Service Opportunities With Stop/Start-Equipped Vehicles
A vehicle that is equipped with a stop/start system may soon be coming to your bays or might already be there on some European and Asian vehicles. These systems can improve fuel economy by 3-5 percent, depending on the driving habits of the customer. For your shop, it is essential to understand what is different on these vehicles, and how those differences might change your diagnostic approach.
Oxygen Sensor Heater Codes
One of the most difficult problems to cure is an oxygen sensor code related to the heater circuit. If you decide to just put in a new sensor and clear the codes, there is a chance the code will come back because the malfunction in the circuit is not in the oxygen sensor.

Modern Cooling System Design: It’s Not About Temperature; It’s About Powertrain
Reading engineering papers tends to be a boring exercise, but they do give technicians a new perspective on how a common automotive cooling system could actually be improved.
Heater Blowing Cold Air? It Could Be The Auxiliary Water Pump
How one component can upset your cooling system diagnostic logic.
Don’t Be A Spark Plug Zombie
The “conscious” steps you should perform during spark plug replacement, instead of performing the job like a zombie.
Identifying And Fixing Heavy Duty Filter Issues
Today’s heavy-duty engines have evolved to incorporate modern technology and adhere to emissions regulations—which means their components have had to evolve with them. For technicians, this means that when an engine problem comes up, it’s not so simple to determine the root cause.
Air Management For The FSI V6 And V8 Engines
The FSI 3.2 L V6 and 4.2 L V8 have a lot in common with the FSI 2.0 L four-cylinder engine, including carbon deposit problems. Chances are your first exposure to an Audi intake manifold will not be a driveability complaint, but rather a carbon cleaning service where the intake valves need to be cleaned.
Oxygen Sensor And Catalyst Efficiency
The catalyst efficiency monitor verifies the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within the predetermined values. The PCM compares the signals from the upstream and downstream oxygen sensors to determine the state of the converter. These “tests” are called the readiness monitors.
