Question

The _____________ sensor, senses rotation of engine camshaft for speed and timing of injection.

(a) throttle position

(b) manifold pressure

(c) camshaft position

(d) knock

I got this question during an internship interview.

I would like to ask this question from Electronic Injection System topic in portion Electronic Injection Systems of IC Engine

Answer 1

Correct answer is (c) camshaft position

Easiest explanation: The camshaft position sensor, senses rotation of engine camshaft for speed and timing of injection whereas the throttle position sensor, senses the movement of the throttle plate so that the mixture flow can be adjusted for engine speed and acceleration while the manifold pressure sensor, monitors vacuum in the engine intake manifold so that the mixture strength can be adjusted with changes in engine load.
