That is reported to the ECM so that adjustments can be made to bring the system back to preset parameters and stop the problem
besides being a knock sensor , it may be also a problem heated oxygen sensor (HO2S) in the exhaust manifold before the cat converter which reports to the ECM the combustion gas composition for adjustment to the air/fuel ratio

??There are two types of DTC's, 1 trip DTC's and 2
??A 1 trip DTC is for a condition that requires
immediate attention such as a catalyst damaging
??A 2 Trip DTC is one that a condition must be found
during 2 consecutive trips such as an EGR fault.
??Most Monitors do not set a DTC and light the MIL
when a vehicle fails a test for the first time during a
DRIVE CYCLE. If a test is failed on a second
consecutive DRIVE CYCLE the MIL will light and a
DTC is stored in the vehicles powertrain control
