Question about Hyundai Accent

1 Answer

My 2000 Hyndai Accent would only accept fuel at a very slow rate. If you tried to hold the fuel nozzle at half way, the fuel pump would click off as if the vehicle was full. it would accept maybe 10-20 cents at a time. Therefore, it would take a long time to get even $5.00 dollars into the tank. Some one I know stuck something down into the tank, after removing the filler neck from it, and was able to push something that was lodged out. The vehicle is now accepting fuel but now smells of fuel all the time and the check engine light was and is still on. Can anyone help with this problem? p1402 and p1403 are the current codes coming up.

Power Stage (DMTL Motor)

Power Stage (DMTL Valve)

The 2000 model year Accent adopts a new "pressurized" leak check system capable of detecting a 0.020" (0.5 mm) diameter leak (previous Hyundai systems detect a 0.040" [1mm] diameter leak using engine vacuum). The new system uses a Diagnostic Module for Tank Leakage (DM-TL) to close and pressurize the fuel evaporative emissions system. The DM-TL replaces the fuel tank pressure sensor and the canister close valve from previous systems. Other significant changes were made to the system logic, including several new diagnostic trouble codes. The diagnostic module (refer to photos on page 3) consists of a motorized air pump, a solenoid shuttle (sealing) valve, and a 0.020" (0.5 mm) diameter reference orifice. After the vehicle meets the self check requirements (see Self Check Requirements When Not Using The Hi-Scan Pro Section), the DM-TL activates to check for system leakage. The air pump and shuttle valve work on the command of the ECM. Motorized Air Pump - the pump pressurizes the evaporative emissions system producing a current draw that the ECM reads to determine pass/fail conditions. When the pump is switched 'ON', current draw is typically 17 - 36 mA. Solenoid Shuttle Valve - the shuttle (sealing) valve has two sealing sides (front and rear) that provide two functions: A. When the valve is "OFF" (no voltage aplied to valve), the front sealing surface directs air from the air pump (if it is "ON") through the 0.020" (0.5mm) diameter reference orifice. The rear sealing surface is openand provides an open path between the charcoal canister and freshair. B. When the valve is "ON" the front sealing surface is open directing air from the air pump into the evaporative emissions system. The rear sealing surface is closed, sealing off the evaporative emission system for the leak check. 0.020" (0.5 mm) Diameter Reference Orifice - the built-in reference orifice provides the ECM the current draw of the air pump motor for current ambient conditions (temperature,humidity etc.) to determine pass/fail conditions duringthe system leak check. My 2000 Hyndai Accent would only accept fuel at a - 1fc9b8a.gif P1402 DM-TL Circuit Continuity Check (Pump Motor) - short circuited, or disconnected. P1403 DM-TL Circuit Continuity Check (Shuttle Valve) - short circuited, or disconnected. IMPORTANT NOTE!.. you have a fuel leak now. These codes are NOT a direct cause of that leak... they are a result.

2c775b4.gif It is highly recommended to use the Hyundai Hi-Scan Pro to activate the evaporative emission self check. Using theHi-Scan Pro will save time and provide more consistent results. Moreover, "road testing" of the evaporative emission system in a 2000 MY Accent is not practical (requiring up to a 4day time frame to verify a repair). The leakage self check can be found on the main menu after selecting Model and Year of the vehicle. For the 2000 Accent, the menu item is labeled "DM-TL Test". To familarize yourself with the operation of the self check, remove the fuel cap of a 2000 Accent that is operating properly and activate the self check (follow the instructions on the Hi-ScanPro screen). With the fuel cap removed, Diagnostic Trouble CodeP0455, or P0442 will register in the ECM memory after the test is finished. (NOTE: The "Check Engine" light will not illuminate because the self check has only been run once. However, the code will be stored in the ECM memory. The "Check Engine" light will illuminate if the ignition key is switched to off, and the main power relay shuts off, and then the self check is performeda second time.). Erase the code when finished, and securely replace the fuel cap. If no code appears, turn the ignition key to off until the main power relay shuts off and retry the process. If no code appears at this point, call the Hyundai Tech Line. 7. SYSTEM SELF CHECK REQUIREMENTS (WHEN NOT ACTIVATED BY HI-SCAN PRO) For verification of a repair, it is highly recommended to use the Hi-Scan Pro to activate the self check. The importance of using the Hi-Scan Pro can't be over-emphasized because of the different self check requirements for the 2000 Accent. Use of the Hi-Scan Pro bypasses all of the self check criteria described below, allowing the technician to perform the self check at anytime, regardless of the conditions. Under normal operating conditions, the leak check occurs almost immediately after the vehicle is shut off and items 1-8 have been achieved. The ECM"s prerequisite for this check areas follows:

