I just had all 4 brakes replaced. What does the trac on, trac off and tire pressure lights on mean?

I recently had O2 sensor replaced along with ignition module, yet, the transmission seems to slip alittle or take a little longer to switch gears.

Help!

Trac on means your trac control is on and the same for off.The transmission problem can be several problems.check your fluid.(the only way to do this is to drain your transmission.it will take 6 qrts bone dry.Check your transmission filter.check your sensor in your air intake.if none of these fix your problem take it to a shop to see if tour transmission powerbands are bad you might need a new transmission.

2008 Lexus ES 350 low tire pressure warning light


1) go to a gas station with an air pump. Unless u have an inflator/compressor at home with the tireattachment

2) lower all 5 air pressures including the spare in the trunk to maybe about 28 PSI

3) now reset the TPMS (on the 07 there is a button to "calibrate" the TPMS and it is located under the dash. I presume it is the same on the 08.)

4) now bring the pressue back up to 30/32 or whatever it says on the door area


If this doesn't work, it is possible u have a defective TPMS
but my bet right now would be that someone "calibrated" the TPMS to the current tire pressure so the light is constantly on. It happened to me before when my daughter was messing around and hit that button.

Why is my trac off light on


It is the anti lock brake system. First, look at the ABS. It will come on for a bad wheel sensor or broken wire. This will also throw the trac light on. ABS is on because the computer senses the one tire is trying to stop or lock up. this releases the brake pressure. On the traction light(which should also throw the ABS light), one tire is spinning faster that another. This can happen on gravel, sand or snow/ice. When you turn the key on, do you have an ABS light on, then goes off? Same with a trac light. If you do, then you have a bad wheel sensor. Scan it and replace it.

Low Tire Pressure Light, ABS light, Trac Off Light and Service Traction Control


I assume this is a Ford vehicle. Start by having the rear axel serviced At the dealership. There is probably metal dust on the magnetic speed sensor, that triggers off of the ring gear inside the axel housing, causing the fault warning lights on the dash. Run an OBDII scan with a print out while at the dealer. Of coarse fix the tire.

I don't understand the whole traction light thing. my car always says trac off-except when it says low trac and slides like it's on ice.


TAKE CAR TO A GARAGE OR DEALERSHIP HAVE THE ABS BRAKES AND TRACTION CONTROL CODE SCAN.YOUR ABS BRAKE SYSTEM WILL COME ON ADJUSTING BRAKE PRESSURE TO AVOID A SKID.THAT WHY LOW TRAC LIGHT COMES ON. MOST OF THE TIME WHEN YOU SEE LOW TRAC LIGHT DRIVING ON DRY ROADS PROBLEM IS IN THE ABS BRAKE UNIT OR BAD WHEEL SPEED SENSOR.

I have 3 sensor lights that came on at the same time. The brake light,tire pressure light, and the ABS light(I think). A friend had a portable diagnostic computer and plugged it in. No problems...passed....


there area magnitude of things that can be the issue here. I wil take a chance here and say that there is an issue with a couple of sensors. This situation involves 1. The brake light sensor (which indicates that i brake light bulb is faulty) 2. The Tire pressure sensor (which is the tire pressure) and 3. ABS sensor ( Which i would associate it with a wheel speed sensor)

You should check the tire pressure, and correct it. Check the bulbs on your brake light and replace as necessary. Then check for a torn or broken ABS sensor, which are located on each wheel,

When the vsc trac light comes on my 2003 Toyota 4 Runner, what does that mean?


As long as it does'nt stay on it's doing what it's suposed to be doing which is saving you from going out of control. It'll come on more often if you drive like hell, run with low tracktion tires or worn out ones and if the air pressure is low. If your tires have over 80,000 miles on them even if the tread is still good their bad tires as their skating along and the trackstion system is working hard to keep the car under control. If the tires aren't al the same size it'll do it to. ( fronts worn out backs still with tread.) Mis matched tires too. Ifthe light stays on other light's are bound to be coming on too the ABS light the brake light, and even the engine light as their all involved in traction control.

I have a 2007 ford explorer sport trac had it serviced they checked tire pressure and now low pressure light wont go off. All tires have same pressure


Are all the tires the max pressure? They should be. If nothing else, inflate to correct pressure then disconnect the negative battery cable for 10 minutes and put it back on.

There's a little light that says "low trac" that goes on when i turn on my 1998 chevy cavalier.... what does it mean??


means the traction control module is bad. That light is suppose to come on when you lose traction to let you know the traction control is kicking in.
