Help failed CA smog test due to Functional check.
I recently had my CEL turn on I had the scanner run and it said to change my O2 sensors. I did this yet it was still on I took it for a diagnostic and they told me it was my MAF so I recently changed that and my Pos battery terminal. I changed the terminal just for my own reason as it was not making a good connection. After I changed my MAF they VSC and VSC OFF remained on. I disconnected the Battery and all of the lights were gone. So I figured no problem I drove it on the Freeway and took it for the smog check. Sure enough it failed. It passed the Visual inspection and the Emissions Test. The cat passed the O2 Sensors passed everything except malfunction indicator light. The Smog check place told me to drive around more or to have it Reset.
Yet i just turned it on and now the VSC and VSC Off are on and they CEl blinks. Can someone help. I need to register my car.

yeah get the code scanned. don't know if you have autozone or advanced auto parts stores in your area but here they scan your obdII for free and give you a list of possibilities. narrow it down and take care of the issues one by one. i had similar issues with my car when i first got it as well. good luck

I did that but it only read my O2 sensors never my MAF. I changed the MAF because it was stalling out on me. It would take it awhile to change to second gear. I disconnect the MAF and they VSC and VSC OFF came on. I changed and the car drove fine but now this problem. I have GS430 01. I live in Los Angeles Area. I 'll try the scanner again though. The sad thing is I got a ticket infront of my house for expired tags. Darn....
1. get the code.
2. search on google
3. the MAF could just be dirty. If you're using a new MAF then it might be a short issue.
I cleaned my throttle body and VSC and VSC off lights both turned on. I disconnected and reconnected everything and left the battery terminal off for an hour and did the trick.

If CEL is blinking that means there is a malfunction that could cause damage to catalytic converters. Blinking CEL usually are caused by extreme rich conditions or misfire conditions. Have you recently cleaned engine compartment or exposed spark plugs to water?

You need an OBDII scanner to clear the codes. Then you need to drive around for a week or so for all the sensors to reset. This happened to me with my Cobra. I barely failed with an aftermarket X-pipe so I bought a stock one. Everything should have been fine right then and there. I took it in the next day and I failed the Functional part because all my sensors had not reset yet. I drove around for another week and took it back and then it was fine.

Hey, just wondering do you have an aftermarket intake on your car? Sounds like you're having the exact same symptoms as me when I had a piece of crap intake on mine. Car would keep stalling, CEL would blink, car would run crappy...etc.
such as any intake without an ecu add-on (aem, injen, home-made, etc..). I bought an aem intake to use the pre-welded maf sensor bung for my na-t, but i put it on my car with the cone filter before I put everything in it. Not only it threw a check engine light, but my car started to bog everywhere. I had no choice but to take off the intake.

well the light isn't blinking now just all of them stay on. The car runs fine I ran a scanner on it and no codes came up I ran the MIL and it said the light should be turned off when the car is on. Somebody please ya I knew someone who would pass it for 180. If I can just take the lights off it would be so simple. How to take these VSC VSC off and check engine light off...I'm gonna try cleaning my throttle as someone suggested. Can any one walk me through that I"m not a car genius...