  1. Vehicle must have cooled down (not driven) a minimum of 5 hours (typically overnight).
  2. Vehicle must have been driven 20 minutes or more.
  3. Engine "off" and ignition key "off".
  4. Vehicle"s fuel level must be between 15% - 85% full.
  5. Ambient temperature between 39ðF - 95ðF (4ð - 35ðC).
  6. Altitude lower than 8250 feet (2500 m).
  7. Battery Voltage between 11.5 - 14.5 volts.
  8. Activates every other time (every second time) after conditions 1-7 are met.
NOTE The leak check will occur regardless of fuel level when conditions 1-7 are met, if the ECM has stored a DTC for the fuellevel sensor (P0460; Fuel Level Sensor Rationality Check).

I have a 2000 Hyundai Accent. Whenever I go to fill up my gas tank, the pump clicks every minute or so (like it does when your tank is full). Is my float stuck at full? How do I get it unstuck?

Kaylie, try letting off on the gas pump trigger a little and pull nozzle out of fill port approx. 1/2", this will normally slow the flow rate of pump down and let air behind gas and stop shutting off. Some pumps are just set to pump too fast/ too much volume. If this does not work for you, have a Tech. check and see if there is some other restriction,plugged vent or problem with the vapor canister. Check the attached links,instruction and guides, Good luck

When putting gas in my 2004 Kia amanit the fuel nozzle kicks off. How do I locate and fix the problem

HI Bridgette,

Due to the different shapes of fuel tank filler necks in cars & trucks, it may be necessary to vary one or more things to allow fuel to flow uninterrupted until the tank is really full.

The main problem can come from the new "vapor recovery" gasoline pumps. These pumps and hoses actually recover gasoline fumes from your tank as the liquid gasoline displaces the air / fumes in the tank is it is being filled. If gasoline flow is started at full blast, it can splash back slightly, causing liquid to be pulled back by the pump - so it shuts off. So, start with a slow rate of filling and gradually increase flow rate to maximum over 5 to 10 seconds. If it still shuts off, try some of the suggestions below.

First, don't fill at maximum flow rate from the pump - that is, don't set the nozzle for wide open. Select one of the other "latches" on the handle instead of the fastest flow and let the tank fill entirely at this rate.

Second, you should experiment a bit with the length of nozzle that you push into the tank's filler neck. If you push it in too far or too little, the pump nozzle can do what you're describing.

Third, try twisting the nozzle slightly so that it doesn't hang straight downward - a little to the left or right may provide a solution.

Lastly, try a different gas station. Their pumps may not be so picky with your tank's filler neck.

Good luck!

The 2000 chevrolet impala won't fill gas properly. It takes a long time and clicks off the gas pump.

This happens in my buick. Try pulling the nozzle out about half way (remember to hold it) or try moving it side to side. In my car, i have to hold it all the way to the right so it shoots down in to the left. It sucks having to hold it, but its better that doing that "Pump Click Pump Click" BS.

Where is the fuel filter on a 2000 hyndai elantra

If it's anything like the 2000 Hyundai Accent (which it probably is) it is mounted on top of the gas tank. First make sure you have a tank that is less than half full (8lbs per gallon), then jack up the car and place jackstands in a secure place. Then place a jack and 2x4 under the tank. Remove the 2 straps and slowly lower the fuel tank, it's most likely on the passenger side on top of the tank.

Where is the fuel filter located in 2000 hyndai accent sedan?

The fuel filter is located under the rear seat.
  1. Reduce the internal pressure of the fuel lines and hoses by completing the following operations:
    • After removing the rear seat cushion, disconnect the fuel pump harness.
    • Start the engine. Allow it to stop by itself, then turn the ignition switch OFF .
    • Disconnect the battery negative (-) terminal.
    • Connect the fuel pump harness connector.

  2. Remove the eye bolts while holding the fuel filter nuts securely.

How do I unjam a rear passenger seat belt from a hyndai accent 2000

i strongly recommend you take your vehicle to your vehicle's local dealer and have the belt removed from the door and then inspect the belt for damage. A damaged seat belt might break when you need it most. Seatbelts and safety are the most important thing!

Happy to help
Have a nice day!
