter on my 2000 Toyota 4 Runner. I am not very mechanically inclined but recently have tried to do maintenance rather than paying a mechanic to do it. I went and purchased the starter but once I got underneath the carraige, I became frustrated as I disconnected the starter but realized that the two bolts that hold the starter are quite a pain to get to, and even more to loosen. It appears as though I need to remove part of the exhaust pipe that goes to the muffler but am a bit unsure. Any tips or advice would be helpful. :confuse:

    I have a 92 4Runner with a new engine(65K) so they said.Right after new engine was installed the truck was kind of sluggish and lack of power, I checked the timing and it was set way too low(8) from the recommended from factory. I raised it a bit to 12 and the truck gained some considerable power, but the gas consumption still the same. It is using too much gas like 5 miles a gallon. Someone mentioned to replace the O2 sensor and the heave gas usage would stop. It is a bit expensive part to be guessing if it might solve the problem, all the tune parts in the truck are new, so that brings me to this forum to get new suggestions or ideas where to start.
  • Have a 1999 4 runner limited. New issue that sometimes the electric lock on the drivers side locks and sometimes it doesnt? Sporadic problem, cant see any pattern. Any ideas?

    you don't have any dash lights, right?

    It could be a plugged cat if power and gas mileage are down.

    You should be able to get O2 sensors for fairly cheap, like $20, and they were right, that could be the cause of heavy gas consumption too, although that would not decrease power. Now that you have the timing at 12 degrees, do you feel it is as powerful as it ought to be, or still sluggish? I assume this is a truck you had for a while BEFORE the new engine was installed, right?

    Thanks for writitng, yes I have owned this truck since new and I love it except for the part when the engine went bad thanks to Jiffy Lube. By increasing the timing power is up but not like it used to, there is a bit of sluggishness still. I called the dealer and couple other places for the O2 sensor and they all have it over $100 bucks, where can I find it for $20?

    Sorry for the dalay but not looked at this site in a few weeks. The problem seems to be in Toyota's design. I think they made the system read higher mileage in order to entice test drivers to buy that particular vehicle since it is showing higher mileage than on the window sticker. Mine shows higher mileage by quite a bit and it is allways 86% lower than actual displayed mileage. Such as, when the computer shows 19.00 mpg, we are actually getting 16.34 mpg.

    I also noted that I reset the average speed to zero and set the vehicle on 60 mph on cruise control which it maints accurately, and the average speed shows 58 mph! This leads me to believe that the odometer reading the computer gets is less than actual which could account or the error. Of course, Toyota denies any problems in this system and will not investigate it. I intend to file suit against Toyota and the arbitration company who refused to test drive the vehicle during our hearing!

    In my experience, the mileage computers in many cars are not that accurate. My 2000 VW GTI's computer also overestimated mileage by 1-3 mpg.

    I will be very surprised if you win a lawsuit over this.
  • jmtreetopjmtreetop Posts: 130
    I have had similar experience in every one of my vehicles. The mileage has overestimated by 1-3 mpg. I don't think that the computer is intended to be an actual, but rather just an estimate.

    Even at my dealer O2 sensors aren't $100. What's up here? The last time I bought one was a couple of years back, could they have gone up 50% in that time? At AutoZone they are like $29.95 if they have them in stock, which is admittedly rare.

    Hi there,
    I hope sombody can help me.
    I have a problem with the code for the radio, I know that I can go to the Dealer but if somebody here knows how to reset and set a new code I would be thankful.
    My 4runner is 1994 SR5 V6 :confuse:
  • Hi, I'm new at this so bear with me please. Does anyone know the procedure, or how to "program" a key for an 03 4Runner? I just bought one and the guy gave me two keys. He said the spare would unlock the doors but it won't start the truck until it's been "programmed'. He said he was told some sequence to go through, but it had to be done in a given amount of time and he could never get everything done in the alotted time. The local Toyota dealership (thieves) want forty bucks to program it. Sounds like a scam to me. Any help would be greatly appreciated.

    I agree, good luck with it. My mileage computer is overly optimistic too (about 10%). I've never heard of one that under estimates the mileage, much less accurate.
  • My son has a 95 4Runner. We were told this year was known to have that ticking sound. I am not so sure as the engine blew last week.

    Sounds like an interesting lawsuit!?

    I would not expect the computer to be exact but rather within a 5% error range which is fairly typical of all cars I own. Buy a GPS or 2 and you will find that most cars typically overread slightly on speed and also on the odometer. My BMW has a 3% odometer and a 6% speedometer overread at speeds above 40MPH. It helps in keeping me out of Highway Patrols sights. Remember that if you change tire size, or any gearing you will also need to either recalibrate or account for that change.

    My 4Runner (2005 V8 4WD) appears to be very accurate with speed and odometer. The computer is optimistic by about 2 MPG, but I just adjust for it. It's not a Cessna airplane so if its a bit out it is of no great concern.

    Be aware that GPS's also have slight errors which typically relate to reception so they may also contribute to the error if you check it this way.

    I have a very annoying problem that seems to be getting worse in that the vent/AC fan has begun squeaking constantly when the fan is turned on to any level. I assume that it needs to be lubricated but I'm not sure if the fan is accessible to me without having to tear out the dashboard.

    Anyone ever have this problem before and is the fan easy to get to? It seems to be somewhere in the area behind the radio in the center of the dash? At least that's where the noise seems to come from. What would the proper lubricant be, dry (graphite) or wet???

    Thanks for any help!

    Does anyone know if a tailpipe extension leading exhaust to the side of the car eliminates the problem of the sulfur smell with the back window down?
  • steverstever YooperlandPosts: 39,993
    Check the Sulfur from 2003 4Runner discussion too.

    Does somebody have the owner's manual? there is a section that refers to the security of the radio, and the procedure to enter the code, can somebody type those instruction here. I don't know, but maybe the reset procedure also is there.
    advise please.
