try changing your oil sending unit first there is no fuse for your oil gauge drive safe
Check your cylinder pressure with a compression gauge. The gauge will hook up to your spark plug openings.
It is possible a fuse blew. Check all fuses. If none blown take it to a garage. Check the instrument cluster voltage regulator.
The oil pressure gauge on your 2004 Chevy Express van 2500 may not be working due to a faulty oil pressure sending unit, which sends readings to the gauge. Other possible causes include a blown fuse, damaged wiring, or a malfunctioning gauge itself. Additionally, low oil levels or oil pump issues could affect pressure readings. It's best to diagnose the problem through a systematic check of these components.
In a 1995 Isuzu Rodeo pickup, the blinkers, gas gauge, and temperature gauge may stop working due to a blown fuse, faulty wiring, or a malfunctioning instrument cluster. A common issue is a blown fuse in the fuse box that controls these components. Additionally, a failed ground connection or a problem with the vehicle's main wiring harness can disrupt the electrical flow. It's advisable to check the fuses first, followed by inspecting wiring and connections.
It is possible that the temperature gauge has stopped working in a 1992 Tempo due to a blown fuse. It is also possible that the temperature gauge stopped working do to the temperature sensor in the engine having a short.
Possible causes of gauge not working. Faulty gauge Blown fuse. Open circuit in wiring to the gauge. Temprature transmitter in engine faulty. ( most probably the actual fault ) Lack of coolant in the engine.
With the thermostat.
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
The fuel pressure for a 2001 Isuzu Rodeo with a 2.2L engine typically ranges from 40 to 50 psi (pounds per square inch) when the engine is running. It's important to check this pressure using a fuel pressure gauge for proper diagnostics and maintenance. Always refer to the vehicle's service manual for the most accurate specifications and procedures.
A compound gauge is a pressure gauge that displays both negative and positive gauge pressure measurements. Gauge pressure is a measurement of pressure relative to ambient pressure. For example, if ambient pressure was 14.7 PSI and you were to measure absolute vaccum using a compound gauge, the gauge would indicate -14.7 PSI.
To calculate gauge pressure in a system, subtract the atmospheric pressure from the absolute pressure within the system. Gauge pressure Absolute pressure - Atmospheric pressure.
To convert gauge pressure to absolute pressure, add the atmospheric pressure to the gauge pressure reading. This will give you the total pressure, including the pressure exerted by the atmosphere.
