What Is the objective of the "Service Engine Soon" irradiate on your Dash?

The initial impact of seeing this little light on her dash is to scare the living gezebbes out of you. Immediately, you assume the worse and also fear that you should spend hundreds or hundreds of dollars to "fix" her car.

The intended function of the "service engine soon" light is to warn the operator of the vehicle that a breakdown has been detected by sensors in the emissions device of the vehicle. There may be a major problem with the engine or one of its components, but it's generally a boy issue.


First, examine Your Gas Cap

The culprit could be as simple as having actually a loose or faulty gas cap. Before you drop hundreds of dollars at the garage, tighten the gas cap, make sure your gas tank is much more than fifty percent full, and then drive for about fifty percent an hour. If the irradiate does not go off, shot buying and installing a new gas cap. They cost less than $10 at her local car parts retailer. The is worth judgment out this usual problem prior to proceeding to bring in the car for an expensive organization call.

It Wasn't the Gas Cap?

Uh-oh!

Well, i know people who phone call me the their light has been on for the last 5 years! ns personally wouldn't walk that long without law something about it. If the light is top top solid, you most likely have actually an emissions issue, no necessarily urgent, yet one it would be wise not to avoid. If the irradiate is blinking, you have actually an urgent issue and also must go instantly to a garage.


The problem could also be something like the oxygen sensor, i beg your pardon monitors how much unburned oxygen is gift released v the exhaust. Not an altering the oxygen sensor timeless may reason damage to your catalytic converter, a component that could cost as much as $2000, while an oxygen sensor may cost from $20 come $120 depending upon your vehicle. If you room "handy" it might be feasible for you to change the oxygen sensor yourself. The procedure is usually detailed in your owner's manual; the is usually as straightforward as removed the old sensor and also popping the brand-new one in. Doing it you yourself will cost you much much less than going to a garage.


Other problems might be a dirty or defective MAF (Mass waiting Flow) sensor). A possible cause of a dirty or defective MAF sensor is failing to change your air filter, or installing the air filter improperly. You can shot to purchase a deserve to of MAF sensor cleaner because that $10, however a word of caution as these sensors are very fragile. A new sensor deserve to cost between $75 and $200, depending upon your vehicle model, and is basic to install.

Another feasible culprit triggering the "service engine soon" irradiate is misfiring spark plugs. Spark plugs on older vehicles (before 1996) necessary to be readjusted every 40,000 come 50,000 kilometers; ~ above more modern-day vehicles spark plugs have the right to go to 150,000 km prior to needing to it is in changed. Faulty spark plugs can reason your engine to misfire. If you feel her engine falter occasionally, or the engine has actually a jolty feeling under acceleration, your engine is misfiring and throwing off your fuel efficiency.


So how do you recognize for certain whether it's spark plugs, MAF sensor, or miscellaneous else?

Get an OBD II Scanner

You've ruled the end the simple, typical causes and also your irradiate is still on. You now have actually two choices:

Bite the bullet and bring the automobile to the mechanic. You auto will it is in fixed and also your mechanic's youngsters will have actually a nice Christmas.Or, you deserve to at the very least do some of the investigative work yourself by getting a code-scanning device.

A code scanner or OBD II (On board Diagnostics II) scanner varieties from $10 top top eBay to $200+ because that a really great one at your regional auto parts store. The savings can be remarkable after a couple of "service engine soon" light incidents. The initial price of a mechanic's visit will begin at $100 simply to acquire the error password from her car's onboard computer. Add a pair hundred because that labour and also inflated costs for parts, and your mechanic is happy to check out you every time.


Or you have the right to spend money when on the OBD II password reader, acquire the actual low under on what is happening because that yourself, discover your own parts, and also save a bundle. The cost of the OBD II password reader will cover itself with every error irradiate incident. That can additionally be provided on number of cars come maximize savings.

If you room not comfortable v the installation of details parts, you can do your very own diagnostics, buy the components yourself, and also leave the installation come the mechanic; you will certainly still save at the very least 50% the what it would certainly have cost if you left it all to the mechanic.

I have a 2004 maxima. I want to collection it on fire. I had actually transmission problems, but will keep quiet around it lest ns jinx myself. Anyway, trouble is the examine engine light. The password coming up space for oxygen sensors. I've had them all replaced with some running end %100 and the irradiate still comes on, very same codes. Mechanics had it four times, said me to take it come the dealer. Dealer had it around 8 times, actually wiped the computer and reprogrammed it from scratch, irradiate still came on, very same codes. It's been virtually 2 yrs now, the longest it continued to be off was a week when they delete everything the computer. I had them do a "hard reset" to acquire the emissions done and the light stayed off for 200kms. Yes truthfully, I've had actually the irradiate shut off and come earlier on so numerous times the I recognize it comes ago on in 211kms exactly, sad i know. The dealer couldn't figure it out so they came up with a story about having an after sector exhaust, and it 1/16th of one inch smaller so it's reading it wrong...blah, blah, blah...you require a new exhaust because that $2500.00, also thought mine to be 6 months old in ~ the time. The males that go the emissions stated the codes had actually nothing to carry out with the exhaust, it's around the mixture, it's running also lean or something. At this point I feel favor taking a screw driver and poking the f**king light out myself. Mine gas cap is fine, you deserve to hear the push release as soon as you open up it therefore I know its working. I've had actually so numerous problems through this car, the blows headlights at the drop of a hat, in ~ $100.00 a bulb thats a pain. In ~ this suggest if I deserve to just gain the cursed engine light to stay off, i may take into consideration not setting said auto on fire.

No must spend money on OBD scanner, just watch this youtube and also check out the sensor issue yourself. Https://www.youtube.com/watch?v=jvWE71-kH6U

Once girlfriend pump her gas in this manner, your light will begin to blink. Count each blink and also you'll get the organization code #, then examine what the net says is the cause. You have the right to reset the business light yourself and it turns off. If the light comes ago on ideal away climate there's one issue, if not maybe just a fluke. My engine light came on and also I didn't want to spend the money to figure it out, without reason, so ns investigated the myself and also reset it. Critical 7 months vehicle ran fine through no issues. Light simply came on again this evening with exact same code. I repetitive the steps and light's off now. Mechanic said automobile has no issue. Mine is a 2004 Nissan Sentra, perhaps its simply showing its age.

This is precisely what occurred to me last October. I have a 2006 Toyota Scion XB. The dash lamp lit up irradiate a Christmas tree. What did it mean? I was in a full panic and also had visions that a fix costing thousands of dollars. Took it come an AutoZone store and the employee ran the diagnostic because that free.

Ardot (author) native Canada on December 16, 2014:

Hi Andy, thanks for liking my artilce, yes it bring away a while for the irradiate to go on, as well as off. Through the gas cap scenario, ns think it has to do v the pressure in the tank, when the cap is loose, the press drops and triggers a sensor that there's one emissions problem.

I looked at the write-up you pointed out as gift similar, I discovered it to be very brief in comparison come mine. We carry out share few of the exact same terminology, yet it's all common knowledge.

At that point the light will go out, if it's the cap.
