Please go to Autozone, Kragen, Checker, or whichever you have around where you live. They can scan for free, I am much more familiar with the new codes, should start with P and 4 digit numbers.

21 "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)

It is a 4-cylinder, single head. I am not certain why it says "Bank 2"

55 HO2S Heater Resistance (Bank 1, Sensor 3)
