Engine light came on and I got strange feedback from store reading codes

The engine light came on in my 09 camry the other day. The auto parts store that scanned it for trouble codes, did not give me a recognizable list, only this:aaEvaporative emission system reference or orifice high aaflowprobable causeaa1. Open or short circuitaa2. Poor elect. Connectionaa3. Evap system leakaa4. Pump module faulti've checked and cleaned the gas cap and found the locations of the o2 sensor, egr valve, charcoal cannister (not even going to touch that one) but I was wondering if there was anything else I should test/clean before I take it in for probably some very expensive repairs. Thanks
