Toyota 4Runner Maintenance and Repair



  • canddmeyercanddmeyer Posts: 410
    Your low mpg is bcuz of the urban driving. My 2003 gets as low as 14.5 city. As for maintenance, just go by the owners manual. If you don't have it then it's available online at Toyota's website, although you might have to register as an owner to see it. Fwiw, change the oil more often - at least every 6 months.

    Hi, i have a 1997 4runner SR5 great truck wouldn't trade it in for anthing else. My engine light is on and I did a diagnostics and its showing the o2 sensors. Does anyone know how many sensors does it have and where are they located? Thank you.
  • I believe there re two O2 censors - the yare not cheap. I am on my way today to get one replaced. I've been driving with my check engine light on for about 1 year now - I know it's the O2 censor. Not a huge deal, jsut lower gas mileage at this point, but it is due.

    I've got 130,000 on my 01 4WD 'Runner w/Sport package and it still runs like it's new aside from the censor.

    If you replace the O2 sensors - go ahead and replace the spark plugs. They have to be pretty bad if your motor was running a rich fuel mixture.

    Hello everyone, New to the forum.

    My wife's 02 HL's CEL, VSC & TRAC lights came on after a wash after a car wash sometime ago. After a couple of days, the lights went out so I figured that a connection got wet and caused the lights.

    Buy a pressure washer about three weeks ago, and wife decided to wash the HL with it. Lo and behold, here they are again on the dash. After two weeks, I disconnected the battery and restored. Lights went away. After a few times of driving, they are back on and the SUV cannot be inspected.

    Any ideas of where a connection might be, that could cause this so I can begin to troubleshoot? (The engine compartment was not opened for the wash)

    Thanks for any replies.
  • Hey. I ahve a 90 4 runner V6 and have the same problem as you. Did you ever resolve the issue??? I am thinking something with the Coil maybe??? The coil resistance in my truck is a little high.. 0.7 Ohms and the FSM specs 0.4 - 0.5 Ohms. Maybe a short??? I also get Codes on my CEL. 13 , 42 and 43

    13 -- No IGf Signal
    42 -- No IDL or NSW or A/C Signal
    43 -- No Speed Sensor Signal.

    Jumping out the plug for base timing doesn't work. (Same effect as not jumpering). I dont notice very much change in truck RPM when I connect the jumper either...seems a bit strange. I Know the timing is "close" because otherwise the truck would run like a real turd rather then rough, hesitate, poor gas mileage and maaad vibration at about 110km/h

    I had Autozone pull the codes and they point to the bank 1 O2 sensor. Some research shows this to be the one at the back of the engine, prior to the cat. I'm hoping that water got into the elec connector and caused a short or corrosion issue. I plan on checking that this evening. If this doesn't work, I'll replace the sensor next.

    Sorry, I don't know enought about these trucks to help with your issue. This is the wifes car and I mostly tinker with my vette.

    I have a 1999 4runner limited, how do I know which tire air pressure to use? The value that the tire says, or the value written inside the driver door area? Sorry if it's a newb question, I wasn't sure as both values are pretty different. (The one on the tire is a lot higher).

    I am looking to buy a '06 4 runner. I looked at one available from my favorite dealer. Test drove it and stopped in a parking lot to check it over. Notice the latch for the rear door was rusted. Tried to check the oil and the tube that holds the dip stick was rusted and could not get the dip st. out. Read a couple reviews about water getting in somewhere and getting the rear rugs soaked. They had no answers or satisfaction from toyota. Any help GREATLY appreciated.

    I own a 2006 LTD V8 with 70K miles, bought new, with no problems at all. Still have original tires & brakes. I have followed the routine maintenance schedule with service provided at a Toyota dealership (essentially oil and filter changes). I have no water leaks, but have not taken the truck off-road. I've driven it through countless rain storms with heavy flooding and no leaks. I would pass on this particular 4Runner and keep looking.

