#2413 of 2607 '91 4runner knock sensor problems
Dec 15, 2008 (8:43 pm)
I have a 1991 4runner 3.0 V6 sr5 standard 4x4. I did the head gaskets last winter and gave it a tune up at the same time. The check engine light came on all the time after that, the code that came up when jumping terminals was 5 3 (knock sensor). After talking with the local Toyota techs, the diagnosis was change the knock sensor (and short harness). Last month I changed it and had some other work that included regrinding the camshafts for a little more jam and new larger exhaust done as well. But that code 5 3 is still showing up and it is retarding my timing dramatically. What is this code trying to tell me? All I know is that it is the knock sensor circuit. What should I be looking at to find out what the problem is? What are some diagnostics I need to perform? I am this close to taking it to the dealer but am scared of the costs. Please help.

Another thing I have noticed is that my voltage takes a dive when I put my foot into the throttle, especially at low RPM. The battery and park brake idiot lights come on and everything electrical slows or dims. Could this have something to do with that sensor. I am taking it down for testing the battery and alternator today.
#2415 of 2607 Adjusting brakes on 05 4Runner
Jan 02, 2009 (3:52 am)
I own a V6 2005 4x2 Limited 4Runner. It's getting close to 45k service. The dealer close to my place charge $ 93.00 for the 45k service which include oil change, brake adjustment, fluids check, etc. all minor stuffs. I feel it's too expensive. I usually do oil change on my Camry. I can do oil change on my 4Runner too. No problem.
The question is "break adjustment." I don't see it on the maintenance manual. Do I need that? If so, can I do it myself? How? Can someone please give me some advise how to do it or where to look for the information. I have been looking for it online for hours and can't find any substantial info about adjusting the brakes. I am good with my hands and have some experience fixing brakes on toyota and honda sedans.
Thank you for reading. Happy holidays to all..........

Consider asking your dealer what they do during the brake adjustment. There is no adjustment for disc brakes that I am aware. They might check the pad depth but disc brakes are self adjusting. The only other adjustment might be the parking brake but if it is working ok it should not need adjustment either. Sometimes it is good to have the dealer trained technician take a look at the vehicle. Most dealers offer a complimentary multi-point inspection check of your vehicle when a service or repair is performed. They may find something now that may prevent a breakdown or an expensive repair in the future.
#2417 of 2607 Vibration in Roof of 04 4Runner
Jan 02, 2009 (10:24 pm)
I've got an 04 4Runner with about 69k miles. When I'm on the highway I occasionally get a vibration that sounds like is coming from the roof. At first I thought it was the moonroof visor but I've since ruled that out. It seems to get worse as the outside temperature decreases. Any suggestions?

No but if you figure it out let me know I have the same problem.

Try adjusting the roof rack crossrails toward the back of the vehicle. This also lessens road noise.

Thanks, I will try to pry out some info from the dealers what they do by saying break adjustment.
I think my brakes should be ok since they did 4k service. That time they charge me $65.00, which is ok. But, $93.00? I can't afford it. I don't know why they went up.

Yeah, I would check the roof rack first. For my 05 model, there is a sticker on the rack saying the quietest position for the cross bars. I don't know you have such sticker. If not, check with someone who has 05 model and try to adjust according to it. And I would make sure the screws of the cross bars are tight.
#2422 of 2607 1993 4Runner won't go in reverse when cold.
Jan 20, 2009 (6:07 am)
My '93 4Runner has been slow getting into reverse when cold. This has been ongoing for the past year. Sometimes it just takes a few seconds, and then it locks in and goes in reverse.
Yesterday, it wouldn't go into reverse at all. I took it to the mechanic, and he said the transmission needed to be replaced with a used one, at a minimum cost of $1,100.00. OUCH!
A few hours later, I was driving it, and it started going into reverse again.
Anyone have any ideas where the problem might be, and do I really need to replace the transmission?
Thanks in advance for your help!
