The journey marks the first time that a fuel-cell electric car has achieved Level 4 autonomous driving at such a long distance and at speeds up to 110 kmh (68 mph), according to Hyundai.
Understanding Diesel Exhaust Filters
The Diesel Particulate Filter (DPF) is a ceramic filter that has thousands of tiny channels or honeycomb-shaped openings that trap the soot onto the channel walls and prevent the particulate matter (down to 1 micron) from exiting out the tail pipe.

Participants of NGK’s first CASE-certified training
Engine Design: A Changing Diagnostic Approach
Modern propulsion technology requires high-speed data processing systems. For that reason, our relearning process actually began when CAN bus electronic systems were introduced by Mercedes-Benz circa 1990.
2002 Lexus Evaporative Emissions Diagnostics (Codes P0440, P0441 and P0446)
While old-school cooling system service often focused on coolant leaks and overheating engines, let’s begin thinking “new-school” by looking at modern cooling systems through the eyes of the engine coolant temperature (ECT) sensor. Coolant temperature is important because torque converter clutch engagement, idle speed control, variable valve timing, engine cooling fan operation and various other
Toyota: Rough idle, surging between 500 to 800 RPM
Model: 2005 Toyota Avalon and some models with similar system configurations, such as 2006 Camry models.

Toyota Tech Tip: Rough Idle, Surging Between 500 To 800 RPM
The owner of 2005 Toyota Avalon complains check engine light is on, rough idle and engine idle surging between 500 and 800 rpm. The technician retrieved Diagnostic Trouble Code (DTC) P0171 and P0174 (System too lean banks 1 and 2). The technician replaced the air fuel sensors on both banks and cleared DTCs. After driving vehicle for approximately one mile, all symptoms returned.
10 Signs A Fuel Injector Needs To Be Replaced
In the past 30 years, the fuel injector has moved from the intake manifold to the combustion chamber. During this evolution, injectors have become more precise in dispensing fuel. If this precision is thrown off by restrictions, electrical problems or fuel problems, it can cause driveability issues. These are the top 10 signs fuel injectors need service or replacement.
Contaminated Fuel Can Wreck Havoc On Fuel Delivery Systems
Although cases involving contaminated gasoline are relatively rare nowadays, they still occur. In many cases, the technician has replaced the fuel pump or mass air flow (MAF) sensor to address a P0171/P0174 “lean-condition” DTC with no result. In all likelihood, the technician didn’t consider the possibility that the vehicle’s fuel might be contaminated with E85 gasoline, diesel fuel, stale gasoline, or, to a lesser degree, sugar and water.
