Hi,


There are 2 sensors on the engine that sent a signal to the computer and speedometer and tachometer. When one of these goes bad it can make the speedometer and tachometer go all over the place and also just stop working. This can also cause all types of engine running problems because the information is sent to the PCM will be incorrect all so. The units are easy to replace once you find them, it seems that they are located in different areas of the engine with each year the vehicle was put out. Your local dealer should be able to tell you the location of each sending unit.

2004 kia optima stalled while driving down the road after 15min or so it willstart backup


if check engine light comes on, get it scanned. you can get it scanned at auto-zone for free. as long as the check engine light is on. but it sounds like a bad crank sensor! that is the way the sensor is. it will die out and about 15 or 20 minutes it will restart. get it scanned. good-day! it controls the timing of engine.

The speed sensor is what sends a signal to the speedometer. It's located on the transmission housing, usually at the output shaft. Have the engine codes read with a scanner to make sure that's what's causing the check engine light to illuminate.

How do you reset the check engine light on a 2004 kia optima code is p0350 coil or looseconnection


YOu need an OBDII can scanner. Your local autozone, advanced, or oreilly auto parts can get coes adn clear them. They will reappear within a 70 mile drive cycle. I would check all connections and think about replacing coil.
