Question about Hyundai Cars & Trucks
2004 Hyundai Accent, failed safety inspection exhaust system leaks on the flex pipe. So, my question is can I use sealant, or tape to fix it so I pass inspection. It hasn't effected power of the car.

SOURCE: small evap leak
The evap leak is short for EVARORATIVE EMISSIONS SYSTEM, NOT AC EVAPORATOR, AC leaks do not cause the truck to fail emission, most likely the problem is a defective gas cap. Also the code you give (P0244) is a watse gate code, please provide the correct code.

hi from uk location of fuel safety shut off valve/switch on uk r/h drive accents is on the engine bay bulkhead in front of drivers side it is a square box with red rubber top press button may be on opposite side on l/h drives ? if activated? just press button till click ? to reset these normally only cut off on impact ? to stop elec fuel pump continuing delivering if involved in an R.T.A fire prevention

O2 not ready could be that the sensor is not warm enough due to the engine not being warmed up, or the sensor's heating element not working. This would cause a richer air/fuel mixture showing a catalyst problem. If you are over 60,000 miles or so, it could be the O2 sensor, but you need to have it diagnosed before replacing the wrong part. Possibilities include a bad, fouled, or damaged sensor. The wiring could also be damaged by contact with road debris or the exhaust pipe. Leaking injectors can also produce a very rich mixture, but a good O2 sensor should be able to detect this and set a code. High oxygen content in the exhaust means unburned fuel because in combustion, the oxygen is used up. Good combustion leaves low oxygen in the exhaust. The oxygen sensor measures the oxygen content and lets the processor adjust the air/fuel ratio according to this reading and that of other sensors such as throttle position, mass air flow, coolant temperature, and ambient air temperature. The codes received at the inspection are basically the same ones used to diagnose the problem. There are dealer specific codes also used for repair. I really hope this helps. Please let me know if you need any more help. Thanks

First of all, these codes are what are called "Powertrain Trouble Codes' (that's what the "P" means P=Powertrain). TCM Request (Transmission Control Module = TCM). The request was to turn on the 'Check Engine" light.
P0720 - output speed sensor circuit malfunction
P0715 - Input speed sensor (turbin speed) circuit malfunction
P0442 - Evaporative Emission System Leak (Small Leak)
P0455 - Evaporative Emission System Leak (Large Leak)
Check fuel filler cap problems - for Evap Emiss leaks
Replace the pulse generators & have the trans fluid replaced/flushed.
The Main Catalyst System Efficiency Bank 1 Is P0420, not P0442
If you had P0420 code, the catalytic converter is shot... and that's an expensive component.
