92 Wrangler computer codes 12 33 and 55
My CEL light is showing on my Jeep, turned out to be a bad thermostat as the code indicated the motor wasn't heating up fast enough and running too cool. I installed a new TStat and disconnected the battery to reset and my CEL is still lit. Now I get codes 12 33 and 55.
12- battery has been disconnected
33- no AC relay
55- end of codes
To me this indicates all the codes are clear as my Jeep didn't have AC and the only way to reset the Codes is disconnecting the battery. It's also my understadning that all non-ac jeeps will show a code 33 when retrieved, but shouldn't cause a CEL light.
So why would I still have a lit CEL light with those 2 codes- 12 and 33?
