Re: knock ping sensor
Obviously not
Knock sensor doesn't make any noise ;
is just a device to tells the computer that the engine is knocking so it can adjust the timing
What you have is " engine knock"; the engine is pre-igniting under load due to bad timing / bad fuel
could be many things
There is no error code for IAC faults

Re: knock ping sensor
You have detonation problems in the cylinders ( worst when engine hot)
Timing is out , cr*p gas ,engine temp too hot ; could be one or all those or other problems
Start with the basics by setting timing

low temp thermostat without changing the fans on/off temperature in the chip wont do much

Re: knock ping sensor
this is not going to fix your pinging issue. you need to lower your timing
