Why would your oil pressure sensor register no pressure if the car is running fine?

Many sending units do not have continuity below 6-7psi. This would cause the gauge to read nothing and indicate a base engine problem. Some type of engine noise would be associated with this concern (ie. ticking, rattling). The sending unit or wire to the gauge could be open. This would be an electrical problem and have nothing to do with the engine. Along that same line would be a defective gauge.

86 firebird 2.8 would a map sensor keep a engine from running?
yes the map sensor will keep the car from running.map stands for manifold air pressure and if the ecu cant get a reading it will not start and run.

What possible reasons would a 1997 ford expedition lose oil pressure after a few miles?
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.
How do you determine if a 1994 ram 3500 has two or four wheel abs?
A 4 wheel abs would have sensor wires running to the front wheel bearings.A 4 wheel abs would have sensor wires running to the front wheel bearings.
Why does gasoline come out of a moffler?
Your Engine is running to rich. Depending on the year and type of vehicle,would make troubleshooting easier. Bad float in carb, leaking injector, fuel pressure regulator, bad 02 sensor, mass sensor and more. Is running and coming out, or cranking not starting and coming out, all makes a difference to troubleshoot.
Why would an Infiniti QX4 just stop running?
Mass Air Flow Sensor.
Would the crankshaft sensor keep the motor from running and would it stop the valves from moving on your 1998 Chevy Malibu?
It could keep the engine from running, but not the valves from moving.
Would an oil pressure sensor cause an 3406-E to crank but not start?
No, it has nothing to do with that.
Would a mass air flow sensor on a 99 cadillac deville stop the engine from running?
A bad Mass airflow sensor - on any GM vehicle that is equipped with one - will DEFINITELY stop the engine from running.
Where is the oil pressure sensor located on a 4.3 engine?
There are many 4.3 liter engines. In order to know where the oil pressure sensor is located in a 4.3 liter engine, the brand would need to be known.
