Automotive Evaporative Emissions - Part One
From www.autofixworld.com: Part One of a two-part video describes how
onboard monitors test vehicle fuel containment systems for fuel vapor
leaks. Three types are discussed: pressure test; vacuum test; and natural
vacuum leak detection.
How to Fix A Check Engine Light : P0455 Emissions Purge Valve Replacement
A check engine light can be caused by many different problems. Fortunately
the ECM will generate and store a code when a component fails or near
failure. This points us in what direction the issue is and guides on the
The automobile consist of:
• Fuel System: Purpose is to deliver fuel to the engine. It consists of
the fuel tank, pump, gauge/sensor, filter, pressure regulator and
• Air Intake System: Purpose is to clean and direct outside air into the
engine. It consist of air filter, ducts, air plenum and intake manifold.
• Exhaust System: Purpose is to
direct Exhaust gasses out of
combustion out of engine. It consists of the Exhaust manifold, converters, pipes and
• Cooling System: Purpose is to remove excess heat from the engine. It
consists of water pump, hoses, radiator, thermostat, cooling fan and
coolant recovery tank. Also the oil system serves as a cooling system as
well as a lubricating system. It consist of oil pump, pan, filter and
1. Clutch: Purpose is to connect the engine and transmission together. It
consists of clutch drive disc, driven disc, release bearing, clutch fork,
cable, slave cylinder, master cylinder. There are three types of clutch
systems: mechanical, cable and hydraulic.
2. Transmission: Purpose is to match engine speed to road speed. Two types
used are manual or automatic. These consist of gears, linkages, cables and
converters for automatics. A manual is connected to the clutch by a
flywheel and automatic by a flexplate.
3. Driveshaft: Purpose is to connect the transmission to the rear axle. It
consists of a slip yoke, shaft and universal joints.
4. Rear axle differential: Purpose is to change the angle of motion from
engine to the wheels. It also divides torque between the wheels. It
consists of a ring and pinion gear, carrier, bearings, crush sleeve and
5. Wheels/Tires: Purpose is to provide traction to the road as well as
carry the weight of the vehicle.
Vehicle Control Systems:
1. Brakes: Purpose is to slow and stop the vehicle. It consists of master
cylinder, brake Booster (vacuum or
hydraulic), calipers, drums, pads and rotors.
2. Steering: Purpose is to direct vehicle in the required direction.
Consists of steering gear (rack & pinion), steering wheel, column,
inner/outer tie rods, pump, reservoir, hoses and pipes.
3. Suspension: Purpose is to provide stability and handling while also
providing comfort to the ride. Consists of shocks, struts, sway bars, end
links, springs, trailing arms and bushings.
1: Heating Ventilation Air Conditioning (HVAC): Heats and cools interior
air to passenger comfort. Also circulates outside and inside air.
• Air Conditioning: Consist of condenser, compressor, accumulator
(receiver/dryer) orifice, expansion valve, hoses, evaporator, controls,
actuators and modules.
• Heating: Consists of heater core, valves, hoses and switches.
1. Power Generation: Creates electrical power to run all the electrical
systems. Consists of the alternator.
2. Power storage: Stores unused power to start the car and supply voltage
to the alternator to create more electricity.
• Both systems consist of wiring, harnesses, fuse, relays and modules.

EVAP System Operation
EVAP System Operation

Explain the operation of the EVAP system. The EVAP system is in charge of
recovering the excess fuel vapors and re-introducing them into the engine.
It isn't just an emission system. If it malfunctions is also has a huge
effect on engine performance and certain components operation will be
cancelled by the ECM if the EVAP system fails. Learn how they operate here
and how to test. The OBD-II scanner or Scan-1 is used to diagnose these
systems and evaluate the process. See how it works.
