Important Understanding of the Engine Light Functions

Your auto's Check Engine Light, or sometimes referred to as the Malfunction Indicator Lamp (MIL), is associated wtih modern day computerized engines and can be an indicator of something needed attention in the computerized engine management system. They are often and commonly referred to as 'Trouble Codes'. When illuminated, it is typically either an amber or red color. On vehicles equipped with OBD-II, the light has two stages: steady (indicating a minor fault such as a loose gas cap or failing oxygen sensor) and flashing indicating a severe fault, that could potentially damage the catalytic converter if left uncorrected for an extended period.

In some makes and models, the code diagnosis maybe retrieved without a scan tool, but every make and model is different. The malfunction indicator lamp usually is stated as check engine, service engine soon, or in a few instances an Icon of an engine. Currently, in the United States, specific functions are required of the MIL by EPA regulations.

The MIL first appeared in the early 80s along with computerized engine controls. On cars older than 1980, there was no such indicator but instead had a single indicator labeled "trouble" or "engine"; this was not a MIL, but what was often referred to as an "idiot light" meant to indicate possible serious trouble with the engine (low oil pressure, overheating, or charging system problems) and an imminent breakdown. Initially these lights were designed to go off, or illuminate, at the beginning of a problem instead of after serious problems went on too long.

The "idiot light" terminology arises from popular frustration with automakers' use of tell-tales for crucial functions which could previously be monitored by gauges, so a troublesome condition could be detected and corrected in the early stages, not after the fact. Such early detection of problems with, for example, engine temperature or oil pressure or charging system operation is not possible via a tell-tale, which usually illuminates only once a fault has already occurred – thus providing no advance warnings or details of the malfunction's extent.

Even the most uneducated individual can quickly learn the proper levels their car should be reading thereby giving the opportunity to correct a problem before it worsened, a simple engine light, does not provide for such any early detection.
An auto well equipped with Gauges goes a long way to help see a potential problem before it gets to that point. That is one reason why many of those with High Performance autos have a full array of actual 'read-out gauges' that actually provide the levels for each function in real time. This usage of the "engine" light was discontinued in the mid-1980s, to prevent confusion with the MIL. The MIL is commonly referred to today as the "check engine light" or the "service engine soon light", however, many cars today have both. Usually in this case the Service Engine light is more of a servicing notice, for example time to change your oil.

On-board diagnostics (OBD) is an automotive term referring to a vehicle's self-diagnostic and reporting capability.

OBD systems give the vehicle owner or repair technician access to the status of the various vehicle subsystems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1980s versions of on-board vehicle computers. Early versions of OBD would simply illuminate a malfunction indicator light or "idiot light" if a problem was detected, but would not provide any information as to the nature of the problem. Modern OBD implementations such as All Car Specialists untilze, use a standardized digital communications port to provide real-time data in addition to a standardized series of diagnostic trouble codes, or DTCs points the technician in the direction of the malfunction within the vehicle. Look at it like a Compass in the desert, it will give you a basic direction of the best way to head.

OBD-II diagnostic check
OBD-II provides access to information from the engine control unit (ECU) and offers a valuable source to assist with troubleshooting problems inside a vehicle.

You must understand that good Damage Control efforts can prevent a lot of needless expense.


While the actual schedule of car maintenance varies depending on the year, make, and model of a car, van, suv or truck, as well as its driving conditions and driver behavior, Maintenance can prevent a lot of expense in mechanical repairs later on. Early and Regular Maintenance cannont be overstated to protect both your Automobile and your Pocket Book.

Here is a helpful and valuable Check List to go by such as:

- Number of trips and distance traveled per trip per day
- Extreme hot or cold climate conditions
- Terrain, example: mountainous, dusty or de-iced roads
- Heavy stop-and-go vs. long-distance cruising
- Towing a trailer or other heavy load

Just remember, constant use on any of the above not only places extra stress on the engine but on your entire Drive Train and Transmission. You can watch one of Paul's Videos on Transmission Maintenance for futher tips right in the video in the first column.

Hot Temperatures can affect the Entire Auto's Operating system. Most people just think that if the engine overheats then only the engine was affected. This is entirely Wrong. If you have an automatic transmission it has a coolant line going from the Radiator to the Transmission that cools the Tranmsission Fluid to keep it running sound and strong.

Experienced service advisors in dealerships and independent shops recommend schedule intervals, which are often in between the ideal or extreme service schedule and for good reason. They base it on the driving conditions and behavior of the car owner or driver. Sure, you may say, of course they do, they just want your money for extra business. Well there may be some shops that will tell you that your car is in need of numerous maintenance items, but not All Car Specialists. When you come into All Car Paul Brow will only tell you what he finds is actually in need of maintenance and make suggestions ONLY on his findings, not on a potential bill he can right up for you. All Car has a reputation of word of mouth or referral busines and it has been earned by honesty, integrity and reliability for 4 decades.
