dodge ram 1500 oil pressure gauge dropping
Dodge ram 1500 oil pressure gauge dropping:
1. Internal malfunction of the instrument; If it is confirmed that the mechanical structure in the instrument is malfunctioning, it should be repaired to normal or the instrument assembly should be replaced;
2. Poor grounding of the circuit; The oil level sensor in the fuel tank works in conjunction with the oil float to convert the liquid level situation into an electrical signal and provide feedback to the instrument. Poor grounding in the circuit will prevent the transmission of electrical signals;
3. Deformation of float rod or oil tank; The deformation or damage of the float rod or fuel tank can cause the oil float to be in an inaccurate position, which cannot accurately represent the height of the fuel level in the fuel tank. Therefore, the oil float or fuel tank should be replaced or repaired;
4. The sliding resistance of the oil level sensor is stuck by foreign objects; The sliding resistance of the oil level sensor is stuck, the electrical signal value will not change, and the corresponding remaining oil quantity display will not change. The sliding resistance of the oil level sensor should be repaired to normal;
5. The matching between the oil level sensor and the instrument resistance value is not suitable. The first few reasons can be eliminated through simple testing and maintenance. The matching between the oil level sensor and the instrument resistance value is relatively complex, and once the matching design is improper, it will bring difficulties to maintenance.
The rapid decline of the oil gauge may not necessarily be due to oil leakage, but it is also possible that the oil level detection device in the fuel tank may malfunction. The oil level sensor in the fuel tank works in conjunction with the oil float, converting the liquid level situation into an electrical signal and feeding it back to the instrument. Through the system logic relationship, the instrument can assist in displaying the remaining fuel quantity, fuel consumption per 100 kilometers, instantaneous fuel consumption, and range wind signals, meeting the requirements of accuracy and timeliness. From the oil float of the oil pump to the wiring harness, ECU, instrument panel, etc. of the entire vehicle, there are many factors that affect the inaccurate indication of the oil gauge. There are generally three types of problems with inaccurate indication: high or low indication of the oil gauge, insufficient display of the oil gauge after filling up, and unstable or drifting up and down display of the oil gauge during driving.
