Description
(1) cylinder reference sensor
"a" 3-way grey connector
Make: VALEO
Type: Hall effect sensor
Role
The cylinder reference sensor informs the engine ECU of the position of the camshaft in order to know which cylinder is in the compression phase
Function
(1) cylinder reference sensor
"b" target
"c" permanent magnet
"d" detection cell
"e" output signal
"t" time
During which a target is passing in front of the permanent magnet of the cylinder reference sensor: the output signal is in low status
During which there is no target in front of the permanent magnet of the cylinder reference sensor: the output signal is in high status
