Question about 2001 Hyundai Elantra

How do you reset the monitors on a hyundai

I went through Aircare and failed the emissions test. I pulled the code and it was Code P0105. I researched and came to the conclusion it was the MAP Sensor. I erased the code and it came back instantly so I decided to put a new Map Sensor. Code erased and never came back. I had 5 flashing monitors so I was told to drive it than check it again. Checked than there was 3 after the Drive. EVAP, CAT, MIS. I cant get these to go off. Drove for 1 full day with highway and city drives. Got no where. What do I do. Is this because there are more problems or Have i just not completed the cycle.

You may have to drive 300 to 500 miles or more,on multiple days and at different speeds and make sure to include long deaccelerations with your foot off the gas to set the EVAP. Most areas allow 1 monitor "not reset" and still give a full pass.Check your area for allowed number of monitors. If the check engine light stays out,the monitors will eventually reset,but on a older Hyundai it takes time.

SOURCE: emissions test comes up not ready - can't pass inspection

Under the hood, there is a fuse block. I believe it is on the driver's side of your vehicle. Open that box, and pull the "ECU" fuse. Leave the fuse out for at least 5 minutes. Put the fuse back in, start the car, and let it idle for at least another 5 minutes. Do not drive the car, touch the gas, or even look at the gas pedal for these 5 minutes, as the ECU is remapping itself. This will properly reset the ecu and clear the codes. After this you may drive the car.

How many miles do i need to drive before my buick lesabre reset itself


Unfortunately it is not a certain amount of time or miles that the car needs to be driven.

There are several 'readiness monitors' that basically cover each emissions related system. For instance there is an EVAP monitor that checks the EVAP system and all of it's components under certain specific conditions (No VSS, TPS, O2 sensor, IAT, MAP, Fuel trim, Injector ciruit, EGR pintle position, ECT, or MAF sensor DTC codes set; Start up engine temp 40F-86F; gas tank between 15% and 85% full, Barometer above 75 kPa, system voltage 8V-16V).

So more information is needed as to what failed you the first time. What DTC code was triggered?

If the problem has been fixed right, the history codes will go away after 40 CONSECUTIVE drive cycles WITHOUT the problem re-occurring.

Good Luck.

2004 porsche cayenne i reset computer and now it will not start


Clearing Codes, clears all data, then all the emission
monitors have to run again, or you won't be excepted
to inspection

Clearing codes & data,has nothing to do with diagnosing
why you got the fault codes & fixing the problems

How would clearing a dash light help pass inspection?

Before you got down the street two houses, the light would
be back,the car has a failed system ,thus the light on the
dash after the motor is started.

You cleared all data,now a shop can't even work on it
You removed all vehicle history & codes

Flat bed it to a shop & they will make the repairs you neglected
to do, while trying to get hundred miles before the parameters
on a failed system went out of range & the dash light came back

Need to study OBD 2 Systems on the internet & leave the vehicle
work to the pros

P1105 p0105


105=MAP Circuit Malfunction (generic USA fed spec)
1105 = same as above but P1 means toyota factory code,
so what does this mean, it means the MAP monitor (tests) are failing.
what can make this fail; lots.
1: map bad.
2: map port clogged with crud, clean it, some cars have hose, it fell off or some one unpugged it, with key engine running.
3: wires to map bad.
4: engine vacuum real bad. a massive air (vacuum) leak. to the engine plenum and intake track.
reset it and see if it comes back
no engine power issues, as THE map RUN THE FUELING SHOW.

What is a P0105 check engine code on a 2004 Hyundai Sonata?


The code is telling you there is a problem with the MAP sensor which measures vacuum in the intake and outside air pressure.
The sensor needs to be tested and possibly replaced.

I have a 2002 Ford Taurus, and an engine sign showed up. However, I pulled out the code which is P0442. what is the problem, how much would that cost me and when do I need to fix it, can I wait for the...


P0442 code relating to the EVAP (Evaporative Emission System).a small emissions leak. also check the gas cap .Try cleaning the seals first and then try putting a little vaseline on the seals before getting a new gas cap. -------------
Code P0442-Evaporative emission control system. Canister Purge system failed the monitor test indicating a large leak (over 0.040”). Enabling conditions: Engine running after a 6 to 8 hour engine off period called a cold soak. The test runs when engine load is between 15 to 45% and inlet air temperature between 40 and 130°F. Blocking Action: This code can block the following monitors: Fuel Control, O2 monitor, Catalyst Monitor, misfire monitor. Testing: Check the purge hoses for leaks, leaking vapor management valve or loose gas cap.

This simply indicates that there was no flow from the evap system when the purge valve was energized. This could be cause of a few different reasons. First, check for leaks by visually looking at all evap lines for cranks rips or any tears. Basically, anywhere that fuel vapors can escape.
----------- Here is the test that will smoke the system for leaks with a smoke machine.

Evaporative Emission System Leak Test

SPECIAL TOOL(S)

CAUTION: The evaporative emission system must not be pressurized to more than 3.48 kPa (14 inches H2O)or damage to the evaporative emission system may occur.
  1. Connect the Evaporative Emission System Leak Tester to the evaporative emission test port.
  2. Close the canister vent solenoid.
  3. Pressurize the evaporative emission system to 3.48 kPa (14 inches H2O) .
  4. Monitor the system for two minutes . The system fails the leak test if the pressure falls below 2.0 kPa (8 inches H2O) .
  5. Repair any leaks as necessary.
  6. Repeat the leak test until the system remains above 2.0 kPa (8 inches H2O) after the two-minute test period.
---------- get it repaired ASAP because if you drive the car in same condition the emisson system can get damaged.and code will be p0445 ,now the code is p0442 its for leak in the emisson system. ---------------- This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya.

01 sonata gls v6...code po455, po442. what are these and how can I pass emissions test in arizona


If you have an EVAP leak, you will get the following codes:

1. P0442 evap emission control system leak (small).
2. P0455 evap emission control system leak (large).

If these codes come up, you need to trace the leak. The most common place for the systems to leak besides the gas cap is at the service port under the hood, the hoses at the purge solenoid, and the hoses around the fuel tank. Check all your EVAP hoses from under the hood , all the way back to the gas tank. You can repair a split hose easily. Buy some 14.5mm EVAP hose at the auto parts store. Just cut the split or cracked section out and attach the new hose.

I can only say that u must fix the code issue and light to pass state emission test, if u reset the light they will know, the system will tell the tester that the system is not ready, this will cause a fail.
