Tech Update: Key Cycles and Codes
OBD II brought a lot of changes regarding how a technician diagnoses a vehicle. With OBD I, a failure had to occur in order to produce a service code, while OBD II can monitor failures or even partial failures. These days, codes have become part of the normal process in determining a fault. There are several different types of codes. Beyond engine, transmission, HVAC or body codes, there’s also a way to break down the priority of some of those codes.

Turbocharger Technology Continues to Improve
With the ability to increase fuel economy by up to 20% on gas vehicles and up to 40% on diesel vehicles, manufacturers have resorted to turbochargers to compensate for lowered engine displacement. Additionally, the improvements on turbocharging technology have increased the number of turbocharged vehicles on American roads. Some turbocharger manufacturers have even projected the number of turbocharged vehicles in the U.S. to quadruple in the next five years.

Exhaust System Welding & Fabrication
Even as direct-fit exhaust systems are dominating the replacement exhaust market, there is still a need for exhaust fabrication that includes welding. Being able to weld exhaust system components is not about creating less-expensive alternatives for your customers. Being able to weld and fabricate components gives you the flexibility to provide your customer with the
Tech Tip: Every MAF Sensor Needs a Breath of Fresh Air
Sensor replacement is critical to engine efficiency because a dirty MAF sensor will not respond as fast to air flow changes as a clean sensor.
The Ins and Outs of Variable Valve Timing (VVT) Systems and Their Role in Vehicle Emissions
By the early 1990s, almost all import automotive manufacturers had a successful variable valve timing (VVT) system in production. These systems offered higher performance from smaller displacement engines at higher rpm. Do you know that VVT is playing a direct role in vehicle emissions and the way gases are burned in the combustion chamber?
Pulling Codes: The Story of Code P0456
The Smallest of Details? This month’s Pulling Codes documents the infamous P0456 code — 0.20 leak detected. A small leak code can be the most challenging for any technician, so Carlton Banks gives his suggested plan of attack.

Tech Talk – Engine Innovations to Reach Government Fuel Standards
In recent years, the primary driving force behind engine innovation has been the never-ending quest for better fuel economy with little or no sacrifice in performance. Government regulations and rising fuel prices are forcing automakers to develop new technologies and powertrains that squeeze more power out of every drop of fuel while producing less pollution and greenhouse gas (carbon dioxide) emissions.
