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.

Tech Tip: Fuel Filler Necks And Related Check Engine Light Conditions

Since the introduction of the OBD II system, manufacturers have continued to improve on the monitoring of evaporative emissions, with the complete evaporative system being under a scrutinized surveillance. Codes like P0440 to P0456 are all related to the fuel vapor control, including leaks.

Tech Tip: A Day In The Life Of A Contaminated O2 Sensor

Since the oxygen sensor is in the exhaust stream, it can become contaminated over time. Much like a spark plug, the oxygen sensor can be examined and “read” to determine what the cause of contamination might be.

CORSA Performance Publishes 2013 Product Line Catalog

CORSA Performance Exhausts has released a new, four-color, 40-page catalog featuring all product applications for CORSA Performance Exhaust Systems, dB Performance Exhaust Systems, as well as the company’s new air intake line.

Emissions Control Diagnostics Workshop Teaches Strategies For Profitable Repairs

With more than 60 events on the schedule for 2013, the Walker Emissions Control Diagnostics Workshop from Tenneco will target more than 4,000 attendees in the United States and Canada, with the aim of teaching new strategies for effectively and profitably diagnosing emissions control and drivability repairs.

Kia Tech Tip: Check Engine Light Is On

The check engine light is on and there is a mass air flow (MAF) sensor range/performance code in the system. The engine will hesitate at times. The P0101 code is more of a rationality check. The MAF sensor signal isn’t rationally making sense comparing to things like throttle position and engine rpm.

Bosch Expands Its O2 Sensor Line; Adds 82 New OE-Fit Part Numbers

Bosch has expanded its line of oxygen sensors to cover applications through the current 2013 model year. The 82 new OE-fit sensors cover 21.9 million vehicles in the United States and Canada including a variety of domestic and import applications – both Asian and European. Besides a host of passenger cars, minivans and SUVs, the new coverage also includes several hybrid vehicles.

Dorman Products Releases May New Product Announcement

Dorman Products has released its May New Product Announcement, featuring 400 new parts, 109 of which are exclusive formerly “Dealer Only” parts.

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.

Delphi Launches Latest Emissions Standards Guides, Now Also Available As An Interactive App

The popular Delphi Automotive Worldwide Emissions Standards booklets provide easy-to-read summaries of emissions regulations from around the world. An updated 2013-2014 edition for passenger car and motorcycle emissions standards is now available. New this year, this version, together with the heavy-duty and off-highway commercial vehicles edition, are available as an interactive app for iPad users.

Tech Feature: Hall Effect Sensor Diagnostics

Hall effect crankshaft position (CKP) and camshaft position (CMP) sensors are critical components of an engine management system. The inputs they provide enable the powertrain control module (PCM) to determine engine speed and position including where a given cylinder is within the four-stroke cycle.

Diagnosing A 2011 Chrysler Town & Country With Trouble Code P0152

Verify the wiring to the O2 sensors is normal. These sensors will normally switch between 2.5 volts and 3.5 volts when they are working correctly. The sensor ground will have 2.5 volts on it and this is normal for this vehicle.
