How does the oil pressure sensor work on a Chevy?
How does the oil pressure sensor work on a Chevy?
This sensor measures the pressure of the engine oil and relays this data to the PCM. When the PCM detects low oil pressure it illuminates the oil pressure light. As time passes, the oil pressure sensor may develop an oil leak or begin providing the PCM with inaccurate pressure information, necessitating its replacement.
Why is my oil pressure sensor not working?
When the PCM detects low oil pressure it illuminates the oil pressure light. As time passes, the oil pressure sensor may develop an oil leak or begin providing the PCM with inaccurate pressure information, necessitating its replacement. New oil pressure sensors can be purchased from automotive parts stores and Chevrolet dealerships.
How to test the oil pressure sensor on a 4.3L engine?
Turn off the engine and disconnect the oil pressure sensor’s electrical connector and remove the sensor from the engine using a 1-inch box-end wrench. [Install an oil pressure gauge] (https://itstillruns.com/install-oil-pressure-gauge-6547614.html) into the oil pressure sensor hole on the engine block. Start the engine and watch the gauge.
What should the oil pressure be at 1000 rpm?
It should read at least 6 psi at 1000 rpm. If the oil pressure meets or exceeds this specification but the oil pressure light is on, then the sensor is faulty and must be replaced. Oil pressure gauges are designed to measure the oil pressure inside an engine.

What to do if your oil pressure sensor is faulty?
Clean any residual oil off of the sensor and start the engine. Watch the sensor to see if any oil leaks out. If oil seeps out of the sensor at any point, then the sensor is faulty. Turn off the engine and disconnect the oil pressure sensor’s electrical connector and remove the sensor from the engine using a 1-inch box-end wrench.
