Emissions
100
Blue colored smoke out of the tailpipe is an indicator this is being burned in the engine
Engine Oil
100
This is the standard amount of engine vacuum at idle
17-21 inches
100
The name of this component:
Wheel Cylinder
100
Component used to reduce a vehicles body roll while going around a corner
Sway Bar/ Anti- Roll Bar
100
This component stores fuel vapor to be burned in the engine
Charcoal Canister
200
If this component fails, excessive external oil leaks and oil consumption can occur
PCV Valve
200
A positive fuel trim at idle that gets better when under load indicates this condition
Vacuum Leak
200
A spongey brake pedal is most often caused by this
Air in the brake hydraulic circuit
200
This calibration should be performed after every alignment on a vehicle with VSC
Steering Angle Sensor/ Zero Point Calibration
200
Excessive amounts of this gas in the exhaust indicate a lean engine condition
Carbon Monoxide (CO)
300
Excessive exhaust back pressure is most likely cause by this failure
Clogged Catalytic Converter
300
A restricted air filter will cause this fuel trim
Negative Fuel Trim (Rich Condition)
300
This component is responsible for opening and closing solenoids in the the brake hydraulic circuit during hard stopping maneuvers
ABS Actuator
300
This alignment angle is abbreviated as SAI
Steering Axis Inclination
300
This component is used to reduce the amount of NOx produced by an engine
Exhaust Gas Recirculation Valve (EGR)
400
A stuck closed exhaust valve will cause this compression reading
Higher than normal/ specification
400
If this component does not open, it will result in a "overboost" condition on a turbocharged car
Wastegate
400
This failure will cause this wheel speed sensor signal: 
Damaged Tone Wheel
400
This alignment angle is created by the rear toe
Thrust Angle
400
A vehicle that stalls immediately after the customer pumps gas is caused by this valve being stuck open
Purge Valve
500
This high performance engine oil lubrication system pulls oil directly from a reservoir and not the oil pan like a typical engine
Dry Sump Lubrication System
500
This type of fuel injection system calculates engine load without using a MAF sensor
Speed Density
500
This component limits brake pressure to the front wheels until enough force is applied to the brake pedal on some older models
Metering Valve
500
A vehicle has more positive caster on the driver side than the passenger side will pull in this direction
Right/ Towards Passenger Side
500
A completely flat line during a Key-Off EVAP system test is caused by this component not operating
EVAP System Vacuum Pump
