Question P0402? pinging?

I pulled a p0402 code and check engine light is on, but I also have pinging problem, engine feels hot maybe is normal or maybe not? I don't hear coolant boiling, I just wonder if ol of these can be related to the p0402 code?
"EGR excessive detected" or timing problem?

The P0402 code is often attributable to a failed DPFE sensor.

Regarding the possible connection between pinging and a faulty EGR system:
