Diagnosing Activated PSM Warning Light in Instrument Cluster
The performance piston business today is hot thanks to a strong racing market and the introduction of new OEM engine families such as Chevy’s LS1/LS6 V8s, Ford’s 4.6/5.4L V8s and Chrysler’s Hemi. Piston manufacturers are introducing new performance pistons for all of these applications as well as refining existing piston...
Although better materials and manufacturing technology have extended the timing belt replacement intervals on many nameplates, timing belt replacements remain one of the most profitable scheduled maintenance services. They continue to be profitable because many other scheduled services like spark plug replacements, filter replacements, coolant changes and transmission fluid changes...
“CAN” is the new buzz word in automobile diagnostics. It stands for Controller Area Network and is a protocol for onboard diagnostics and scan tools. CAN is a high-speed data link that provides more information at a faster rate for better communication between onboard electronics and external diagnostic equipment. Many...
Some 2000-2002 Hyundai Accents with 1.5L SOHC and 1.6L DOHC engines may experience the following symptoms in hot and humid weather: Slower than usual acceleration after an initial cold start (engine is cold soaked). Greater than usual rpm drop when engaging drive or reverse (on ATM-equipped vehicles) after an initial...
It takes a lot of amps to power the lights, electric defrosters, wipers, power windows, power seats, power liftgates, the ignition system, fuel injectors, fuel pump, cooling fan, A/C compressor, heater fan, heated seats, audio system and navigation systems on today’s late-model vehicles. Since alternators can generate only so many...
What Was Wrong with a Cable? As if a simple cable linking the gas pedal to the throttle plate wasn’t good enough, engineers have now made that design complicated too. Why do engineers do these things to us? That expensive throttle body can’t cost less than a cheap little throttle...
Here in the upper part of the West Coast, four-wheeling is a very large part of outdoor recreation. Vehicles of all kinds are taken to the forests and mountains every weekend. There are miles and miles of off-road trails, and organized clubs are available for every make, model and size...
Most of us remember the “good old days” when an engine’s air/fuel (a/f) ratio was controlled by a mechanically operated carburetor. Due to the inherent design limitations of mechanical systems, however, carburetors don’t respond efficiently to changes in barometric pressure, temperature and humidity. In the quest for improved fuel economy...
A mere 0.7 of a mile does not sound like much, it is about 3,700 feet, or less than one-third the distance around Daytona International Speedway. On average, the U.S. population of vehicles will get 20 miles per gallon (including light trucks and passenger vehicles). A 0.7 of a mile...
