gauges

Hello, thanks for writing in about your Jeep Cherokee. The coolant temperature sensor for the gauge on your Cherokee should be on the back of the driver's side cylinder head. If you need some assistance with this, consider YourMechanic, as...

The gauges on your dash are there to provide you with critical information while the vehicle is in operation. While some of them only work if the car is moving (your speedometer and tachometer, for instance), the engine coolant temperature...

Check to see if the cooling fan clutch (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-fan-clutch) is fully engaging when the engine is heating up. You can test this by putting a tissue in front of the radiator or condenser to see if the fan flow is...

The normal opening temperature of the thermostat is between 85c and 102c. Your car is running in the middle and this is good. You should not be overheating as this is the normal operating range for your engine. If you...

Hi there. The issue is the thermostat. It is sticking about half way and not opening all the way up or it has a lot of calcium buildup. I recommend replacing the thermostat (https://www.yourmechanic.com/services/thermostat-replacement) and flushing the coolant out (https://www.yourmechanic.com/services/cooling-system-flush)...

With most any other vehicle, your diagnosis would be dead on, congratulations! In your case, the problem is most likely the thermostat. With this Audi engine, the Audi engineers were more clever, there is only a single coolant temperature sensor,...

Hi there. Excessive oil pressure registering on the gauge can be due to a few different possible problems and would need additional testing to isolate the problem. The most common cause of the problem is the oil pressure sending unit...

Hello. If only your tachometer and speedometer aren't working, the problem is probably with the instrument cluster itself. This is because these two gauges use completely different inputs. The speedometer gets its signal from the vehicle speed sensor (VSS), whereas...

You're correct, the problem could be with the wiring. However, the improper reading may also be due to a faulty sending unit or gauge. A technician well versed in electronic troubleshooting, such as one form YourMechanic, will be able to...

This problem may be due to a fuel gauge sender malfunction, which is fairly common, or it could stem from the motors behind the instrument cluster that move the gauge needles. The fuel gauge sender is typically found in the...

The gauges on your dash are there to provide you with critical information while the vehicle is in operation. While some of them only work if the car is moving (your speedometer and tachometer, for instance), the engine coolant temperature...

Are and of the gauges not acting like they normally do? On your vehicle a common failure is of the oil pressure sending unit. When this happens your gauge will display zero oil pressure and cause the check gauges light...

As you may know, your car has a fuel sending unit (https://www.yourmechanic.com/services/fuel-gauge-sender-replacement) inside the fuel tank that operates on a float system. This monitors the level of the fuel in the tank using a float that relays these levels back...

You would need to check the temperature sender unit to see if it got coolant in the connector or wire got shorted somehow. Disconnect the sensor and see if the gauge acts differently. If it does then replace the sensor...

Hello. If the coolant temperature gauge is constantly fluctuating then the most common cause of this is a bad thermostat. If the thermostat is sticking or not opening and closing right then this will occur. It can also be a...

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...

It really depends on if the problems are related or not, they might share the same ground but they get different signals from their respective sensors. It could be as easy as changing the entire dash gauges or it could...

Some older vehicles do not have a baffle on the fuel pump, to prevent rapid changes in fuel level when turning. This may be normal for this vehicle. Fuel milage can be affected by several items like failing sensors, mechanical...

Hello, the operation of the fuel gauge is like this. The fuel level sensor receives a steady voltage input, and as the level changes the voltage output of the fuel level sensor change. The fuel gauge in the dash receives...

The fuel gauge on the dashboard receives a signal from sensors in the gas tank. Some models of your vehicle have multiple sensors and both have to be working properly for an accurate fuel level. An experienced technician, such as...
