Hi Stephen:
Are these P-codes? P1321; P1323?
If so, these are knock sensor codes. Two of the knock sensors are no longer reporting so the ECUs detected failurs and sent the CELs. Not very likely these are failed knock sensors simultaneously; more likely a wiring issue via the sensors.

OK Good Stephen. Interested in hearing back.
These knock sensors play a vital role in OBDII Engine management systems by contributing to the control of engine timing. Therefore, the sensors are monitored and have to "report in" they are active and alive even if there is no engine knock. In your case, two sensors are no longer reporting they are active. Again, not likely they both failed, so more likely something has interrupted their signal.
All the Best,
Steve
