A vehicle may qualify for a waiver if: - ANS Failed initial and retest Owner presents the VIR from failed test Presents a completed repair data form Owner has documentation indicating that the cost limit has been met. Repairs have been made within the 60 days Repairs may include labor and electronic diagnosis performed by any recognized repair facility. Repairs on the form were actually performed Vehicle is equipped with all emissions system components as originally installed by the manufacturer Air pollution - ANSContamination of the atmosphere by gaseous, liquids or solid wastes or byproducts. Emitted from natural or human-made sources. Air pumped into the exhaust helps to? - ANSOxidize exhaust gases before they enter the catalyst and helps quickly bring the catalytic converter up to operating temps. An emissions inspector must meet what requirements? - ANSBe at least 18 years of age Have a valid driver's license
Can out-of-state vehicles entering PA with a cardboard transportation tag be tested? - ANSYes! as long as the vehicle can legally be driven on the highway. Vehicle owners need to apply for registration within 20 days of entering PA. Carbon Monoxide - ANSColorless, odorless, and poisonous gas. Created when an engine burns HV in the presence of O2. Continuous monitors: - ANSEngine misfire Fuel system performance Comprehensive components Customer Hotline - ANS(800) 265- Customer is refusing to authorize an I/M test? - ANSYou may refuse to perform his/her safety inspection. Do vehicles that receive the OBD-II I/M check also receive a visual antitampering check? - ANSNO! These items are checked by the on board system. Documenting Waivers - ANSVIR from initial test failure VIR from second failure Completed repair form Receipts/invoices documenting the cost limit has been satisfied with repairs related to the failure.
Leased Vehicles are subject to... - ANSEmissions inspection based on the county listed on the registration card. Major Pollutants - ANSHydrocarbons (HCs), carbon monoxide (CO), and nitrogen oxides (NOx). (released from fossil fuels like gasoline and diesel) Most of the world's air pollution problems are... - ANSHuman-made Nitrogen Oxides (NOx) - ANSExcessive amounts can be caused by a lean air-fuel mixture, a defective exhaust gas recirculation valve, higher than normal engine temperatures, vacuum leaks, and advanced ignition timing. Non continuous monitors - ANSEGR O2 sensors Catalytic Converter Evaporative emissions system Others if equipped Non-subject Vehicles - ANSClassic, antique, specially constructed, or collectible motor vehicles (titles/registered as such). Buses with a seating capacity of 16 or more. Vehicles with a GVWR of 9,001 lbs or more 1974 and older model year vehicles
Our goal? - ANSClean air, PA emissions inspection program is part of the state's plan to clean the air and keep it clean in the future. Oxygen - ANSToo much or too little can cause improper combustion and result in pollution Ozone (Smog) - ANSNot emitted directly into the air, it is created at ground level by a chemical reaction between NOx and HC in the presence of sunlight. Powertrain Control Module - ANSUse a microprocessor that processes info from engine inputs (sensors) and command outputs (actuators). Can store info for future access. Procedures that apply to the emissions sticker: - ANSDo not remove any stickers until the vehicle has passed inspection and is issued a new sticker. Wipe, dry, and clean the surface on which the sticker is being attached. Fill out the VIN, date, mileage, and sign the sticker using a permanent marking pen. Remove the protective slip-sheet Place proper monthly insert so that the month and year are visible to oncoming traffic.