    I bought a 2006 4Runner sport without the owners manual.
    I had a yellow light on the dash come on, it looks like a bottom 3/4 of a tire with an explanation point on the inside. is this a tire pressure monitor or ??
  • boats3boats3 Posts: 42
    None, you need to go to a shop and have them run the codes, personally I stay away from the dealer unless it is under warranty.

    I have an 08 4Runner without the steering wheel audio controls (didn't realize this when I tested it, just assumed it was there...anyway). I know it's a different air bag that goes with the steering wheel controls, but I'm wondering if it's as "easy" as taking off the current airbag, attaching the controls and then attaching the new airbag?

    Has anyone done this or seen it done? I've seen posts where people were able to do it with a Sequoia, but haven't come across anything on the 4Runner. My main questions are:

    1. Is this possible??

    2. Is the steering column/wheel prewired for this? Is it as easy as mentioned above, taking off the air bag and putting in the controls and new air bag?

    Any advice is appreciated.
  • chuck1chuck1 Posts: 1,405
    If you nave to buy a new airbag, it would probably be a lot cheaper to change the stock unit and buy one which has a remote control. You can use the remote in lieu of the steering wheel controls. Those airbags can get very, very expensive......

    You can look at an online owners manual by going to, click on "For Owners" link, then click on "Owners Manual" and register your vehicle.
  • i just had 2 a new starter put on my 94 4 runner. the motor is turning over but i wont start.
  • tech17tech17 Posts: 6
    You could tell when you get into the truck if it had water damage (mold smell) I have not heard of this problem I will checkThe dip stick is a commin problem the tube is easy to replace and im sure the selling dealer would replace before you take it home its caused from the oring being dry and swelling.
  • tech17tech17 Posts: 6
    Its the tire monator lite
  • tech17tech17 Posts: 6
    Get the truck scaned if its a misfire converter damage can accure big bucks
  • tech17tech17 Posts: 6
    You need to know if the trans fluid is world standard I beleave it is if there is no dip stick it is WS and needs no service until 100.000 mi If the injectors are bad the check engine lite will come on A good injector through the fuel tank will do I like the BG products at dealers only Coolant should be tested.

    Bank 1 means right side if it is a v6 You still need to know sensor 1 or 2

    I am taking it too dealer on 26 May 2009 and they are telling me the 100,000 mile maintenance package is going to cost me $1,200. Any thoughts? Besides the Timing Belt should anything have to be changed. Thanx for any help....
  • 2006toy2006toy Posts: 6
    They typically suggest the water pump as well do to its location relative to the timing belt. I had both replaced @110K on a 1994 4-cly Honda Accord that lasted till 188K with no problems before I traded it in for the 2006 4Runner. I got tired of driving the Accord - it's probably still running. If you're not keeping it for a while, then maybe just replace the timing belt to save cost.

    I've 'inherited' a 1995 Toyota 4Runner and need to replace the rear bumper to pass inspection. We want to start with local junkyards, but we don't have many.
    Any easy way to tell what other year models have a (rear) bumper that could take the place of the '95?
  • julietjjulietj Posts: 15
    1990 - 1995 bumpers & bumper ends will fit your 1995 4Runner.
    If you can't find a junked one, they're also available as OE replacements at various auto body parts sites on line.
  • mjdennismjdennis Posts: 2
    First, thanks! (Although I was hoping for a bigger selection of recent years. Can't argue with reality, though!)
    Do you know what changed in 95 that makes later models different?
  • julietjjulietj Posts: 15
    1996 is the 3rd Gen of 4Runners, with a MAJOR redesign! It looks similar, but has an all-new body shell and chassis - instead of the truck it used to be, it shares a chassis with the Land Cruiser. There are interior changes and a new engine, too, which they put in all the the Tacomas at the same time.

    My first 4Runner was a 1998, then I fell under the spell of the total redesign in 2003. I'll stick with this one until the end, though. And I still feel a bit wistful when I see the early trucks on the road ....
