2005 tahoe oil pressure sensor replacement
The oil pressure sensor can monitor the oil pressure status of the vehicle in real time. When the oil pressure is insufficient, the pressure sensor will transmit electrical signals to the ECU, which will light the fault light to inform the driver. Then how should we judge whether the oil pressure sensor is broken? Now let's answer this question for you.
1. After the vehicle is started, the oil pressure indicator light comes on. At this time, we should immediately shut down the engine and send it for repair as soon as possible;
2. The dynamic attenuation is obvious. If the pressure sensor is damaged, it is likely that the engine lubrication will not be in place, so the increase of friction in the cylinder will reduce the power;
3. The special computer can read the fault code "P01CA", which indicates that the oil pressure sensor voltage is higher than the upper limit. The oil pressure sensor does not need to be replaced regularly, and only needs to be replaced in case of failure. Performance of broken oil pressure sensor: the oil pressure indicator lights up after the vehicle is started; Dynamic attenuation is obvious; Read the fault code P01CA with a special computer, indicating that the oil pressure sensor voltage is higher than the upper limit. The oil pressure sensor is an important device to detect the oil pressure of the vehicle engine, And the detected data can help control the normal operation of the engine. The electronic oil pressure sensor consists of a thick film pressure sensor chip, a signal processing circuit, a housing, a fixed circuit board device and 2 leads (signal line and alarm line). The signal processing circuit consists of power supply circuit, sensor compensation circuit, zero adjustment circuit, voltage amplification circuit, current amplification circuit, filter circuit and alarm circuit.
How to solve the fault of oil pressure sensor? The oil pressure sensor is designed to prevent the engine oil from being too low, so if the oil pressure is found to be low, the sensor expert network reminds everyone that the engine needs to be stopped for inspection. If it is not repaired, the engine will be damaged!
