100

This is the transfer of heat through electromagnetic waves and travels through empty space.

"What is Radiation"

100

It is the back bone of every internal combustion engine.

"What is the Crankshaft?"

100

The bottom of the head forms the top half of this

"What is the combustion chamber"

100

It monitors the amount of heat in the exhaust and feeds that information to the engine's computer.

"What is an Oxygen Sensor?"

100

Bore x Bore x .7854 x stroke x # of cylinders

"What is the engine displacement?"

100

These codes refer to issues with the engine, transmission, and emission systems in a vehicle.

"What are P-codes?"

200

This law states: "The more force you put on something, the faster it will move"

"What is Newton’s Second Law of Motion?"

200
Converts linear up and down movement of the piston into the circular motion of the crankshaft.

"What is a Connecting Rod?"

200

A chamber where the fuel-air mixture is burned, creating the energy needed to move the engine parts.

"What is the Cylinder?"

200

It is used to access the vehicle's computer for various tasks, such as emissions tests and diagnostics.

"What is an O.B.D.II Port"

200

This tool displays the difference between outside atmospheric pressure and the amount of vacuum (manifold pressure) in the Engine.

"What is a Vacuum Gauge?"

200

If there’s a problem with the vehicle's suspension, brakes, or steering, you’re likely to see one of these codes.

"What are C-codes?

300

This happens when heat is transferred between two objects that are in direct contact with each other.

"What is Conduction"

300

This is a belt driven air compressor that increases the pressure of air supplied to an internal combustion engine.

"What is a Super Charger?"

300

This is the main structural component of an engine. It supports and helps maintain alignment of internal and external components.

"What is the The engine block?"

300

These are generated by an onboard diagnostic system and stored in the computers memory.

"What are D.T.C.s?"

300

A measurement of fuel stability based on the pressure at which a fuel will spontaneously combust.

"What is Octane Rating?"

300

When modules in a vehicle can't talk to each other properly, this code type is triggered.

"What are U-codes?"

400

These are the Basic Requirements for an Internal Combustion Engine.

"What is Fuel, Air, and Spark"

400

These are used to synchronize the rotation of the crankshaft and the camshaft.

"What is timing belt or timing chain?"

400
Converts linear up and down movement of the piston into the circular motion of the crankshaft.

"What is a Connecting Rod?"

400

A standardized testing procedure used to measure the performance of a vehicle's onboard diagnostic (OBD) system.

"What is a Drive Cycle??"

400

A specific measurement of air & fuel in which both are completely burned.

"What is The Stoichiometric Ratio?"

400

This type of code deals with issues in systems like airbags, doors, or climate control.

"What are B-codes?"

500

This is the transfer of heat through fluids, which can be in the form of liquids or gases.

"What is Convection?"

500

This has eccentrically ground lobes to enable the valves to be opened and closed as the engine rotates.

"What is a camshaft?"

500

 It is responsible for converting the energy released during the combustion process into mechanical work.

"What is the Piston?"

500

The process in which you increase the speed of the combustion stroke.

" What is Timing Advance?"

500

A thermodynamic cycle that describes how internal combustion engines turn chemical energy into thermal energy and then into motion.

"What is the The Otto Cycle?"

500

These Cannot be reset by disconnecting the vehicle's battery or cleared using an On-Board Diagnostic

"What are Permanent DTCs ?"
