When the microphone detected engine knock (ping) the control electronics would adjust the ignition (injection) or turbo pressure (turbo). Modern Saab engines, like the one in the 9-5, do not have a traditional knock sensor. Instead they detect engine knocking (ping) by measuring the ionization inside the cylinders just after ignition. They do this in the direct ignition cartridge by using the fire plugs as sensors. I don't know if the error message indicates that there is something wrong with the direct ignition cartridge, but it is easy to replace the cartridge for a test. -- G–ran Larsson Senior Systems Analyst hoh AT approve DOT se
