4x4Wire Tech Hint: "Check Engine" Light

"Check Engine" Light

Vehicles manufactured since 1974 began sporting a variety of engine and emission control systems.  As the engine control and monitoring systems became more complex, on-board diagnostic systems were developed to record fault codes and assist in problem diagnosis.

In general, all vehicles equipped with on-board diagnostic systems (OBD-II is the current standard) will store error codes that can be read using a portable code reader or scanner.  A "Check Engine" light comes on to indicate that the engine management computer has detected a problem related to emissions or engine operation.  It is your notice that something needs to be fixed in order to comply with federal emissions requirements or to keep your engine running.

Many of the trouble codes relate to engine or emission sensor inputs that have failed or are out of tolerance.  The sensors control the "engine management computer" and keep the engine running at optimum efficiency.  Failed or out of tolerance sensors mean your engine is not operating at optimum efficiency.

While it is easier to read the fault codes with a code reader/scanner, most vehicles provide an option to display the codes without a scanner.  

To view the error codes, start with the engine turned off (Ignition Key in the OFF position).  Turn the ignition key to the "ON" (not "IGNITION/START") position, then turn it off for about a second.  Turn it on for a second, then turn it off for a second.  The third time you turn it on, trouble codes should begin flashing on the odometer display.  (NOTE: this process works with newer Jeep vehicles.  It may or may not work with out models.)

Once the error codes are recorded, interpretation will indicate the likely source of the fault.

With Summer Driving Increasing, Goodyear Has Key Tire Advice

AKRON, Ohio, May 20 /PRNewswire-FirstCall/ -- Although miles driven have been declining in the past year, the nation's most well-known automotive travel authority predicts a higher number of drivers during this Memorial Day holiday weekend.

And the best-known American tire company predicts that many of those travelers will simply jump into their vehicles and drive, unaware of the condition of the only part of their cars that comes in contact with the road - the tires.

Officials from The Goodyear Tire & Rubber Company urge motorists to take a few minutes to inspect their tires, or to visit a local tire and service outlet for a check-up. This advice comes at the outset of the holiday weekend in which AAA (American Automobile Association) estimates that larger numbers of Americans - 32.4 million, versus 31.9 million a year ago - will travel 50 miles or more from home. This represents a 1.5 percent increase from last year.

AAA says 83 percent of those holiday travelers are expected to go by car, truck or van. With Memorial Day considered the beginning of the summer travel season, this rise in expected driving is accompanied by gas prices that are averaging about 28 cents per gallon more this week, as compared to average pump prices just a month ago.

According to Goodyear, an increase in the price of gas is even more incentive to check tire condition and air pressure before heading off on any vacation journeys.
