Sounds like your filter needs to be cleaned: DE < BUY THE FITER CLEANER> SAND: GET NEW SAND CARTRIDGE: BUY THE FILTER CLEANER
The cleaner the filter is the lower the initial back pressure is going to be, if you have a valve between the filter and the pool return turn, shut of the flow of water for just a moment. if the impeller is working properly the back pressure gauge should suddenly start to read high. Other reasons for low back pressure may be that the seals inside the unit are not properly settled.
To ensure that your Hayward Micro Star Clear C225 filter is not reaching maximum pressure without a pressure gauge, you can monitor the flow rate and the cleanliness of the filter. Regularly check the water flow returning to the pool; a significant decrease in flow might indicate that the filter is becoming clogged. Additionally, perform routine maintenance by cleaning or replacing the filter media as needed, typically every few weeks or based on usage, to maintain optimal performance.
The pressure gauge on a Hayward S240 sand filter should typically read between 8 to 12 psi when the system is running normally. If the pressure rises significantly above this range, it may indicate that the filter is dirty and needs to be backwashed or cleaned. Conversely, a reading below this range may suggest a problem with the pump or a leak in the system. Regular monitoring of the gauge helps maintain optimal filtration performance.
To achieve strong pressure from a Hayward Perflex filter, first ensure that the filter is clean and free of debris by backwashing or cleaning the filter element as needed. Check that the pump is operating efficiently and that there are no leaks or blockages in the plumbing. Additionally, confirm that the correct amount of filter media is used and that the multiport valve is set to the appropriate position for filtering. Regular maintenance and monitoring of the pressure gauge will help maintain optimal performance.

An inoperative temperature gauge will not alter how an engine runs, but the operator will not know if the water temperature has risen above normal without a properly working guage.
First check the fuse for the 2003 Cavalier gauge. Next check the fuel sending unit in the fuel tank to insure that its working properly. Check the gauge next, then the wiring for the system. One of these units is causing your gauge to not work.
The top of a Hayward pool filter typically features a round or slightly domed design, often with a lid that can be easily removed for maintenance. It usually includes a pressure gauge to monitor the filter's performance and may have a multiport valve for controlling water flow and filter functions. The exterior is often made of durable plastic or fiberglass, designed to withstand outdoor conditions. There may also be a label or markings indicating the model and operational instructions.
Check your vehicle speed sensor. It controls your RPM's and your Speedometer. Hope this helps.
it is likely your fuel gauge is not working properly
