If it is a 1997 S10 4.3, with the engine running, remove the fuel pump relay, if the engines stops running, the oil pressure sensor is bad.
just to the right of the oil filter
it is the oil pressure sensor. Check your oil level, then test your oil pressure sensor.
You can pressure test with a gauge using sensor location
At upper rear drivers side of engine close to the distributor. In some cases removing the distributor makes access to the oil pressure sending unit easier.
Oil pressure is low, oil pressure sensor has failedOil pressure is low, oil pressure sensor has failed
They are easy to change. Here is an article on how to test them. Oil Pressure Sensor Testing 1. Test and verify the engine oil pressure. If no or insufficient pressure exits, oil pressure problem exits and gauge and sensor are operational, repair oil pressure problem. 2. Check the appropriate fuse before attempting any other diagnostics. 3. Unplug the sensor electrical hardness. 4. Using an ohmmeter, check continuity between the sensor terminals. 5. With the engine stopped, continuity should not exist. Ø The switch inside the oil pressure sensor opens at (6) psi or less of pressure. 6. With the engine running, continuity should exist. 7. If continuity does not exist as stated, the sensor is faulty.
No, a defective oil pressure sensor will not harm the engine as long as the oil pressure is what it should be. However, how do you know what the pressure is if the sensor is bad. Replace the sensor so that you can receive a warning if the oil pressure drops below what is optimum.
It does not have a oil pressure senser. That's way you can't find it. But it does have a oil sending unit back by the distributor, underneith it but to the right. It will be screewed into the back of the block, up on top.
The 1995 Nissan Pathfinder oil pressure sensor can be found next to the oil filter. The oil pressure sensor measures the oil pressure in the engine.
An oil pressure sensor socket.An oil pressure sensor socket.
Test with a mechanical gauge to accurately detemine oil pressure Could just be a defective oil pressure sensor
The oil pressure sensor sends a reading to the gauge so you can moniter the engine's oil pressure. No oil pressure means the engine is in big trouble.
