FOND DU LAC, Wis. — The technical services team at Wells Vehicle Electronics has released two in-depth video case studies covering mass air flow (MAF) and variable valve timing (VVT) diagnostics. Available in English and Spanish, the new videos join more than 40 other free diagnostic case studies available through the company’s website and the “WellsTech” YouTube channel.
 
Produced in the company’s diagnostic repair lab and media tech garage in Fond Du Lac, Wis., the new videos are:
 
P0171 Mass Air Flow Diagnostics
This six-minute video features a 2002 Buick LeSabre equipped with a V6 engine. The owner had reported declines in power and fuel efficiency and the “Check Engine” light was illuminated. Based on the stored trouble code – P0171 – the WellsTech diagnostician isolated the problem from a wide range of possibilities, including faulty MAF sensor, vacuum leak, restricted injector, low fuel pressure, malfunctioning oxygen sensor and plugged PCV valve. Tools used in the diagnosis were a lab scope (to check MAF and throttle position sensor signals) and scan tool.
 
P0014 And P0306 Variable Valve Timing Diagnostics
The subject vehicle, a 2002 Chevrolet Trailblazer, exhibited a variety of drivability symptoms, including loss of power, reduced fuel efficiency and rough idle. Two trouble codes – P0014, indicating a cam phasing error; and P0306, cylinder 6 misfire – had been stored. The diagnostic process included testing, removing and inspecting the variable cam timing solenoid and analyzing current draw to the cylinder. The WellsTech diagnostician used a scan tool and lab scope in identifying the root cause.
 
Researched, written and produced entirely in-house by the Wells Technical Services team, each Wells video case study tackles a complex diagnostic challenge commonly encountered in automotive service facilities. The point of each segment is to help the technician complete a thorough and accurate diagnosis in the most efficient and effective manner possible. The videos have attracted more than 5.8 million views and 10,500 subscribers through multiple YouTube channels.
 
“The popularity of our videos demonstrates the demand among technicians for information that can help them save time in accurately diagnosing and repairing drivability issues. There is no product promotion or selling – our sole mission is to help the viewer find and fix the problem through the use of easily accessible tools and proven diagnostic procedures,” said John Zochert, director of marketing and product management for Wells Vehicle Electronics.

This is always an important topic to discuss, because I consider excellent customer service one of the most important tools you can have to earn trust, respect and repeat business from the customers that come through your door. Whether that customer is do-it-yourselfer from across town or the professional repair shop across the street, your business depends on a solid relationship.It’s a subject that I am passionate about, and it’s one that many people are losing touch with. Whether you are communicating to someone in person, on the phone or using some type of social media, good customer service and bad can both exist. You can’t afford the latter, so this is the first in a series of topics which can and should be shared from the front of the shop to the back. No matter which role you hold, you represent the shop and yourself. Customer service should be your number one priority.First on the list is the greeting. From the second a customer walks in the door, they need to know you appreciate them coming in and how important they are to your business. First impressions are everything and here’s the correct way to do it each and every time: look them directly in the eye, smile and say hello!Of course, you can say “Good morning” or “Welcome to Joe’s Autocare,” but it should be a formal greeting and the most important thing is that you have smiled, looked them in the eye and recognized that they have walked through the door.You should always retain a formal greeting until you are on a first-name basis with a customer. Only once you have established that level of relationship is it OK to use the less formal greeting of “Hi,” followed by the person’s name.This greeting does more than just indicate respect and appreciation for someone walking through the door. Most likely there are customers both new and old who are in earshot of your conversation. For newer customers, this continues to build rapport and reinforce their positive view of your shop; they see that you demonstrate respect and treat everyone in the same manner. For repeat customers, even ones that have been coming for years, the greeting is important because the way you treat them is the reason they continue to come.And when a long-time customer comes in and you greet them with “Hi [First Name],” this indicates your appreciation for them and that you’re glad to see them as a person, more than just a customer. New customers that witness this will see that your repeat customers are comfortable enough to be on a first-name basis, another indication of the trust they have in you.
