Modern Fuel Control Diagnostics: Sorting Through the Datastream

When confronted with a fuel control problem on a modern vehicle, I’ll normally use short- and long-term fuel trims to determine if the problem is caused by one of many failures such as a vacuum leak or a leaking fuel pressure ­regulator. If you’re like me, you’ll occasionally access the air/fuel ratio (AFR) sensor serial

Toyota: Fixing Prius HID Headlamp Problems

High Intensity Discharge (HID) bulbs are unlike halogen light bulbs, which simply stop working at the end of their useful life. HID bulbs nearing their service end-of-life may flicker or intermittently be inoperable — similar to a fluorescent light bulb. Some 2006-‘09 model year Toyota Prius models may exhibit an HID headlight flicker or ­intermittent

Kia: Uncovering Unperformed Maintenance

While some vehicle problems will motivate the customer to make an appointment, an equal amount of Kia repair opportunities will be discovered as the vehicle is being serviced. If you’re not already doing so, always encourage your customers to keep their vehicle maintenance up to date. And, just as important, let them know your techs are

The Evolving Oil Change Market

The only constant in the oil change business is change itself, especially if you’re trying to maintain an inventory of engine oil for all makes and models of vehicles. Since Volkswagen began ­requiring application-specific engine oil in the mid-1990s, the oil change business has (pardon the pun) “changed.” While many Asian vehicles ­currently require only

Internal Engine Oil Consumption Diagnostics

Due to the variables in engine design and ­operating conditions, internal engine oil ­consumption complaints are often the most difficult to solve. In some cases, oil consumption might be more severe under low-speed operation, in other cases, high-speed operation and, in some cases, intermittent. But, in any case, excessive oil consumption can drastically reduce oxygen

Hyundai Fuel System, Emissions Diagnostics

Hyundai has done a good job of improving its ­offerings over the years from both an aesthetic and mechanical viewpoint. Complemented by a strong warranty and good value, the carmaker has been able to increase its market share year over year. If you aren’t seeing these cars in your bay, it’s only a matter of

Kia: Added Grounds Can Set Codes

Additional grounds can typically benefit a vehicle’s electrical system. That is, unless the vehicle is a 2008-to-present Kia equipped with a battery sensor. If an extra ground cable is installed on the negative battery terminal, it can cause the battery sensor to send incorrect information to the engine control module (ECM), which can generate all

How Ride Height Affects Toe Angle

How can a mysterious case of tire wear occur in a perfectly aligned vehicle? It happens and the answers aren’t always simple. To better explain, let’s go back a few decades when I aligned a 1983 Mitsubishi rear-wheel drive (RWD) pickup, only to have it return a month later with a tire scuffing complaint. My conclusion was that many independent front suspensions often require a “custom alignment” to compensate for variations in ride height caused by uneven loading.

Curing Volvo Manual Transmission Rattle

In an effort to increase fuel efficiency, today’s engines produce more torque so they can be ­driven at extremely low rpm. ­Reduced viscosity engine and gearbox oils, less vehicle weight and improved aerodynamics also contribute to better fuel economy. But there’s a downside to this trend: resonant vibration. The dual-mass flywheel (DMF) is designed to

Saab Front And Rear Spring Replacement

I bought my first Saab 28 years ago, the year after I started working at The Swedish Solution in 1985, and have been driving one ever since. When everything is working right, I believe it’s one of the nicest cars on the road. I’m partial to the 2004 and up 9-3 sports sedan; it’s fast, fun

Mazda6: Data Gathering Is Critical To Your Alignment Diagnosis

About a year ago, I got a request from a private vehicle owner to help diagnose a steering problem on a 2010 Mazda6 iSport. Given the power of the Internet, it seems that this person had somehow discovered one of my older Diagnostic Solutions columns on alignment problems. While I’m not fond of dealing with
