Question about 2006 Lexus Is 250
Low tire pressure light and check vsc message on
Posted by Anonymous on
Stuck in 3rd gear because you are on safe mode.
That's part of Toyota / Lexus technology to give you advantage to drive to mechanic without towing your car.
To get it shifts again do this:
Reset your ECU by pulling negative cable off your 12 v battery.
wait 5 mins then connect your negative cable on your battery.
you also need to scan your car to find out the problems.

SOURCE: the VSC and Check engine
Toyotas and Lexus cars have some unique feaures. If your fuel cap is loose or the O2 sensors on the exhaust are faulty this results in an emission problem and the engine computer unit (ECU) engages the check engine light and disables the VSC (the VSC light comes on to warn you that it has been disabled). However you have p0500 code which says the car has no speed sensor signal. The seed sensor is located on the side of the final drive from the transmission and its job is to measure the speed of rotation of the output shaft. The ECU will compare the signals from this shaft along with the speed sensors in the wheel hubs. If there is a difference between these signals the VSC is engaged to apply braking effort to which ever wheel is slipping (running faster) than the other or that the transmission speed sensor would warrant.
So you either have an emission fault has fed back to the VSC and speed sensor missing (p0500) condition, or you have a faulty sped sensor which has tripped the VSC light and in turn the CEL.
Check your fuel filler cap is on tight, turn radio off and disconnect the negative lead to the battery for 5 minutes (this should clear the ECU memory of the code error). If p0500 error and CEL and VSC lights come back on then check the electrical connection to the speed sensor. Ensure it is clean and making a good contact, check the wiring for continuity. If everything else looks good consider changing the speed sensor.

ur vsc light will come on whenever you have a check eng light on. best thing to do is bring ur car to a local and have them scan ur car. your car should still be under factory warranty any repairs wont cost u anything.
just from my experience a 2007 ES with a check eng light is most likely a faulty a/f sensor or a loose gas cap

Testimonial: "Knowledgeable expert...found the button (but unfortunately did not fix problem--maybe shop messed up a sensor in the tire)"
SOURCE: 2004 Lexus Ls 430 Low tire
My 2004 Lexus LS 430 has had the light come on several times, even after changing all four tires. There are no tire pressure sensors on my four tires. I was told the car computes tire rotations and since a low pressure tire takes more rotations than a fully inflated tire, the computer puts up a message on the dash.
To reset/turn off the message, put the emergency brake on, start the car and reach below the dash to the right side of your steering column until you feel two buttons in a depressed area under the dash. One button turns on /off your smart key and the other will turn off your tire low pressure message. Depress and hold until the message on your dash goes out and you are good to go. I know this works, I just reset mine a few minutes ago.
