TPMS Signal Science: Performing The Relearn Process Outside
While TPMS is common on today’s vehicles, misinformation is still rampant as consumers and techs try to understand these systems. One of the TPMS misconceptions involves sensor signals. A sensor is a transmitter of information that sends pressure and temperature data to the vehicle. Some signals also include information that identifies the sensor and the
Aging Oxygen Sensors Hurt Fuel Economy, Performance And Emissions
Oxygen sensors are used to monitor the engine’s air/fuel mixture so the powertrain control module (PCM) can make adjustments that optimize fuel economy, emissions and performance.
The Art Of The Refinish: Making An ‘Invisible Repair’
There is a lot that goes into making an “invisible repair” from the refinish side. Here are some procedures to get you off to a good start.
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
Understanding Collision Warning & Automatic Braking Systems
Anything that moves under its own power also has to stop, so brakes have been a safety feature on cars since day one. Over the years, technical innovations such as anti-lock braking systems (ABS) have improved the ability to stop with minimal skidding on wet or slick surfaces. The addition of stability control allowed each
Do’s And Don’ts Of Head Gaskets
Do: Clean the Holes To ensure accurate torque values and to avoid cracking the cylinder block, clean any dust, dirt, oil and fluid from the cylinder block head bolt holes before installing the new head gasket and head bolts. Never lubricate the head bolts with a friction-modified oil. Unless otherwise specified, lightly lubricate the bolt
Component Connection: Gasket Q & A
Question: When replacing gaskets on an engine, do I just scrape or peel off the old gaskets, or do I have to do something else? Answer: Removing gaskets used to be a fairly simple procedure. Most engines used to have cast iron blocks and heads, with iron manifolds and stamped steel covers. Iron castings could
Next Generation Start/Stop Systems
Although stop/start idle systems have been used on hybrid vehicles for many years, a growing number of non-hybrid late-model import models are also being equipped with this fuel-saving technology.
Aluminum In The Paint Shop – What You Need To Know
There has been a lot of buzz since the 2015 Ford F-150 – largely comprised of aluminum – was released. And rightly so!
Getting Grounded: Positive And Negative Energy Sources
When it comes to electricity, there are two potential energy sources you have to keep in mind. One, being the positive side, and the other, the negative side.
