Performing Emissions Testing in Idaho
The Idaho DMV mails renewal reminders to vehicle owners in Ada and Canyon counties and sends the first notice a month before the test’s due date. The notice provides the test due date and testing information for the specific vehicle requiring testing and will provide a list of available local test sites Vehicle owners usually have until the end of the specified month to complete the test.
The Idaho DMV sends the second notice at the end of the end of that month reminding the owner to get their vehicle tested in a timely fashion. The owner will then have the next 35 days to get their vehicle tested, or The Idaho Department of Transportation will revoke their vehicle registration.
On-Board Diagnostic Tests – The Idaho DMV will administer an ODBII test on all motor vehicles made in the 1996 or newer model years in Ada and Canyon counties. The OBDII system installed in U.S. manufactured vehicles made in the 1996 and newer model years is a mechanical issue early-warning system. The system records the vehicle’s performance by administering a specific kind of test referred to as a “Monitor”. Monitors test a vehicle’s primary emissions components and subsystems. While the key is in the ignition and the engine is off, a test technician will make sure the vehicle’s DLC (Data Link Connector) works properly. Then, the test technician hooks an emissions diagnostic tool up to your vehicle’s DLC using a cable to allow the technician’s diagnostic tool to communicate with the vehicle’s OBD II system. The Idaho DMV test technician can check your vehicle’s engine and emissions systems, and see if any monitors state a “Not Ready” status. If there are too many monitors stating a “Not Ready” status, then the vehicle will not pass the test. The test personnel can complete the test in around 2 minutes.
Two-Speed Idle (TSI) Test – Idaho DMV personnel perform the TSI Test on vehicles made from 1991 through 1995. A Test technician measures to see how much hydrocarbons (HC), carbon monoxide (CO), and carbon dioxide (CO2) the vehicle emits from its tailpipe. Like the name implies, there are two speeds used in the TSI test. There’s Low RPM test (revolutions per minute) that measures a vehicle’s emissions at low RPM and the high RPM test measuring the vehicle’s emissions at a higher RPM.
Gas Cap Test – The Idaho DMV requires a Gas Cap Test. Vehicles older than 1995 will have their gas caps inspected visually to make sure they seal properly. Idaho registered vehicles made in the 1996 model year or later will have the ODBII system check their gas cap automatically.
When test personnel finishes administering an inspection the vehicle owner will receive a computer-generated Vehicle Inspection Report (VIR) containing the results of the emissions and fuel system tests.
Failed Smog Inspections – Next Steps
If a vehicle fails a smog check, they will receive a Vehicle Inspection Report (VIR) Diagnosing a vehicle to understand the reason it did not pass an emission inspection can be complicated. Vehicle owners are free to choose a technician or repair the vehicle themselves. However, diagnosing and repairing an emissions-related mechanical issue can be complex. The Idaho DMV strongly advises vehicle owners select a state-qualified emissions repair technician who has experience with emissions systems and who is able to diagnose and repair the vehicle correctly.
If a vehicle fails its initial vehicle emissions test, the vehicle owner has 30 days to get the vehicle retested for free after addressing the mechanical issues that caused the vehicle to fail its test. If your vehicle still does not pass the first retest, any additional retests will cost $11.00.
Low Income? Try Applying for an Idaho Hardship Waiver
If an Idaho vehicle owner is experiencing economic hardship, they may qualify for a Hardship waiver if their vehicle is unable to pass the test. The Idaho DMV reviews hardship waivers on a case-by-case basis. Hardship waivers are good for one year and vehicle owners can apply for two hardship waivers consecutively and must provide information about their current income and expenses. After that, if they are still experiencing difficult times financially, they may apply for a Repair waiver after they spend $200 to try to repair their vehicle after not passing an Idaho emissions test.
Moved to Idaho – Smog Check Requirements
Motor vehicle owners moving to Ada and Canyon counties, or the City of kuna with gasoline vehicles made after the 1981 model year and at least 5 years old must get a smog check. First, they must get their vehicle registered. Then, they will receive a vehicle testing notice from the Idaho Department of Motor Vehicles. The Idaho DMV suggests vehicle owners not get their vehicle tested until they receive their testing notice. The Idaho DMV mails notices to the address provided to them by the owner when they registered their vehicle.
Special Tips to Pass the Idaho Emissions Test
The State of Idaho suggests vehicle owners get their vehicle’s tested within 90 days after receiving their vehicle testing notice. Allow for extra time to get any needed repairs done before your registration expires. Also, if a vehicle owner plans to be out of town during the date when their registration expires, the extra 90 days will give them time to meet the deadline. Here are some tips to keep in mind to ensure passing an Idaho vehicle emissions test:
- Make sure the vehicle does not have its “Check Engine” light on; If it does, it will not pass the test. To fix, check to make the gas cap is on tight. If it is not, tighten it and drive around to see if the light goes off.
- Follow the vehicle’s recommended maintenance schedule. Many of the mechanical issues that cause vehicles to fail their tests can be addressed during a routine check-up
- If your vehicle is a make and model year when catalytic converters came standard on the vehicle, make sure your vehicle has one and is not malfunctioning; If it does not have one or it is not working, it will not pass the test
- Allow your vehicle to run for at least 10 minutes before it takes a test to ensure an accurate reading
- Research your vehicle manufacturer’s recalls Technical Service Bulletins (TSBs), and warranties before getting any repairs done. The cost of their repair may be covered by the manufacturer.
- If your vehicle’s On-Board Diagnostic (OBDII) system is showing trouble codes, make sure to get them fixed by a certified emissions mechanic. Do not just try to clear the codes.Test personnel will know and the vehicle will not pass inspection.
- If your vehicle is misfiring when it is idling, make sure to get this addressed before taking the test
- Check your vehicle’s gas cap and make sure it’s not broken. Keep the sealing surfaces in the cap clean so it can make a good seal
- If a vehicle’s battery is brand new, drive the vehicle for a couple of days before taking it to get an On-Board Diagnostics test so as to allow the OBD system to reset
- Make sure the vehicle’s oil is not dirty. Get the oil changed on a routine basis
- Maintain the recommended air pressure in your vehicle’s tires
- Inspect your vehicle’s hoses and belts for wear. Get them replaced if necessary
- Get any mechanical issues with your vehicle’s transmission address and fixed. Transmissions problems can affect your vehicle’s emissions and cause your vehicle to fail its test.
- If your motor vehicle’s emissions system has a mechanical issue, check your manufacturer’s warranty. Federal law states emissions systems on vehicles made in the 1995 and newer model years must have their emissions systems warrantied for two years or 24,000 miles.
- If the OBDII diagnostic system or catalytic converter on your vehicle made in the 1995 model year or newer has a mechanical issue, check your vehicle’s manufacturer’s warranty also. Federal regulation states these vehicles must have a warranty on their OBDII and catalytic converters for eight years or 80,000 miles.
