How Your Check Engine Light Works
Posted April 30, 2010 1:00 PM
Have you ever had an experience like this in Bloomington, Indiana ? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your Check Engine light starts flashing!
You fear the worst, but within a block or two, the light stops flashing, but stays on. By the next day, the light is off.
You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works.
Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage.
Warning, warning! It flashes the Check Engine light to alert you to take immediate action.
It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine control computer says the danger is past, but I'm still concerned, I'll keep this light on for now.
Then the Check Engine light goes off in a day or two.
The condition never did recur, so the computer says whatever it was, it's gone now. The danger is past, I'll turn that light off.
Now a flashing Check Engine light is serious. You need to get it into AutoChoice Service Center Inc. as soon as possible. But if it stops flashing you can wait a few days, so you have time to see if the problem will clear itself or if you need to get it checked. How does the computer know when to clear itself?
Think of it this way. The engine control computer is the brain that can make adjustments to manage the engine. Things like alter the air-to- fuel mix, spark advance and so on. The computer relies on a series of sensors to get the information it needs to make decisions on what to do.
The computer knows what readings are in a normal range for various conditions. Get out of range, and it logs a trouble code and lights up the Check Engine warning.
The computer will then try to make adjustments if it can. If the computer can't compensate for the problem, the Check Engine light stays on.
The computer logs a trouble code. Some people think the code will tell the technician exactly what's wrong.
Actually, the code will tell the technician what sensor reading is out of parameters. It can't really tell him why, because there could be any number of causes.
Let's say you're feeling hot. You get your heat sensor out – a thermometer – put it under our tongue and in a minute or two you learn that you have a fever of 104 degrees F (40 degrees C).
You know your symptom – a fever – but you don't know what's causing it. Is it the flu, a sinus infection or appendicitis?
You need more information than just that one sensor reading. But it does give you a place to start and narrows down the possible problems.
There are reports on the internet telling you that you can just go down to an auto parts store and get them to read your trouble code or buy a cheap scan tool to do it yourself.
There are two problems with that. First, the computer stores some trouble codes in short term memory and some in permanent memory. Each manufacturer's computer stores generic trouble codes, but they also store codes that are specific to their brand.
A cheap, generic scan tool, like you can buy online or that the auto parts store uses, doesn't have the ability to retrieve long-term storage or manufacturer specific codes. Your Bloomington, Indiana , service center has spent a lot of money on high-end scan tools and software to do a deep retrieval of information from your engine control computer.
The second problem is that once you've got the information, do you know what to do with it? For example, a very common trouble code comes up when the reading on the oxygen sensor is out of whack.
So the common solution is for the auto parts store to sell you a new oxygen sensor — which is not cheap — and send you off on your way. Now your oxygen sensor may indeed have been bad and needed replacing. But the error code could have come from any of a dozen of other problems.
How do you know the right solution? Back to the fever analogy, do you need surgery or an aspirin? Leave it to the pros at AutoChoice Service Center Inc.. Give us a call and let us help you resolve your check engine light issue.

Are There Blind Spots in Bloomington?
Posted April 22, 2010 1:00 PM
All Bloomington drivers have blind spots – and no, I'm not talking about the fact that you really don't sing like Adele. I mean the areas of the road that you can't see when you're driving around Bloomington.
First let's talk about our own blinds spots, and then we can talk about others...
To begin, we can greatly reduce blind spots by properly adjusting our mirrors to give the widest coverage possible. Make the adjustments in your vehicle before you start to drive.
First, Bloomington drivers should adjust their rear view mirrors to give the best possible view directly to the rear of their vehicle. Bloomington folks don't need it to get a better view of either side of the car, the kids in the back seat or their dazzling smile. It's pretty obvious, the rear view mirror should reflect the rear.
Next, lean your head until it almost touches the driver's side window. Adjust your side mirror so that you can just barely see the side of your car. Now, lean your head to the middle of the car and adjust the outside mirror so that you can barely see the right side of the car.
When Bloomington drivers adjust their mirrors this way, they'll have maximum coverage. Of course driving is a dynamic process – things change every second on Indiana roads and busy highways. So it's wise to take a quick look to the side when passing to make sure that another vehicle hasn't moved into an area you couldn't see in your mirrors.
As you drive around the Bloomington area, avoid staying in others' blind spots. You can't count on them to be watching their mirrors and looking out for you.
Here are some tips for passing a heavy vehicle on Indiana roads:
Avoid the blind spots. If you can't see the drivers face in one of his mirrors or in a window, he cannot see you!
Don't follow too close. If you can't see one of the truck's mirrors, you're too close.
Make sure there is plenty of room to pass. Trucks are long and take time to get around. If you're on one of our local two-lane highways, wait for a passing zone.
Don't linger when passing. Because the blind spots are so big on the sides, you want to get through them quickly. If you can't pass quickly, drop back.
Pass on the left whenever possible. A trucks' blind spot is much larger on the right.
The team of automotive professionals at AutoChoice Service Center Inc. want you to watch those blind spots – but feel free to sing in the shower all you want.

