I am getting a P0455 code [evaporate emission leak detected (large leak)] on my 2004 Tiburon GT, along with a P0101 [Mass or volume air flow circuit range/performance] and P0102 [Mass or volume air flow circuit low input]. How can I test the individual sensors to see if one is faulty?
SOURCE: trouble code p0102
86-10056 , 74-10056 These are the two that i found.
This is the site i found them at.
Let me know if this helps.And thanks for the rating
SOURCE: 2000 hyundai sonata.. P0300, P0110 and P0102 codes..
Higher octane gas 93 with some good octane boost in the black can at autozone cost about 7 dollars or a bottle of 104 octane boost. Change the fuel filter. Probably only one coil pack is bad. The OBDII reader should tell you which one was a misfire.
SOURCE: Having the same problem the other guy described.
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.

IAT = Intake Air Temperature MAF = Mass Air Flow VAF = Volume Air Flow
The first thing I would do is to check at and around the air filter and air intake tube to make sure there are no connectors unplugged. If none are unplugged you will need to take it to a qualified repair facility to have the codes diagnosed. I would recommend finding a Napa Auto Care Center as they are held to a certain standard to be a certified facility.
