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

REPAIR PROCEDURE:

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.

So whats your question???

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".
