torque on demand problems

[Geo114]

So its been a rough winter and my vx has preformed sort of flawlessly. Its been through deep snow a few times and worked well. Today I went to one of my favorite resturaunts and when I came out and turned on my vx the "tod check" light was flashing. It also appears that my vx will not transfer torque to the front wheels. I understand this could be a sensor problem. Where are the sensors and how to I check to make sure they're working? Where is the TOD box and how do I make it flash a trouble code?

Does any know what the problem could be?
Thanks.

mine did that to it ended up being the power steering pressure switch

Hi geo !


Make sure all tires are well inflated & all are inflated at the smae PSI pressure.

The TOD flashing is common when the tires aren't well inflated & hope is that & not something more serious.

Good idea Gussie!!! I highly recommend using the "Maximum PSI" indicated on the Tire Sidewall Panel as your normal everyday PSI. By using the MAX PSI, it will give you the best MPG, best handling, and longest tire wear. Yes; running Max PSI will also give a bit stiffer ride, but VX's have a normal stiff ride anyways (it just goes with the territory). Try Max PSI (per Tire Sidewall Panel) in your tires, you'll love the difference in feel and response along with savings at the gas pump.

okey dokey.

I check my tires twice a week but I checked them again and they're fine. Is the TOD system connected through the normal obdII port? So if I take it to auto zone can they get an error code for me? Are there certain sensors that generally fail before others? The Vehicle speed sensor is probably working cause the speedo still works and the car shifts smoothly.

If it is a speed sensor how much do those usually cost to replace. I can see them on the bottom of the car so I gotta assume its not to labor intensive to fix one. How do you tell if they're bad.

Thanks guys!

Also, the nearest izusu dealer is 60-70 miles away. I CANNOT get a ride back and I have work and school so it has to be a local mechanic (firestone, ect). I would like to bring them as much info as I can as far as what the problem might be.

search is your friend...

using "tod codes" as criteria, I found exactly what you're looking for...

Okey dokey,

managed to get a code today. Code number 14. So a front speed sensor. I dropped it off at Midas and let them know so hopefully it will be fixed soon and won't cost a fortune.

Hmmm - around my location "fixed" and "Midas" cannot be used in the same sentence.

Good luck.

going to max PSI wont give you all those benifits.. better handling yes.. longer treadwear.. no.. it will wear the center of the tread faster than the rest of tire

at the bottom of the front axle u will find what looks like 2 blue and white electronic valves un screw... disconnect it and blow into the valves... and shake it around.. also clean the connectors. most of the time its just water that gets inside of them.

blow into the valves... and shake it around..

That's how we used to have to fix our Nintendo back in the day.

Geo,

On a lighter note: here's what I didn't do to fix mine:

BTW, TOD Check Light still out so I still haven't done anything to fix it.

Geo114, don't sweat it - mine throws a Code 14 sometimes if I do too much sliding sideways in wet snow. In cold, dry, squeaky snow it's not a problem but if I go out and do a bunch of donuts in wet snow it packs the wheels, brakes, front suspension full of snow. For some reason the sensors don't like that and the TOD light flashes, the VX goes into 2WD and the fun really begins!

You can dry the connectors like Gabilangabby said and that will solve the prob immediately or you can just drive around in 2WD for a while and it will dry out on its own and revert back to AWD. I guess if you wanted to prevent it from happening again you could hose the connectors off with Caig DeoxIT or something of that ilk and then pack them full of waterproof grease. But then you'd miss out on all that 2WD fun - rear wheel drive w/LSD and short wheelbase is very entertaining!

As far as the pumping up the tires to max psi goes - it makes the car FEEL like it's handling better simply because there is less sidewall flex so steering feels quicker, more direct, more precise - but since higher psi means less rubber is in contact with the pavement, roadholding is diminished therefore corner speed and braking ability are diminished. So if you define better "handling" as the ability to corner faster then, in most cases, pumping the tires up to max rated pressure is going to be detrimental to handling, since max is usually far above the optimal compromise between less sidewall deflection and more stick. Of course if you go too low then the tire rolls excessively and you're riding around on the sidewalls in the turns which isn't good for traction either. Go even lower and the bead pulls away from the rim and poof - you got no stick at all!

I’m more of a lurker than a poster... but I was off roading last weekend and got the VX sunk at one point... water in the cab and all.

After drying her out for a bit... got her started and all seemed fine.

Then on the way to work yesterday, the TOD started the flashing and check light is on.

On a note the RPMs at idle are about 2.5k after the commute?

Can anyone point me to the locations (pix if possible) to the connectors for the sensors? That and the location of the TOD control box? I will try the code thread tonight and see what error codes it throws.

Thanks for any help.
