these are added on gauges - of course.
The engine is running and they don't show any life?
They are both electrically operated - they will have a common ground circuit - check the wiring to the gauges.
Let me know if this helps
Many cars do this to discourage gas theft. If the car fuel gauge only shows 1/4 full, a potential thief may not bother to steal 2 or 3 gallons of gas. This is very normal.
If the gauge is stuck on full and you are sure the tank isn't full, you have a sensor sending wrong information to the dash gauge. Most cars now have a single fuel pump and sending unit that can be replaced by a mechanic.
the fuel sender in the tank is probably the problem, they do wear out quick on KIA some models.
the blue part covered in the pic is the sender unit for the fuel gauge.
use a old tooth brush not new as this is to harsh, and clean the strips on the sensor you can take this part off to clean all parts are just clipped on.
The check engine light will set a code, to read this code you must have the system scanned with a special tool. This is not a wiring GREMLIN, trust me. As far as the gas gauge goes you will need to pull the fuel tank out and replace the gas gauge fuel level sending unit.
Its likely a fuel system problem mabey a filter or pump issue .But what you need to do at this point is get the codes read if you have check engine or gauges lights on its the olny way to iscolate the problem it could be a number of sensors that could cause this aswell . Most auto parts stores will do this at no charge .This way your not going to waste a lot of money and time blindly replaceing compountes that may or may not be the problem so now is the time to think and find out what the problem could be and what it likely is Good luck
your fuel gauge may be reading inncorect so you may be real low on fuel which explain why it try to cut off around corners or you have an idle air valve problem have thecodes scanned to see what the malifunction is
This is a normal concern.
The instrument cluster uses 4 different operating modes to calculate the fuel level:
Anti-slosh (default mode) Key OFF fueling Key ON fueling Recovery After a fuel fill up, the time for the fuel gauge to move from empty (E) to full (F) ranges from 2 seconds to 55 minutes depending on which operating mode the fuel gauge is in.
The default fuel gauge mode is called the anti-slosh mode. To prevent fuel gauge changes from fuel slosh (gauge instability due to changes in fuel sender readings caused by fuel moving around in the tank), the fuel gauge takes approximately 55 minutes to go from empty (E) to full (F).
The key OFF fueling mode (2 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The key must be in the OFF position throughout the entire refueling of the vehicle. At least 15% of the vehicle's fuel capacity must be added to the fuel tank. The instrument cluster must receive a valid key ON fuel sender reading within 1 second of the key being put into the RUN position. The key ON sample readings are considered valid if the fuel sender reading is between 15 ohms ± 2 ohms and 160 ohms ± 4 ohms. If these conditions are not met, the fuel gauge stays in the anti-slosh mode, which results in a slow to read full (F) event.
The key ON fueling mode (approximately 90 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The transmission is in PARK (P). The key is in the RUN position. At least 15% of the vehicle's fuel capacity must be added to the fuel tank. In key ON fueling mode, a 30-second timer activates after the transmission is put into the PARK (P) position (automatic transmissions). When the 30-second time has elapsed and at least 15% of the vehicle's fuel capacity has been added, the fuel gauge response time is 90 seconds to read from empty (E) to full (F). When the transmission is shifted out of PARK (P), the fuel gauge strategy reverts to the anti-slosh mode. The key on refueling mode prevents slow to read full events from happening if the customer refuels the vehicle with the key in the RUN position.
Recovery mode is incorporated into the instrument cluster strategy to recover from a missing fuel level input during a refueling event. Missing fuel level inputs result from intermittent opens in the fuel sender or its circuits. Recovery mode (empty [E] to full [F] approximately 20 minutes) is initiated when the following 2 conditions are met:
The instrument cluster is in the anti-slosh (default) mode. The actual fuel level in the tank is greater than what is being displayed by the fuel gauge
