Arrow Bypass Knock sensor 89 chevy 350

In my '89 Chevy K1500 the 350 engine has a lifter tick that comes and goes about every ten minutes(starts soft gets louder and louder then stops). The knock sensor picks this up and does it's job, retards timing. So I have attempted to hang a knock sensor out in the breeze to avoid the timing being retarded for no reason. Now the truck is setting a knock sensor code. I soldered a wire to a brass fitting then attached that to ground. Then threaded the knock sensor into the fitting. Then zip tied the mess to a section of wiring harness. I saw somewhere that it expects to hear knock at full throttle and if it does not it will set a code. Is this true on my truck? Any suggestions on how to bypass it without setting a code?? Does the ECM do anything when the code is set? Or does it just set it and ignore the Knock Sensor?