ICE - In Case Of Emergency In Bloomington Indiana
Posted April 8, 2010 11:00 AM
When accidents occur in Bloomington, Indiana , the victims' emergency contacts are extremely important. Too often, those involved aren't able to provide rescuers with phone numbers and medical information.
When Indiana police and rescue workers must sift through pockets, glove compartments, wallets, purses and cell phone directories, they waste precious time.
In the unfortunate event that you are involved in an accident, you have people in the Bloomington, Indiana , area who you'll want to be contacted to arrange help, give consent to treatment and inform Bloomington paramedics of medical conditions, allergies or medications.
A brilliantly simple solution is now spreading through Bloomington and around the globe: ICE. ICE – standing for In Case of Emergency – is a way to identify emergency contacts in your cell phone directory.
Simply put 'ICE' before a contact name in your cell phone, like 'ICE – Dad,' 'ICE – Nancy.' or 'ICE – Doctor Roberts.' Rescuers will be able to quickly identify your emergency contacts, saving valuable time.
Bob Brotchie, a Cambridge, England, paramedic came up with the idea and a promotional campaign in England in 2005. This idea is gaining attention in Bloomington, Indiana , and in other countries. Bloomington rescue workers all know of how many times they are unable to find a wallet or purse on an accident victim, yet most Bloomington area folks over 14 years of age are seldom without their cell phone.
There are national and worldwide disaster databases, but participation can cost up to $200 a year. 'ICE' is free to the 276 million cell phone users in the U.S.
It is easy for you and your families to designate some ICE contacts in your cell phone. Remember to keep the listings current.
Please join AutoChoice Service Center Inc. in getting the word out. Help us put Bloomington, Indiana , on ICE!

Which Item Is Most Stolen from Vehicles in Bloomington?
Posted April 2, 2010 10:00 AM
Which item is most often stolen from vehicles in Bloomington?
Is it:
- Stereo
- Wheels
- Air Bag
- DVD System
Well, if you said stereo – you used to be right. But airbags have now surpassed stereos as the biggest target for theft in Indiana – approximately 50,000 a year are stolen across the country. New airbags cost about $1,000, but go for $50 to $200 on the black market in Indiana .
Stolen airbags are making their way back into cars that have been in an accident. Of course, the danger to the consumer of having a stolen airbag installed is that you can never be sure what may have previously affected them and if they will work right when you need them.
Contact us at AutoChoice Service Center Inc. for more information about where to get your airbags checked or replaced.

There are reports that 1 in 25 airbag replacements are stolen or salvaged airbags – or no airbag is installed at all.
That is definitely one car part you don't want to take a chance with, so AutoChoice Service Center Inc. recommends following these guidelines:
- Use a reputable collision repair center that employs ASE certified mechanics (we can offer recommendations at AutoChoice Service Center Inc.).
- Inspect the invoice to ensure that the repair shop purchased the airbag from a manufacturer, dealer or recycler. If you can inspect the airbag prior to installation, it should be packaged in a sealed container from the manufacturer.
- You will see the SRS light (Supplemental Restraint System) when you first start your vehicle up. This tells you that the airbag system is activated. If you do not see the SRS light, there is likely a problem with the airbag system.
