Engine Series: Cummins Diesel Powers Dodge For Nearly 25 Years
When you hear the name Cummins, what is the first thing that comes to mind? Most of the time, if you have any knowledge of trucks, a Dodge truck is the first thing that comes to mind. The Cummins diesel engine has always had a great reputation for reliable diesel power. Though the Cummins diesel engine can be found in many applications, it seems to obtain most of its credit from drivers of over the road trucks.
Diagnostic Solutions: Extended Oil Change Intervals
Extended oil change intervals are a mixed blessing. On the upside, extended oil change intervals are conserving precious oil and reducing carbon emissions. On the downside, many vehicle owners are forgetting to check their engine’s oil level between oil changes. The most common result is an engine ruined by excess accumulations of varnish and sludge due to using motor oils that are not approved by the engine manufacturer.
Preventive Maintenance: When Should Fluids Be Replaced?
Unfortunately, many shops have been accused of over-selling fluid maintenance services. For example, I had a customer who, for whatever reason, preferred to have his vehicle serviced at an out-of-town fast lube shop. Although his vehicle recently had the automatic transmission replaced, the fast-lube shop insisted on selling him a transmission fluid flush. Not only did they sell him the first transmission flush, they attempted to sell him a second flush on a later visit.
Determining When An Oxygen Sensor Needs Replaced
When diagnosing any oxygen sensor, remember that outside air entering the exhaust system from an exhaust leak will obviously reduce an oxygen sensor’s indicated voltage output. It’s also important to know that oxygen sensors can become rich or lean biased due to problems like sensor contamination and faulty sensor grounds. Remember that, regardless of how well it tests, a biased sensor will not produce a stoichiometric air/fuel ratio. So, if the sensor is questionable, it should be replaced.
Diagnostic Solutions: Contaminated Fuel Can Wreck Havoc On Fuel Delivery Systems
Import Specialist Contributor Gary Goms discusses how contaminated fuel can mimic the symptoms produced by defective fuel pumps, fuel injectors and fuel control components like mass air flow (MAF) sensors. Although cases involving contaminated gasoline are relatively rare nowadays, they still occur. In many cases, the technician has replaced the fuel pump or MAF sensor to address a P0171/P0174 “lean-condition” DTC with no result.

How Do The EGR And Secondary Air Injection System Work With The Catalytic Converter?
The perfect internal combustion vehicle would be able to put the exact amount of fuel and air into the combustion chamber. If the perfect combustion event happened, you would get nothing more than water and carbon dioxide. There would not be any unburned fuel or oxygen. It would also be at the right temperature so

Diagnostic Solutions: Oxygen Sensor Inspection And Service
Oxygen sensors have been a part of the automotive maintenance scene since 1976, when feedback fuel controls were popularly introduced. By 1980, nearly every car and light truck was equipped with an oxygen sensor that allowed their computer-controlled fuel systems to operate in a “closed-loop,” “feedback” or “fuel control” mode.
