Drivability means a car's ability to drive. Technicians and service experts alike determine a car’s drivability by adhering to a condition checklist.
Drivability refers to anything having do with how your vehicle is performing while on the road. From the fuel system to affected components and other systems like the Powertrain, ignition, distributor, exhaust system, brakes, tires, suspension etc... the list is endless. With the proper diagnostics, the problems are zeroed in on and solved before they become a major issue.
In many situations, the more common problems surface because we neglect or are unaware of proper care of our car. Electronic systems are one example, emissions are another. They can be a delicate pieces of equipment. Frequent or scheduled drivability diagnostics checks should be preformed. What are some of the commonly occurring problems you may see in a vehicle? Intermittent stalling of engine... some of the known causes include a worsening Idle Speed Control (ISC) System, ignition loss, low fuel pressure, EGR or vacuum leaks and many more. The Idle speed of every engine is manipulated through the amount of air that is permitted to bypass throttles using the idle bypass circuit witch is located within the throttle body. The Powertrain Control Module then monitors the idle speed, and it utilizes a solenoid, a small electric motor to position a valve that manipulates the airflow through air bypass circuits. If a sensor in this system fails, it could be the cause of your problems. A diagnostics check could find the issue and repairs can be made.
Aside from that, the analysis will also seek out any problems that hamper your vehicle engines performance, such as;
* Idle smoothness. Hot and cold starting procedures. * Efficient throttle responses. * Effective power delivery.
Many complaints directed to drivability issues may be more serious than the average concerns. In these situations, such issues are verifiable and better addressed via a more in-depth scanning and diagnosis by qualified technicians with the latest test computers and diagnostic equipment. Modern vehicles have their own special diagnostic requirements. Skilled technicians updated with the current procedures, techniques and new technologies are the most qualified to conduct such diagnostics.
