Hi All,
First off excuse me if this question has been already been covered.
We have a 93 245 with the check engine light on. It has been on at least 2 years.
The code its showing is 1-2-3. If I disconnect the battery the light returns on after 90 seconds or so.
Being in California we need the check engine light out to pass smog. Our car has always passed smog.
It runs perfectly. A few things of note. We have a tropical fan clutch which causes the engine to run cool. I've replaced the coolant temp sensor and the connector to it.
Any help is greatly appreciated!
