Question about Hyundai Sonata

1 Answer

Looking for Hyundai Sonata TSB #99-30-002 Diagnostic Procedure: Hard-To-Fill Fuel Tank. All versions I have found did not contain any diagrams or graphics.

No OBD codes. Have isolated evap canister from rest of system by removing 1/2" hose that goes to Neck (liquid-vapor separator), made no difference in gassing up. Also, checked Evap Canister manually, no charcoal pellets in any hoses, was able to blow air with little back pressure through canister, close valve and air filter. Suspect, fuel cut valve or vent valve. Not sure of other system components.

Actually I had that problem, its a faulty fuel sensor, and can be replaced under warranty. at first they had me unplug a fuse while the car was running then shut it off and plug it in then start the car. did that for 2 more fillups b4 they finally replace the faulty sensor.

SOURCE: Unable to fill the gas tank when the car is sitting level

These fuel tanks are designed weird, they have a hump in the middle for the driveshaft. Most of the time I have found if the pump clicks off early it is the fuel vent valve, which is located on the rh side, but a fuel cut valve could do the same thing. If the pump clicks off early (sometimes after 1 gal), make sure the canister filter isn't clogged and replaced the vent valve.

P0705 Transmission Range Sensor Circuit Malfunction

You haven't revealed the Hyundai Model, nor Year??

Here's info from the latest technical service bulletin:

This TSB supersedes TSB 03-40-013 to add repair information (Steps 2~3).


An improperly adjusted or improperly operating range switch may result in the following conditions:

• Diagnostic trouble codes:

• P0705 - Range switch signal problem

• P0707 - Range switch - open circuit

• P0708 - Range switch - short circuit or multiple inputs

• Malfunction Indicator Light (MIL) illuminated

• Impossible engine start in "P" or "N"

This TSB provides information concerning the proper adjustment and diagnosis of the transaxle range switch.


1. Attach a GDS and check for DTC in both the "Engine" and "Automatic Transaxle" menus. Go to Step 2 for 2000~02 Accent or Step 3 for 2006~ Sonata. For other vehicles, go to Step 4.

2. For 2000~2002 Accent: Check according to TSB 03-40-001. Go to Step 4.

3. For 2006~ Sonata, follow steps a,b,c below, then go to Step 4.

a. Check the rear combination lamp ground bolts for tightness and good electrical contact (refer to applicable ETM, "Tail, Parking & License Lamps" section). Go to Step b.Page 2 of 6

b. For 2006~ Sonata: Remove the center console cover and check for contamination on the M40 connector to the sports mode switch. If so, clean and repair the connector as necessary. Go to step c below.

c. For 2006~07 Sonata: Remove the front pillar cover and verify the harness is properly routed near the clip. Repair the harness as necessary. Go to Step 4.

4. Attach a GDS and select vehicle, "A/T" menu, "Current Data" and "Shift Lever Switch".

5. Move the shift lever and confirm the GDS reads the gear shift position as shown below. If so, the harness currently does not have an open or short circuit between. the PCM/TCM and range switch.

Hope this helps.

Hi there. I can solve this dangerous problem you are having. You would loose acceleration at lights and intersections, the engine will shake and revs can go crazy. The issue is the MAF (mass air flow) sensor. It was recalled in 2001 as a safety problem as people died driving this model of sonata. If you connect your comp up to a diagnostic machine you will find its the MAF the problem is a problem that is hard to ctah on a diagnostic machine though as it comes and goes. You will need to replace the MAF ASAP as you can die from this fault and hyundai will not care due to the age of this car.

My dealer told me that if you fill up beyond the first "click" of the gas pump it will mess up the sensor in the gas tank. It might fix it's self eventually, but can be avoided if you anly fill the tank up to that "click".
