Guage Malfunction

A loose ground wire connected to the tank sender causes the majority of gauge malfunctions.

If turning on the ignition does not cause the dash gauge needle to move when the tank has gas, then an interruption exists that is keeping the battery current from reaching the gas gauge. A defective gas gauge or tank sender will keep the dash gauge needle from moving in either direction when turning the ignition on or off.

A lower than accurate gas gauge reading suggests a connection issue exists between the gas gauge and tank sender, while a higher than accurate gas gauge reading suggests a wiring malfunction in the tank sender unit.

A defective gas gauge unit will cause the dash gauge to read empty regardless of the amount of gas in the tank.

Helpful Repair Tips

Check to ensure that all wires are tight and that connections are clean of any dirt or rust. This will eliminate or help narrow down the cause of the gauge malfunction.

If malfunction persists, contact your local mechanic to schedule maintenance.

Kia Sorento repair manuals are available for purchase online for as little as $10 dollars each (as of 2010).
