Is the Electronic Spark Control a module or a sensor and how do I replace it?

Question:
On 95 Chevy Lumina computer diagnostic reads 43 (ESC) code Advanced Auto parts is confused as to whether this is a module or sensor? And where on this engine is it located?

Answers:

Campro engine knocking sensor location?

There are at least 2 components. There is the crankshaft position sensor and the camshaft position sensor. Crankshaft position sensor is right by the crankshaft (look for the harmonic balancer), should be the only thing there with a wire coming out of it. Camshaft position sensor is located at either end of one of the heads, again just look for a thing with a wire.

Its both...the modual need a sensor to work. the advance guy/gal should have a schematic on the computer showing where the sensor is located, u might want to take it to a car guy/gal and not just replace things willy nilly
