Your modern vehicle’s engine is a highly sophisticated piece of equipment. The days of your father’s gas-guzzler are long gone-instead, Federal Exhaust Emission and Fuel Economy regulations demand that today’s vehicles be equipped with electronic engine control systems to curb carbon emissions and increase fuel efficiency. With technically advanced control systems taking the place of simple engine components, common maintenance services such as tune-ups are also a thing of the past. Regular services (such as spark plug and filter replacements) are still required, as well as a computerized analysis of your vehicle’s control computer. Our factory-trained technicians are here to provide these basic services.
Here’s How Your Modern Vehicle’s Control Computer Operates:
A network of sensors and switches convert and monitor engine operating conditions into electrical signals. The computer receives this information, and, based on information and instructions coded within this savvy computer program, commands are sent to three different systems: ignition, fuel, and emission control. Whenever a problem arises (as seen by that nagging “check engine” light), our service pros check whatever command is prompted, in addition to the status of your engine control computer and sensors. That way you’ll know if your vehicle’s performance is caused by a real problem, or just a sensor/computer issue.
Mass Airflow Sensor
A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine
Throttle Position Sensor
A throttle position sensor (TPS) is a sensor used to monitor the throttle position of a vehicle. The sensoris usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle. … Modern day sensors are non contact type.
Manifold Absolute Pressure Sensor
The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine’s electronic control system. Engines that use aMAP sensor are typically fuel injected.
Coolant Temperature Sensor
Most (ECT) sensors operate using electrical resistance to measure the temperature of the coolant. The readings from the (ECT) sensor are sent back to the engine control unit (ECU). The engine control unit (ECU) uses this data to adjust the fuel injection and ignition timing.Oct 21, 2017
Exhaust Oxygen Sensor
The O2 sensor is mounted in the exhaust manifold to monitor how much unburnedoxygen is in the exhaust as the exhaust exits the engine. Monitoring oxygen levels in the exhaust is a way of gauging the fuel mixture. It tells the computer if the fuel mixture is burning rich (less oxygen) or lean (more oxygen).
Crankshaft Position Sensor
A crank sensor is an electronic device used in an internal combustion engine, both petrol and diesel, to monitor theposition or rotational speed of the crankshaft. This information is used by engine management systems to control the fuel injection or the ignition system timing and other engine parameters.
Camshaft Position Sensor
The camshaft sensor is a small, but significant, magnetic device. It gathers and sends information about the car’s camshaft speed (and as a result the position of each piston) to the car’s electronic control module. This information is received by the computer, which then uses this data to further calculate the time of ignition and the timing of fuel injection required by the engine. This information is vital for engine function.
