Question about 2007 Lexus RX 350 FWD

2 Answers

My engine light, VSC and Trac off lights are on. I have almost 100,000 miles on my car and no warranty at this point. The car shakes whenever I hit certain speeds. A friend of mine hooked the computer up to my car and it said coil 1 and 2 bad. What does this mean and how do I fix this without spending a fortune at the dealership. I have a 2007 RX 350

A coil for most cars are normally not a very expensive part . Take a look on eBay for your type of vehicle for anidea if costings.
A coil is normally positioned in a placedwhichbis usually quite easy for a DIYer to fix themselves.
A Haynes manual or similar vehicle fixing manual may be worth while alternatively YouTube fixing it.

It is not hard to change the sensor, it just screws into a threaded hole. The light will not go out immeditaly, after the sensor is replaced. It needs to go thru a drive cycle. Your best bet is to replace the sensor and get the code cleard by whoever scanned it for the 0031 code.

Check your switches for the VSC, some get bumped on (due to their location) and some get stuck in the "on"position.

Vsc code c1336


That code relates to a crankshaft position sensor signal. It you have a check engine light come it disables the VSC and Trac system. Until you get that sensor fixed the VSC and the TRAC system will be inop. So whenever you have a check engine light come on that is what you will see. Even though you cancel the check engine light the fault still exists and the VSC/ TRAC light will come back on. That is a sure way to tell that something is wrong.

Hello, VSC, Trac OFF and Check Engine lights turn on when i was driving. Whats means ? In Autozone said me that problem is with the catalyst system. Thanks for your advise.


when ever the check engine light is turned on for any reason the vsc and trac light also comes on to let you know they are not working, whenever the engine light is on the other systems can not operate if the engine is not working correctly, so its programed to shut down the trac and vsc when the engine light is on. the catalyst system means the catalic converter is no longer cleaning the exhasut to specs, this is caused by a weak bad converter or bad o2 sensors giving false readings you will need to have the sensors checked to see if they are the problem or the converter is the problem good luck.

Getting message CHECK VSC with engine warning and traction lights on permanently.


Whenever the check engine light comes on it also turns on the trac and the vsc, if figures the trac and vsc can not operate properly if the engine is not running correctly, when check eng light turns off the rest will also, the first thing to do is have the computer scanned, there will be stored codes, these codes will tell you where the problem is, many auto part stores will scan it and give you the codes, if you get the codes i could help you further good luck.

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.

Why is the engine light on along with trac light and vsc light


This could be two seperate problems but the trac and vsc lights can come on when the check engine light does for a number of codes. Have the check ngine light scanned to diagnose the problem. When the problem that caused the engine light to come on is resolved and the code cleared the tra and vsc lights should turn off as well. Rarely they will stay on in which case your toyota dealer may have to do a "zero point calibration".

VSC Trac off lights on dashboard


I have just had the same problem this morning for the first time and I suspect it is just bad gas. We have had problems with the check engine light in our camaro whenever we bought hi test at the Mobile gas station closest to our home. I would not be surprised if this same gas station is now having water problems with their regular gas which is what we put in our 4runner. Try STP gas treatment first, which is what I am going to do now. When I used this approach with my camaro, the light went out within a few days. Technically, a sensor might have been damaged, but my thinking is that if that sensor is dead, then my fuel/air mixture will get bad enough to notice pretty quick. The TRAC off and VSC off are just extra lights that go on, whenever the check engine light comes on. I'll let you know how it goes.
