1999 avalon , check engine light ON, code P1155 02S

The traction control system uses the engine to slow down or speed up the car when necessary.
If the check engine light is on the traction control will not work.
You may have a problem with both systems, but having the computers scanned for trouble codes will point you in the right direction.

Toyota Avalon 2006 vsc, skid light and check engine light on. Codes P0031, P0038 and code ,P2238

if they are the same engine and vin code some things may need to be transfered over

No body can tell exept the Scan tool. Go to a close autopart store and they will scan it for you and tell you whats the code Then you will look for the Code deffinition. Good luck

charc, cansiter vsc comes on with check engine light

Hi, 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.

Take care

You need to have a code reader/scan tool hooked up to retrieve the code/s that triggered the engine light. You can have this done at most auto parts stores for free. Try Auto zone, Checkers, Napa, or Murray's. The engine light will eventually go out if the computer does not receive any codes after many cycles turning the ignition on and off. It will not go out if there are codes still present. After you've retrieve the code/s bring them back here and we will have a better understanding of what caused them.

take to a parts store that offers free code reading. that will tell you the problems

Many shops have a hand held pyrometer that can check actual engine temperature. you can get a rough idea what the temp is by using a thermometer taped to the upper radiator hose. Normal engine temp is generally in the 210degree (f) range. If it is at or close to that I'd change the temperature sending unit. If it is far below normal, check that the thermostat is not stuck open (replace if it is).

should have an OBDII connection under the dash on the drivers side. Looks like an elongated computer port, probably has a cover on it that says OBDII. You can buy a code reader from an auto store like pepboys for around $100 i think. Just a side note, usually if the car is still driving ok and not acting weird, it is an emissions sensor.