Subject Vehicles - ANSVehicles of model year 1975 and newer, having a gross vehicle weight rating of 9,000 lbs or less. Gasoline powered buses that seat 15 or fewer and have a GVWR of 9, lbs or less are also required to undergo emissions testing. The DLC configuration and placement in the vehicle were also standardized by OBD-II regulations is from what 1990 act? - ANSFederal Clean Air Act There are two main forms that are presented to a customer following an inspection... - ANSPassing = one form Failing = two forms To become a CRT you must... - ANSHave a valid driver's license To deliver emissions waivers you must become a(n)... - ANSemissions Certified Repair Technician (CRT) True or False: 2 readiness monitors can be "Not Ready" with vehicles 1996 and newer. - ANSTrue True or False: Consists of a five-character alphanumeric code consisting of a single letter character followed by four numbers. - ANSTrue True or False: Only 1 readiness monitor for cars newer than 2001. - ANSTrue
Upon successful completion of the N-EIC program you will receive.. - ANSAn emissions inspection ID card from PennDOT that allows you to perform inspections on vehicles registered in the Northern Region counties only. Vehicle exemptions - ANSNew or current model year subject vehicles that have never been registered in PA or any other jurisdiction before the current owner, and have less than 5,000 miles on the odometer. Vehicles driven less than 5,000 miles in the previous 12 months that have been owned by the same person for a minimum of 1 year. What are the EGR valves used for? - ANSTo reduce NOx emissions on some engines. This is accomplished by allowing a metered amount of gas to be reintroduced into the combustion process to displace O2, which then reduces peak combustion temps. What are the numbers in "ASM5015"? - ANSThe vehicle will be tested at 50% of maximum load at a steady speed of 15 miles per hour. What are the rules when a customer challenges an I/M result? - ANSMust be made within 10 days of the date on which the vehicle failed. If vehicle passes, an emissions sticker must be issued for the vehicle and must not be charged.
What happens if a gas cap is not properly sealed? - ANSHarmful evaporative emissions are released into the atmosphere. What happens when there is not enough O2 in an engine? - ANSIt runs rich, meaning combustion forms more CO and less CO2. What if a gas cap is locked? - ANSVehicle must be rejected from testing. What if a vehicle has failed an emissions test, the owner has met the minimum emissions-related repair costs and the vehicle still fails the emissions test? - ANSThe owner may be eligible for a waiver. What if bar code scanning is not possible? - ANSThe equipment will require duplicate data entry to ensure the accurate collection of critical vehicle information. What if the vehicle stalls while waiting to be tested? - ANSRestart the vehicle and wait 30 seconds prior to starting the test. What is a gap cap test? - ANSTo see if the gas cap seals properly. What is a Tailpipe Emissions Test using Dynamometer (Loaded-Mode Testing) - ANSUses emissions equipment and a treadmill-like device which puts a load on the engine to simulate driving conditions at 15 miles per hour.
What is done during the pre-inspection safety evaluation? - ANSThe vehicle is checked to make sure you can safely perform an emissions inspection without causing risk or harm to yourself and/or causing damage to the vehicle. What is the cost limit? - ANS$150. What is the form given if a vehicle fails inspection? - ANSThe repair data form to complete and return upon re-inspection (should be completed regardless of who performs the repairs). What is the Northern-Emission Inspectors Certification program? - ANSLimited to performing the visual antitampering check and gas-cap test. What is the Positive Crankcase Ventilation System's purpose? - ANSTo control cylinder blow-by gases and HC emissions. What is the purpose of the Evaporative Emissions System? - ANSTo capture and store HC emissions produced by the evaporation fuel from the storage system. What is the tailpipe Emissions Test (No-Load Testing)? - ANSTwo speed idle test that measures the vehicles exhaust emissions at 2,500 revolutions per minute and at idle. (PASS, FAIL, or INVALID) -inspector may abort test at any time
When is proof of insurance required? - ANSNot for emissions but it is required for safety inspection. When should a waiver be offered? - ANSAny time a customer is eligible. If interested explain the next steps and whether or not your station can provide the waiver. Where is the DLC required to be? - ANSSomewhere between the left end of the driver's side of the instrument panel and 1 foot beyond the centerline on or below the instrument panel. Who can issue a waiver? - ANSA certified repair technician Why is oxygen (O2) not a reliable rich indicator? - ANSIt is low whenever the mixture is rich. Rich mixtures burn all available O2. Why is oxygen the best lean indicator? - ANSThe levels change during lean mixtures. Why would hydrocarbon be higher than the stoichiometric ratio? - ANSThe mixture is very rich or very lean. Normal combustion is 15:1 air/fuel ratio.
