The check engine light stays on when the engine computer has detected a malfunction and set a trouble code.
cuz alot of blinks are toxic
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to a parts store or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
Pretty sure that means that the 4WD is in the process of engaging. Blinks for a few seconds then stays on. Mine sometimes blinks while in 2WD whether I'm using 4WD or not. Research on internet suggests it's fairly common problem and probably due to misaligned sensor. Since I've tested my 4WD/2WD (on ice) to see whether it was going in and out of 4WD correctly I placed window tint plastic over light so it would stop buggin' me...;) Sometimes may take a few miles of driving for it to go out. Usually after some starts and stops. Sometimes shifting into and driving in reverse a little bit does it too.
It means to physically check the gauges because one or more of them is showing you there is a problem, such as not charging, overheating, low oil pressure, etc.
you should check your engine...like now...
my check engine light stays on and the o/d light blinks....what could this mean?
get a new one
get a haynes manual at a library
Something wrong with your throttle position sensor
It means you have a malfunction in the cars engine. If it blinks stop ASAP!.. You need a scanner to pull the codes to get to what exactly is wrong
The computer does tests as you drive the car. It has found a problem in a component and is telling you about it. You will have to check for sure but it sounds like code 23 possible Air flow metering problem.
Could be anything but Check the oil dip stick. If that's ok drive to a VW garage and their sofware will give more details.
A fast flashing check engine light is an indication of a running issue that is causing severe emmisions and catalytic converter damage. The normal cause is a harsh misfire. If you have it checked for codes, it should tell you which cylinder is the problem.
An engine cylinder misfire has been detected if your check engine light is flashing
take it to the autozone they check the engine light for free
