I have a Coleman saluspa that is reading E02 . We have tried everything to clear what else could it be

You need to check the thermostats in the heater circuit as well. The element is held in place my 2 nust from the bottom where the wires attach.

SOURCE: OBDC code says bad camshaft pos sensor, circuit

has 2 sensors if dohc

SOURCE: code p0403

The code is EGR cicuit open. I would believe that to mean that if the cicuit is open that the EGR needs to be replaced.
The worst thing, I think, a tech can do is to start throwing parts at a problem, but sometimes that is the only answer if you want to get something repaired without spending hours tracking things down.
Please let me know how it goes.

Here are the locations of the fuses and relays. F-31 through f-42 probably are the one you want to look at. These are probably all tied together from looking at your codes. Your mass air flow sensor is also giving you an alarm. If your not finding any blown fuses or bad relays it might very well be the PCM (Power train control module) itself that is going bad. A dealer will have to check that out for you.

SOURCE: I have a Comfort Zone CZ1500W showing an AO5 error code. I have 9 ohms across each element. The fan thermostat reads open. When I bypass it the fan runs, but no heat. The element thermostat reads

Everytime I turn on the CZ heater, the display reads A05 and then it goes away when i set the temp. As far as I can see and feel, I'm not experiencing any issues with the heating, fan, or thermostat or the extension cord running hot. I'm concerned that something could be wrong or unsafe, with Comfort Zone filing for Chapter 7, anyone know who is offering support or a number I can contact?
