No the pinging isn'tfrom using premium gas or booster, it can be from to much carbon on piston raising the compression to a bad ect to a lot of things. Attached you'll find apic of ectlocationfor a 2.3L as you didnt' give engine size. The gauge could be bad though you have two ect's one for the gauge and one fo the pcm. On the ect gauge one groudn the woire and see if gauage goes up if it does then teh sender is bad if not it'sthe gague maybe
