Note:
The malfunction "P0327 / 16711" is set if the output voltage of the knock sensor is too low (below 0.2 V) (coolant temperature
over 20 C (68 F)/ engine speed greater than 3500 RPM and engine load greater than 16%). The ignition angle is then
retarded by 12 crankshaft in the knocking areas of the map (engine load greater than 40%).
