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!

Here ya go http://www.jeepsrus.org/index.asp?p=...s_Grand_93to97


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
