water temp/oil pressure gauge not working in 97 jeep wrangler

• 2023-03-30

If the 97 jeep wrangler water temp gauge does not work, it is generally recommended to check whether the water temperature sensor is damaged. This should be caused by a broken water temperature sensor. The oil gauge doesn't move, there are probably three problems. First: The gasoline pump is malfunctioning. Second: Circuit failure (including insurance). Third: The car's oil gauge is damaged. The temperature sensor is faulty, indicating that the water temperature gauge display does not match the actual water temperature. If the fuel gauge doesn't move, you can replace the gasoline pump. If the gasoline pump has been replaced and still doesn't work, it's a problem with the meter. During a prolonged traffic jam, the water temperature has exceeded 100 degrees Celsius, but the sensor cannot tell the trip computer the information. The fan does not work, causing the antifreeze to boil. However, during normal driving, due to the large amount of wind cooling and air intake, the fan is replaced for operation, so it can be driven normally.

If the 97 jeep wrangler oil pressure gauge does not work, first check whether there is oil in the oil pan. If there is no oil, it indicates that the oil pipe is broken, cracked, or the oil drain plug of the oil pan is loose, resulting in oil leakage. Secondly, check whether the oil pressure gauge and sensing plug are damaged. First, the fault was checked using conventional methods. At this point, remove the wire from the sensor of the oil pressure gauge, connect one end of the test lamp to the sensor wire, and connect the other end to ground. After the instrument power is turned on, the oil pressure gauge displays startup, but it is very slow. When disconnected, the pointer is zero. Repeat the test several times, and the results are all the same. Pull out the oil dipstick of the diesel engine and observe the oil level and quality in the oil pan. It is found that the oil level is normal and the oil quality is reliable Therefore, it is judged that the fault may be a problem with the oil sensor or oil pressure gauge In order to determine the location of the fault, another sensor of the original model that was in normal use was removed to replace the test. It was found that the oil pressure gauge still did not work. Subsequently, the sensor was removed from the diesel engine, leaving the orifice where the sensor was installed open, and the diesel engine was started to observe the engine oil injection.
