Lock Technology Offers O2 Sensor Removal Kit

The Shockit Socket O2 Sensor Removal Kit from Lock Technology features a low-profile design for limited access and long-profile design for deep recessed applications.

Oxygen Sensors: Pulse Measurement

Watching an oxygen sensor output on an oscilloscope is like watching a sporting event on television. You get to see the action, but can do nothing about it as it happens. Sometimes you miss the action and want an instant replay. It was a bad call. You saw the interference. If the referee didn’t see

OBD II Misfire And Diagnosis

When diagnosing misfires, it’s important to use tools that allow you to go beyond a simple code reader that displays a P03XX. Even an OEM-level scan tool can’t tell you what the firing voltage is or what the ignition pattern looks like. Nor can it tell you if the serial data is accurate or correct. For that kind of information you need a DVOM or a graphing multimeter/oscilloscope that can look at sensor voltages directly and display primary and secondary ignition patterns.

Pulling Codes: O2 Sensor Heater Circuit Malfunction

Pulling a P0135 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) code means you’re dealing with a possible oxygen sensor heater element and/or associated components in this circuit. This article provides a game plan for diagnosing a vehicle with this code.

Diagnosing EGR And Secondary Air Systems

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. We are not there yet. In the mean time, we have exhaust gas recirculation systems (EGR), secondary air injection and catalytic converters.

ASE Undercar X1 Specialist Certification: Not What You Would Expect

Are you one of the 7,570 technicians who are ASE-Certified Undercar Specialists? If not, you should be. I recently took the X1 Exhaust Test to qualify as an Undercar Specialist. To gain this certification you must be concurrently certified for Suspension & Steering (A4) and Brakes (A5) from the Automobile & Light Truck Test Series, and Exhaust Systems (X1) from the Specialty Test Series.

Spectra Premium Introduces 88 New SKUs

Spectra Premium Industries releases 88 new parts covering a total of 24 million vehicles in operation, comprised of late-model domestic and import applications.

TECH TIP: Using a Five-Gas Analyzer to Diagnose Catalytic Converters

One of the most effective ways to resolve emissions issues is by sampling the exhaust gases with a five-gas analyzer. Levels of the five gases can indicate the root cause of the problem.

Delphi Product & Service Solutions Announces 16 Oxygen Sensors Covering Almost Two Million Vehicles

Delphi Product & Service Solutions (DPSS) announces 16 new oxygen sensors covering more than 1.9 million Ford, Honda, Toyota, Mitsubishi, Cooper, GM, Nissan, BMW, Suzuki and Mazda vehicles from 2004 to present.

DENSO Makes It Easier To Find The Right Oxygen And Air/Fuel Sensors

DENSO has just released their 2013 First Time Fit Oxygen and Air/Fuel Sensor Catalog that offers one of the most complete product lines in the industry, said the company. It includes 67 new oxygen sensor part numbers to cover an additional 7.7 million units in operation.

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.

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.
