Key Diagnosis Code Question

So I read this FAQ
"Just the trick ..
to save you some money and avoid the dealership if you can fix it yourself.



How to get the codes:
Cycle the ignition key On - Off - On - Off - On within 5 seconds.
Count the number of times the check engine lamp on the dash flashes on and off. The number of flashes represents the trouble code. There is a slight pause between the flashes representing the first and second digits of the code. Longer pauses separate individual two digit trouble codes.
Example: Lamp flashes 5 times, pauses, and flashes 5 more times. This indicates a code number 55. A code 55 will always be the last code to be displayed. This will indicate the end of all stored codes.
This method should work for Jeeps up to 1997 - I have yet to find a way of reading the codes on '98 TJ's or Cherokees/Grand Cherokees."

And got 33, 2, 55

How should I interpret that? Do all the sequences start with a 3, which would mean my code is a 32?

"An open or shorted condition detected in the EGR solenoid circuit. Possible air/fuel ratio imbalance not detected during diagnosis."

no, you've got codes 33, and 2, the only code of that nature is the 55, the 'end of transmission' code.

Correction - have redone my error codes. Ends up I am getting 12, 32, 55(end)

Code 12-Memory to controller has been cleared within 50-l00 engine starts.
Can someone interpret this for me?

Code 32-Exhaust Gas Recirculation (EGR) solenoid circuit-open or short detected in the EGR solenoid circuit/EGR system failure-required change in fuel/air ratio not detected during diagnostic test.
Is this due to no cat? Or should I be looking elsewhere?

12 - Your battery has been disconnected within the last 50 starts.

32 - Your no cat, might have caused this, but I don't know.

First check to see that all the lines are connected to the erg valve. Then disconnect and re-connect the electrical connector; for starters. If the erg is not working then the air to fuel ratio will be rich, gas mileage will suck, and the engine could ping!

About the code 32... is this the code that is sometimes thrown if the gas-cap is not sealed all the way?

EGR = Exhaust Gas Recirculation
