LexusPro : Hello and welcome to JustAnswer! I'm reviewing your question and will be with you in just a second.
LexusPro : You most likely have a sensor that has malfuctioned. Most auto part stores will check it for codes for free. When you get the codes I can give you a better idea of what to check next.

Thanks. I'll check with AutoZone. Thanks

LexusPro :

Let me know what you find. If I had to guess I would say a bad wheel speed sensor.

JACUSTOMER-dcijn3dt- :

I will let you know what the code is. Thanks.

LexusPro,

Thanks for your help. The VSC (Vehicle Stability Control), light now operates with the switch as normal. The technician at AutoZone told me to give the MAF Sensor time to reset. So I...

1. Let the car run for approximately 20 minutes then turned the engine off.

2. Turned the ignition switch to auxiliary and plugged up the Code Reader.

3. Erased the existing codes.

4. No codes remain.

5. Car operates PERFECTLY NOW!

 

Thank you for your help. So I guess to end the session, I must state that , "I do not accept the Answer"?? thank you.

LexuePro,

I've noticed that there is still a request to "Accept Answer". Thank you for your guess of "Wheel Speed Sensor" but the "Mass Air Flow Sensor" was the solution. The missing step was to let the MAF "Reset" or "Sync" with the automobile. After an idle of 20 minutes the car's idle returned to normal and the rough running ended. If there is a requirement for you to release the $18.00 please do so. Thank you for your communication. I hope to communicate with you in the future.

I will send your request to site staff. All that had to be done after replacing the sensor was to clear the codes(what you would do after replacing any sensor). I have never heard of a "sync" or a reset other than clearing the stored codes. If you have any other questions at any time feel free to ask. I will be glad to help.

Have you had it rechecked for codes?
Customer: replied 6 years ago.

LexusPro,

There are NO CODES.

Expert:  LexusPro replied 6 years ago.
If the light is on there are stored codes. Many aftermaket scan tools will not read body or chassis codes. You will need to have it properly checked. When you get the codes we can move forward with diagnosis.
