Oil is vital for engine operation – you can’t drive without it. Trying to run your car’s engine without oil would result in catastrophic damage. However, it’s just as important that the...
When you think about the number of sensors that your engine has, it seems like there is an endless amount of gauges that can be installed to monitor their readings. Some of...
Keeping an eye on your tire pressure is vital. Low tires wear poorly, and they can have a negative effect on your fuel economy. It also makes them more susceptible to...
The dimmer switch is probably a rheostat. It is possible that the switch is "open" in all positions. You could test the switch by simply bypassing it. If the switch turns out to be OK, the procedure is to use...
The sensor, gauge and wiring should be repaired if there is a reporting fault. The problem is if you leave it as is, you might not get adequate notice were actual overheating to occur at a future point. Overheating of...
The instrument panel has quite a few separate bulbs. You may have a circumstance where some of the bulbs are faulty and need to be replaced. If you are referring to intermittent operation though and/or gauge malfunctions, the cause could...
The sending unit in the fuel tank, the instrument gauge (receiving unit) and/or the interconnecting wiring has a fault. To determine where the fault lies, the circuit is simply traced and tested. If the sending unit in the tank turns...
The required gear is determined by the number of speedometer drive gear teeth in the transmission output, the rear end gear ratio (3.89, 3.08, 4.11, etc.), the tire diameter, and the number of RPM's the speedometer needs to "see" at...
Hello, thank you for writing in. The fuel pump is part of a unit called the fuel module. The module also houses a float that raises and lowers with the level of the fuel. That movement is then translated into...
Hello, thank you for writing in. The fuel pump itself has a level sensor that may have been damaged during the process. It is physical float that rises and lowers with the level of fuel in the tank, and then...
Hi there - first thing to check is fuses for these gauges. Did they "fail" at the same time? If so, a blown fuse is likely. If not the sensors for each (both of which are electronic) are suspect. Bad...
To gain access to the bulbs in the cluster, you must remove the cluster from the dash. You will need to remove the vents in the center of the dash, next to the cluster, in order to remove the screw...
The ignition switch is damaged and needs replaced. The contacts inside the ignition switch is are shorting out with itself. This is why the switch has to be in a specific position to release the shift interlock solenoid. If you...
Check the wiring harness from the gauge cluster to the speedometer and see if the gauge is working. If the gauge is not working, then the gauge cluster would need replaced. If the gauge is working, then there could be...
Hello, thank you for writing in. The speedometer and the fuel gauge run independently of each other up until they connect to the instrument cluster at the back of your dashboard. If the other gauges were failing as well, you...
There is no way to reset a fluctuating fuel gauge. The fuel gauge is bouncing or fluctuating for either the float in the fuel tank has a bad ground in the rheostat or the gauge cluster has a broke or...
With regard to the temperature gauge, the fault there could be due to the sending unit (which is the temperature sensor), the receiving unit (the dash gauge), the fuse or the circuit wiring. To resolve an issue such as that,...
Hi there - all manufacturers provide fuel gauge operation in the "Run" position. Almost all include fuel gauge function in the "Start" function - although some use that switch setting to test gauge operation momentarily (gauges swing full range, then...
Hi...the cost will vary quite a bit because the underlying fault could range from something as simple as a high resistance electrical connection in the fuel tank sending unit circuit to a dash gauge failure or a sending unit failure....
It's possible that your temperature gauge is operating erratically which would be an electrical problem (sending unit, gauge, wiring, etc.) rather than an actual overheating problem. The most common causes of overheating include low coolant level, a faulty thermostat, a...
For the fuel and temperature gauges check the wiring to the gauges and see if they are connected properly. For the speedometer, the needle maybe in the wrong position and reading incorrectly. When taking off the needles to the gauges,...
Hi there. The dashboard lights are burned out in the dash and the dimmer switch could be worn causing the lights to be weak. The gauges that seldom fail to work is most likely a loose wire in the dash...
