How Long After Ob2 Codes Are Cleared Before the Check.in Again
Neither black tape nor a magic marker is the solution when your car or truck'south cheque-engine lite comes on. When the calorie-free, which is shaped like the outline of an engine, illuminates, practice non panic! And definitely practise not attempt to comprehend up the warning. There'south a much meliorate way to deal with the trouble. Here'due south how.
For starters, information technology's important to know what the dashboard lite is actually telling y'all. In some vehicles, there are separate alarm lights labeled Service Engine or Maintenance Due, versus a more traditional Cheque Engine light. If at that place'southward whatever confusion well-nigh which calorie-free you're looking at, check your possessor's manual.
If it's a maintenance-related warning light, then you can relax, at least temporarily. This type of light is your machine telling you lot that some routine piece of work is due, such as an oil or air-filter change. Imagine if your teeth started glowing every six months when a cleaning is due. Granted, you'd look a petty funny, but information technology wouldn't mean a root canal was automatically on the agenda.
What a Check-Engine Low-cal Means
If you're positive that it's a bank check-engine alert lite staring back at y'all from the gauge cluster, there are some key things to remember.
- If the lite is a steady orange or yellowish and there is no perceptible change in how the car is driving, you lot don't demand to finish the vehicle immediately. There is a good chance it could be a minor trouble, but, as we've already noted, it'due south non smart to ignore the problem until the car does have noticeable issues. Sometimes, something as simple as a loose gas cap tin be the culprit.
- In the rare instance that the warning lite starts flashing, however, pull over and stop the motorcar. This almost always indicates a serious trouble has occurred, and severe harm could be done by continuing to drive the automobile.
Assuming your musical instrument cluster is showing the more common solid amber or yellowish check-engine alarm, there's an easy-to-use tool that tin can help you empathise what's going on long before y'all visit a repair shop or dealership. That'due south because every car built from the 1996 model twelvemonth onward speaks the same basic language—and deciphering it takes far less time and coin than you'd imagine.
Connecting to an OBD-Ii Port
You can discover out what's ailing your engine through the vehicle'due south OBD-2 port. An OBD-II port might sound like something R2-D2 would fall in dearest with and marry, but in reality it's a simple diagnostic connectedness establish on every postal service-1996 automobile and truck. Yous plug an OBD-II scanner tool into it and, in most cases, out pops a code that tells y'all what the trouble is. The scanner also allows you to articulate the vehicle'due south internal code, which is what triggered the bank check-engine lite. Do that, and the alarm lite will turn off.
More on that later. To close off the alert light, and to know exactly what's incorrect with your vehicle, yous need a scanner. While a professional-form OBD-II (also known as an OBD2) scanner might price you lot hundreds of dollars, a wide range of perfectly good consumer models can be found online from betwixt $20 and $100. Some are wireless; all plug into the OBD-Two port. Past communicating with your phone, tablet, or laptop, the wireless units access an app that provides the diagnostic information that could indicate the trouble with your car or truck. Some of these wireless scanners include the app in the purchase price and some do non. Do your homework, since non every app works with all types of wireless devices. (The two scanners shown here are ones we take had good experiences with in the Car and Driver test garage. Several staffers likewise written report that they own depression-priced wireless scanners that work extremely well.)

Once you've acquired your preferred scanner, using it is easy, and information technology won't leave y'all covered in engine oil. Meliorate however, it could potentially salvage you lots of money. Hither's how information technology works:
- First, locate your car's OBD-II port and plug in the scanner, or the adapter that will link to a wireless device. Make certain your auto is then turned on and running so the scanning software can begin. In that location might be some basic prompts that ask for additional information such equally the make and model. If y'all need your auto'due south Vehicle Identification Number (VIN), you'll usually detect it on a metal tag at the base of operations of the commuter's side of the windshield (information technology'south often easiest viewed from exterior the vehicle).
- Depending on the scanning device, it shouldn't take long for any potential trouble codes to announced. When an issue surfaces regarding how your car is operating, the vehicle's onboard calculator records information technology as a standardized code. Thanks to OBD-II technology, all cars have the same basic codes.
- Your scanning device might immediately trace where the problem can be constitute. More advanced scanners (usually more complex and expensive models) will have a wider range of capabilities, so go on this in mind if you plan to use the scanner regularly.
- When the diagnostic code appears, information technology will too provide basic data about what'southward causing the issue. This can be helpful if yous're taking your car to a dealer or independent shop for repair. If your repair estimate comes dorsum with a completely different issue, information technology might bespeak that something fishy is going on.
However, some discrepancies might arise between the codes you read on your scanner and what a dealership or shop uncovers, then don't automatically assume you lot're beingness conned. Given the complication of today'due south cars and trucks, the more advanced tools used at a repair store can sometimes uncover additional issues. Call back, ask plenty of questions and stay informed, especially when the codes announced dissimilar.
If your main reason for buying an cheap scanner is to reset the bank check-engine light, know this: clearing the code and turning the light off doesn't mean your result has gone away. Some check-engine light warnings are temporary—like the aforementioned loose fuel-filler cap or a rare engine misfire. It's possible that the warning lite won't come back on later you clear the code.
Then again, if the light does come on again presently, y'all must conclude that yous practice take an issue that needs to be addressed. And if you can't handle the repair yourself, and so you should take it to a shop and have information technology attended to. Failure to do so could price you a lot more than later.
And so put away that black record and magic marker, and take time to sympathize what your car is telling you when the check-engine alert low-cal turns on. After all, if you can plug in a smartphone and punch in an Amazon lodge ID, yous have all the skills needed to install an OBD-Two sensor and read a elementary lawmaking regarding what'south ailing your car.
