Question about 2005 Toyota Highlander

1 Answer

Why Did the Vsc and check engine light come on in 2005 toyota highlander?

When the lights came on I removed and replaced gas cap. I then disconnected the battery and this cleared the lights. Drove car and after 5 miles light came on agin. Did this twice. Got car scanned and got codes p0430 and p 0420. Had been 6000 miles since last oil change. Had oil changed and asked them to check for loose hoses near air filter. They saw no problem. Can you help? Do I have to gat my catalytic converter replaced?

The converters generally fail only after the truck has been running rich. I would not replace them until certain the engine is running properly. There is no harm to the car to drive with these converters. Was there any history of rich operation codes?

Have you scanned both the engine computer and the abs computer? Because it is an abs problem, likely a wheel speed sensor.

SOURCE: Check Engine Light, VSC and Traction Control Off Light, came on after oil and filter change

obviously they did disconnect a sensor while they were working on your vehicle.this will set a code in your vehicle's computer.They call this a soft code since there was not a failure but it just did not sense a signal.After reconnecting it clears the code after so many ignition cycles,meaning turning the key on and off so many times.The code is stored in the computer so it would be a good idea to take it to the dealer to check it out and make sure there are no other problems

SOURCE: VSC TRAC, TRAC OFF and CHECk ENGINE lights

You have to know what code is stored to fix the problem. Toyota's will generally display a Check Engine light, VSC and TRAC light all at the same time, even if it's a simple problem with an oxygen sensor (for example). You can disconnect the negative battery cable for a few minutes, even though you should a scan tool should be used, to clear out the code.

2006 Highlander - Check engine light and VSC light on. What does this mean?


Many possibles, but first check gas cap for torn gasket or just being loose. The VSC light is related to emissions issue and can be leaking vac hose, bad purge valve and other such.

2005 Toyota Highlander check engine, track off and vsc light on, what is the problem


there are literally hundreds of codes that would turn on the check engine light. the track off and vsc lights come on together, indicating a problem with the traction control system. again, many different items will turn these lights on. the only way to narrow it down is to hook it up to an OBD-II diagnostic tool and find out all the codes that are listed. if you don't have one, take it to a shop

VSC and check engine light are on (toyota highlander 2003). Replaced gas cap (leaky seal). Is there a way to reset the warning lights?


you can remove the negative battery terminal for 10 minutes. this will also reset all your adaptive memory. aka the stuff the car learns about your driving habits so if you do this its going to drive a little funny for a bit but it will go back to normal. hope that helps
