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!

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

Guys and gals. Inflating your tire pressure to MAX that is rated on the tire does not give you benefits. It will NOT improve handling. Imagine a wheel made out of diamond, and one out of rubber. The harder the surface is (overinflated) the worse handling you will get. You will lose traction as your tires are making less contact with the road. The tires should be inflated based upon the weight of the vehicle, not the MAX pressure.

You do NOT want to inflate your tires to the maximum pressure on the tire walls. This is a pretty common mistake. The pressure is based upon your vehicle and this info is inside the door jam on the drivers side. Setting your tired to the max pressure on the sidewall of the tire will wear out your tires faster, cause poor handling and will also not allow you to brake as fast.

We'll have to agree to disagree on this one. What's posted on the door jam is for the tires that came on the VX from the factory. After replacing those, you should always follow the recommended pressure rating molded into the sidewall of the tire. The tire manufacturer knows the optimal pressure for performance/wear/safety, not the vehicle manufacturer.

That is absolutely WRONG. The recommended pressure is 29PSI. Tires indicate the MAX that the actual tire can be inflated to. Inflating your tires on the VX to the MAX tire pressure listed on the sidewall is not right at all. This will lead to poor handling, rougher ride and tires wearing fast.

Come on guys, this is basic car knowledge.

I am surprised at how many times I take my VX in for an oil change and they actually inflate the tires to upwards of 40 PSI because of the sidewalls max pressure listing. I never take my VX back to places that do that.

X-2...

This theory(inflation to max pressure) also doesn't address the fact that a lot of folks around here are roll'n larger than stock, off road type tires, that have a larger internal volume, which in fact, will require slightly less pressure to be properly inflated.

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.
