With the engine cold, turn the key to on and look very carefully using a flashlight if necessary (no droplights) There is no "safe" fuel leak. Since the engine will not start, I'd guess that the leak is on the supply side fuel line. Once you find the leak, then you can begin to figure out what needs to be done to correct it.

Codes p0125 and p1133 and p0175 on toyota 4runner 1999


Hello Danielle ---- A code P0125 may mean that one or more of the following has happened:
  • Insufficient warm up time
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty coolant temperature sensor

    The simplest thing to do is to reset the code and see if it comes back...If the code comes back, the problem is likely going to be the result of the above causes (faulty thermostat, faulty ECT sensor, or a low coolant level).


    A code P0175 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled
  • There could be a vacuum leak.
  • There could be a fuel pressure or delivery problem

    Possible solutions include:
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Clean the MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect fuel lines for cracks, leaks, or pinches
  • Check the fuel pressure at the fuel rail
  • Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced.
  • Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

    With the P1133 code, this is almost always pretty cut and dry. You will need to replace the bank 1 air/fuel ratio sensor.

    I hope this helps, Happy New Year...

I have a terrible Power steering leak on my 93' Toyota 4Runner 3.0L V6 and i can't figure out where its coming from. It has leaked for years but only a little bit. Now its like the reservoir empties in a...


To look for a fluid leak, first you should have the car washed thoroughly all around the steering rack and the pump, then inspect it from the underside with a good light looking at the hoses coming from the pump to the rack, the couplings and the crimped unions of the rubber and metal tubes for leaks.
If the leak comes from a coupling, that may be a bad Oring.
For the defective hoses, you can choose from buying new ones or have them repaired in specialized shops that have the tools to make the crimped unions.

2006 Toyota 4runner sport 4.0L V6 2wd bottoms out too easy on front.


Hummmmmm........ either:

(1) Your front struts are worn out or leaking; or,

(2) Your driving style is too aggressive or loads too heavy for your stock suspension to handle.

Jack the front of the car up and remove each front wheel. Look at the strut body to see if there are any signs of leaking fluid or if anything is broken or otherwise amiss. If the struts are leaking, then I suggest you replace with something other than standard replacement Monroe shocks (either Blistiens or Ranchos). If the struts are not leaking, then maybe your driving style is too aggressive for the stock suspension. If this is the case, then upgrade as necessary or change your driving style. Front suspension upgrade would start at $700 and go up from there depending upon the modifications.

I have a 1991 toyota 4runner V6 4wd. Lately driving my toyota 4runner around its been kinda guttless and its getting horrible gas mileage, like below 8 mpg! this is not good, my truck is running kindof...


Have you tried changing both of the fuel filters? If they are clogged your power will go down and your gas mileage will go down. I'm not sure about the smell of gas, but new fuel filters really helped mine.
