Tech Tip: Ford Truck No-Start Following CKP Replacement

After replacing the Crankshaft Position Sensor (CKP) and/or connector to correct another problem, the engine turns over, but does not start. The fuel injectors pulse a couple of times when the engine starts cranking, then they stop pulsing. There is an rpm reading on the scan data for a split second, then it goes to zero. There is no spark. More

Tech Spec: 100 Years of Changing Internal Combustion Technology

It would be interesting to hear what Nicolaus Otto, credited as the father of the first functional four-stroke IC engine, would say after seeing some of the advanced powerplants dropped into vehicles today. More

Directions: New Engine Oil Specification to Flow into Shops this Year

The International Lubricants Standardization and Approval Committee (ILSAC) is finalizing the latest next-generation of motor oil specifications that will hit the market later this year. More

Talking Shop: An All-Access Pass to Shop/Repair Information?

If you've spent hours struggling to master a new computer software system, you can well understand how a modern auto technician might feel when confronted with not just one, but hundreds of different software configurations built into the platforms of the 17 different vehicle manufacturers now being sold in our domestic market. More

New Emissions Technology: Fuel Economy, Global Warming & Alternative Fuels

We can expect to see more innovations designed to improve fuel economy and/or eliminate our dependence on oil altogether, says Technical Editor Larry Carley. That means more direct-injection engines, more emissions control complexity, more clean diesel engines, more hybrids and eventually mass-produced, full electric vehicles. More

Tech Feature: Diagnosing Ford Exhaust Gas Recirculation System Problems

To diagnose and repair Ford exhaust gas recirculation (EGR) systems properly, it is important to understand how they work and what is unique to the product line. More

Directions: The Impact of HF0-1234yf on Service Shops

According to the new refrigerant's developers, there are chemical differences between HFO-1234yf and the current R-134a system. As a shop owner, you'll need to learn the Safety, Equipment and Charging Issues surrounding this new refrigerant. More

Tech Feature: Detecting Misfires in OBD II Engines

With OBD II, there's no missing misfires. Most engine control systems with OBD II monitor the speed of the crankshaft between cylinder firings to detect misfires. The powertrain control module (PCM) notes the relative position of the crankshaft via the crankshaft position sensor (CKP) each time a trigger pulse is sent to the ignition system. More

Tech Tip: GM Mass Air Flow Sensor Failure

Instances of repeated Mass Air Flow (MAF) sensor failure on General Motors applications utilizing the remote-mounted Delco unit can often be traced to an engine back-fire condition. The sudden intake pressure buildup can induce cracking of the heated element resulting in MAF sensor failure. More
