No there is not a sensor to keep it from starting if the oil is low
A defective O2 sensor will not prevent the engine from starting. The engine will start and run albeit not as it should.
Lock up, No but a bad crank sensor will prevent the engine from starting.
Yes. Cam sensor will determine the rotation of the camshaft, and if it does not sense it 'turning' the sensor will not allow the engine to start (it protects damaging the engine). Faulty camshaft or crankshaft sensors will stall engine and prevent restart until replaced.
P0340 is a failure in the cam shaft sensor circuit. That can prevent the engine from running.P0340 is a failure in the cam shaft sensor circuit. That can prevent the engine from running.
The camshaft position sensor on a 4.6 liter engine is positioned on the side of the motor on the front of the cylinder head. A 4.6 liter engine has a camshaft position sensor on each cylinder head.
O2 sensor in the exhaust manifold near the engine
No it will not.
Where is the cylinder head temperature sensor on the 2003 ford explorer v8 engine
Need more info, is this the 4 cylinder or 6 cylinder engine and which sensor on bank 1.
Where is cylinder temp sensor on 2000 Ford f250 with v10 engine
Without a signal from the crank sensor, the ECU won't know how fast the engine is turning or "where it is" (which cylinder is about to fire), and the engine will not run. If the sensor is just "somewhat bad" (and gives a weak or irregular signal), the engine might do things like run badly at certain speeds, stop occasionally, or have trouble starting.
The cam sensor is on the driver side of the cylinder head.
