In this article the problematic subject vehicle was brought to an Autologic equipped shop by a neighboring repair shop. They were fighting a reoccurring P0339 that would set once on average once per day.

To reduce the carbon footprint of cars and trucks worldwide, many automotive engineers, designers and manufacturers are pushing to expand the feasibility, supply and affordability of all-electric vehicles. A primary focus is the development of a battery for efficient energy storage.

See how to relearn the misfire correction profile on Ford engines. In this video the procedure is shown using Ford IDS or FJDS via Pass-Thru on a Farsight tablet.

Knowing these four pattern failures of the ME97 engine controller for the 272-273 engine can help expedite your diagnosis and avoid replacing the wrong parts.

The customer was driving this vehicle and the engine suddenly cut out, they had it towed to the shop. At the shop it would crank and start, but would idle at only 300 rpm. After a short time, the rpm would drop and then the engine would stall.

When servicing the crankshaft pulley or crankshaft sensor, it is important to check sensor to trigger wheel alignment. If timing is incorrect you could have a hard start, fault codes or a no start condition.

In this technical article and video, Ford universal gas oxygen sensor (UEGO) sensor design, function and testing will be covered. Found in most modern Ford Gas engines inclduing Ecoboost.

The automotive business was much simpler when I first started. Mechanically, cars were far less complex, easier to fix, and most repairs could be handled with basic hand and air tools. Most shops expected mechanics to provide these tools to repair the types of vehicles the shop serviced. It had always been that way. Tools were a personal thing, like an extension of yourself, a glove or a shoe. Since the tools were basic, you didn’t need a whole lot, and they were reasonably affordable, it was easy to expect a new hire to provide everything they needed.

In this technical article, we will cover the design, function and how to test and diagnose issues with Hot Film Mass 6 Air Flow Sensors, also known as HFM6 sensors. This is the next generation in hot film air mass sensors.

This article will review a technical help request from a shop for a 2009 Audi A4 running rough and setting fuel trim fault codes.

The following fault codes were stored:

• P0171 System Too lean
• P12A2 Fuel Rail Pressure Sensor Too high
• P0507 Idle Air Control System RPM Higher Than Expected
• P2279 Intake Air System Leak
• P0300 Random Multiple Cylinder Misfire
• P0301 Misfire Cylinder 1
• P0302 Misfire Cylinder 2
• P0303 Misfire Cylinder 3
• P0304 Misfire Cylinder 4

In this technical article, we will cover the design, function and how to test and diagnose issues with Hot Film Mass 5 Air Flow Sensors, also known as HFM5 sensors. These sensors are responsible for reporting air-mass volume to the engine control module for precise air fuel control.

This technical article will cover the design, function and how to test piezoelectric knock sensors on gasoline engine equipped vehicles.

If the iDrive screen on a late model BMW is frozen and does not react to iDrive knob or button inputs, you may need to reset the display. This is the first step in the diagnostic process for inoperative iDrive screens.
