A Closer Look: Blower Motor Resistor Operation

In service since 2011, the Chrysler Pentastar 3.6L engine has powered more than 10 million of the most popular vehicles on the road. These Pentastar engines are equipped with oil filter housings, which contain the oil filter, sensors, and a heat exchanger to help cool the oil. The oil filter housings on the Pentastar V6 engine have become known for their high failure rates. These failures have mistakenly been attributed the idea that the housings can warp due to heat, but this has been proven false. So, why do these units typically leak? 

Variable Valve Timing (VVT) or Variable Cam Timing (VCT) is common on most newer engines. These systems are designed to reduce emissions and maximize engine performance and fuel economy. Here's some background on VVT and a few tips for dealing with issues that come up.

Variable Valve Timing (VVT) systems help reduce emissions and maximize engine performance and fuel economy. The VVT Solenoid (Oil Control Valve) meters the oil flow to control the actuation of the VVT Sprocket (Actuator or Phaser). The VVT Sprocket mechanically shifts the position of the camshaft. Here are a few tips for testing.

Turbocharged engines are becoming more popular, as vehicle manufacturers look to increase fuel efficiency, maintain performance and reduce emissions. Symptoms of a malfunctioning turbocharger include loss of power, excess smoke, high fuel consumption, overheating, high exhaust temperature and oil leaks from the turbo. Here are a few important diagnostic and repair tips to keep in mind.

The Tire Pressure Monitoring System (TPMS) is a safety device that measures, identifies and warns you when one or more of your tires is significantly under-inflated. Standard® and Intermotor® are committed to helping technicians with TPMS repairs, whether it’s offering OE-Match TPMS sensors or providing repair tips from our team of ASE-certified master technicians. Here are a few TPMS repair tips.

The Mass Air Flow (MAF) sensor is a key component of the engine’s fueling strategy. It is crucial that the MAF sensor reports with 100% accuracy to ensure peak performance, fuel economy and reduced emissions. Here are some helpful tips such as how and when to replace them and steps to extend their longevity.

Coil-on-plug assemblies are designed to convert a low voltage (primary side) to a high voltage (secondary side) to fire the spark plugs. They perform the functions of both the ignition coil, which creates the spark energy, and the spark plug wire set, which delivers the high-voltage energy to the spark plug. Today's coil-on-plug assemblies come in a variety of physical and wiring configurations.

Diesel Engines have become more popular thanks to a steady string of advancements. New engine designs, noise and vibration-damping technologies, and improvements like electronic engine control have spawned a new generation of engines that are more powerful and fuel efficient than similar-size gasoline engines. Learn more about today's diesel engines with these repair tips from our team of ASE-certified master technicians.

In an effort to increase fuel efficiency and elevate performance across today’s vehicles, nearly every manufacturer has equipped new vehicles with Variable Valve Timing (VVT) technology, also known as Variable Cam Timing (VCT).

Turbocharger Opportunities: In an effort to increase fuel efficiency, maintain performance, and reduce emissions, vehicle manufacturers are adding turbocharged engines to their lineups at a significant rate. Over the next five years, the turbo service market will continue to experience substantial growth.

Turbochargers consist of just three major internal components: the turbine, the compressor and the bearing system that supports the turbine shaft. In an effort to increase fuel efficiency, maintain performance and reduce emissions, vehicle manufacturers are adding turbocharged engines to their lineups at a significant rate. 

The Tire Pressure Monitoring Systems (TPMS) is a valid safety device that has been mandated for years. TPMS introduced a lot of new terminology – initiate, program, activate, clone, protocol and relearn. This safety system, a prime service opportunity, warns drivers of issues with their tires and protects motorists from potential danger.

Hybrid vehicles have been sold in the U.S. for over 20 years. As hybrids continue to grow in popularity, and as fully electric vehicles have entered the market in the past several years, they have brought with them numerous service opportunities for aftermarket repair facilities. Whether shops dive in and get involved with replacing batteries, inverters, or other high-voltage components, or they stick to light-duty servicing, there is plenty of work to go around.

Engine misfires, rough idle, a decrease in power under acceleration, poor fuel economy, and a check engine light are all signs of an ignition coil that has failed. OE coils are known for their high failure rates. Read along for more information on ignition coils, how to diagnose a failed one, and why an original equipment manufacturer’s coil may not be the best replacement choice.

Gasoline direct injection (GDI) is used on most new vehicles and requires a different approach to diagnosis and service. GDI technology has been an integral part of helping to improve fuel economy while reducing emissions and can be found in more than half of the U.S. fleet. In fact, the use of GDI engines has grown by over 600% since 2010. This means that in the next five years, 42 million more vehicles with GDI will enter the Aftermarket “Sweet Spot” of 6-12 years old, during which their injectors and related parts may need to be serviced or replaced. While GDI systems have proved effective, these systems encounter specific failures and require an understanding of how they work and how to test them when they set a code.

The Check Engine Light (CEL) is arguably one of the most effective yet underappreciated advancements in reducing vehicle emissions. Following the introduction of On-Board Diagnostics II (OBD II), the CEL is illuminated continuously if an on-board system monitor has failed a specified number of times and is negatively affecting emissions. If a catalyst-damaging event, such as a misfire, occurs, the CEL will flash. In today’s world of electric vehicles, hybrids, and partial zero-emission vehicles, many people forget that simply keeping their internal combustion engine (ICE)-powered vehicle operating as designed will help in reducing emissions.

A shop’s reputation is affected by things like accuracy of diagnosis, quality of the repair, and friendly service. Equally as important is the quality of the parts installed. If the shop does everything right, and the part fails, the customer will ultimately be upset with the shop. When a new part fails, the customer is inconvenienced again, and begins to lose faith with the shop that performed the work. This ultimately begs the question–why take a chance with inferior parts?

Advanced Driver Assist Systems have created quite a buzz over the last several years. New business opportunities continuously arise, including a new segment of mobile technicians focusing on ADAS calibrations. While ADAS may still seem relatively new, automotive service professionals have actually been servicing Driver Assist Systems for decades. Systems like power steering, power brakes, and cruise control have been assisting motorists for many years. What is different with ADAS is that there are now input devices to understand what the driver’s intent is and alert the driver to potential dangers, rather than relying solely on the driver’s sight and sound.

Anti-lock Braking Systems are intended to do exactly as the name portrays – prevent a vehicle’s wheels from locking up during a braking event. If any of the wheels lock up, the driver has less control of the vehicle and is more prone to an accident. By releasing some brake pressure to the locked-up wheel, the stopping distance will be increased, but the driver will be able to maintain control to hopefully avoid a collision. Prior to ABS, drivers were taught to pump the brake pedal when attempting to stop suddenly, or when stopping on gravel, ice, or loose pavement. Now, the ABS system does that for them.
