SOURCE: toyota Rav4 D4D 2006,warning lights check

okay.how would the injectors have anything to do with the vehicle stability control/4wd.??if it were injectors at such a low mileage you would feel a real lack of power.now as toyota own diahatsu you could save yourself a fortune if you ask them to diagnose a fault!!to check vsc is working put car in 2nd and floor the pedal turning as tight a circle you can brave.it should stop the inside wheels from screaming....to check 4wd do the same and you will feel the car trying to pull itself apart.you will see what i mean.!!!

SOURCE: code P0A93 for toyota PRIUS WHAT IS THE PROBLEM ?

P0A93 is an inverter cooling problem. The inverter is cooled by a dedicated cooling system, which consists of an electric water pump, cooling fan, and radiator. This cooling system is independent of the engine cooling system.The mechanic should check if there is sufficient amount of coolant for the inverter, check if the coolant hose is not bent or clogged, if the water pump / cooling fan motor connections are ok, and of course if both of the cooling fan motors are OK

SOURCE: My check engine light and

your O2 sensor heater circuit is not working. Can be caused by wiring, including connector, or sensor. Check connector. If good, it's probably the sensor. You can troubleshoot the sensor if you have an ohmmeter. If you want to do this, please get back to me and I'll send instructions.
The sensor is screwed into the exhaust manifold on the front of the engine.

2007. Why did check engine light and VSC message come on?

Your VSC system doesn't have anything to do with your gas cap, unfortunately. You're going to either need an OBD2 Scanner to read the messages for your check engine light or take it to a mechanic/dealership to read the code and reset that light. You can also go to Autozone if memory serves and borrow a scanner to see the codes. You can pick up scanners from amazon for 10-50 USD, or about 40 USD from Autozone. Your VSC system not working means that you're not going to have optimal stability while driving until you can get the system operational again. Note that since it's Toyota Proprietary, you will not be able to read the VSC codes with the scanner, just the standard check engine codes. If your vehicle's braking system still seems to work, it could be a sensor malfunction, but I would recommend you take your vehicle to a Toyota dealership (unfortunately) to see if they can find the fault. Don't let them BS you either... http://www.greenhybrid.com/forums/f49/check-vsc-system-warning-dealer-says-normal-display-20826/index2.html

2005 Toyota Prius. Red Brake and yellow ABS and VSC warnings are continuously on.Dealer told me to replace 12 volt battery power supply. Done that but no resolve.Anything I else I can check??

One or more ABS sensors or ride-height sensors could be bad. You need specialized dealer-only scanner to read codes to determine actual problem if new 12 volt battery didn't solve it.

Click sound when shifting gear and parking

The clicking noise could be related to the bigger problem with the abs/vsc actuator, this is a kind of common problem on the prius models, the actuator should be replaced, this is a very expensive part (around $2000) for the part only, while the warning light is on the traction control and abs are disabled, it will still brake normally.

2001 toyota avalon engine and vsc light stays on

You have to use a scanner and pull the code out that is causing the check engine light to come on. whatever code/codes you find are probably related to vsc light.
Good luck and keep me posted

Warning lights

On a Prius, when the check engine light comes on it indicates a malfunction in the powertrain control system. You need to have the car scanned for codes to see where the fault lies. The red triangle lights because the check engine light is on. The VSC is disabled when the check engine light is on and that light comes on.
Start with having the car scanned.
