How Sensors Provide ‘Good Input’ for Diagnostics
One of the systems that Subaru has perfected through improved reliability over the years has been its distributorless ignition system (DIS) for all of its models. Because of the horizontally opposed design of its engines, the ignition system can be centrally mounted and made simple. In this article, we will touch on some common diagnostic
GM Timing Belt & Chain Service
Some overhead cam engines in General Motors vehicles use timing belts to drive the cam (the 2.0L for example), some use chains (2.3L Quad Four, Cadillac’s Northstar dual overhead cam 4.6L V8, the Aurora Northstar 4.0L V8 and Chevy’s Vortec 4200 inline six), and some use a combination of both (Chevrolet’s 3.4L V6).

Diagnostic Dilemmas: Playing the Diagnostic Shell Game
More often than not, deciphering diagnostic trouble codes is like playing a high-tech version of the old circus sideshow “shell” game. In the trouble code shell game, we are led to believe that the pea (diagnostic solution) is hidden under one of the shells (DTCs) stored in the diagnostic memory. Unfortunately for the diagnostic technician,
The Fuel Injector Market and System Configurations
Looking back into automotive history, it’s hard to believe that carburetors were still being installed on import vehicles as late as 1989! But carburetors require all sorts of external vacuum and electronic gimmickry to control the cold-starting, fast idle, hot idle and low-speed cruise functions. Electronic fuel injection has since replaced carburetors in all import

When you talk about performance cars, a list of several manufacturers comes to mind. Before the explosion of Asian-made mini rockets, you needed to go European, and specifically German, to get the latest in performance machines. BMW has been the performance marque of choice for several decades. While BMW makes it difficult to improve on
Underhood Service: Troubleshooting Troublesome Injectors
Clean fuel injectors are a must for peak engine performance, fuel economy and emissions. If the injectors are dirty and can’t deliver their normal dose of fuel, then performance, fuel economy and emissions are all going to suffer. Dirty injectors can’t flow as much fuel as clean ones, nor can they deliver the correct spray
Nissan Engine Diagnostics
You don’t have to be an import specialist to know that Nissan cars and trucks have a good reputation for reliability and longevity. Nissan, under the Datsun name, was one of the first Japanese automakers to break into the U.S. market. They did it right, by establishing a strong dealer network and offering a quality
Ford Timing Belts & Chains
Timing belt and chain replacement is one service that isn’t going away any time soon. Most Ford engines with overhead cam timing belts have a recommended replacement interval of 60,000 miles to 120,000 miles depending on the application (see the chart on page 54). So if a customer is driving a vehicle that is more
Diagnostic Dilemmas: Driving Forces Behind a Driveability Technician
He used to be known as the tune-up guy, the shop troubleshooter or the ace mechanic. Today, he’s known as a driveability tech. Tomorrow, when body control electronics come on full line, he’ll probably be known as an electronics diagnostics technician. Whatever his name might be, most of us know that driveability techs are smart,
