Is there a connector so that the check engine light can be diagnosed?
I have a 1993 Subaru Legacy. Just replaced the manual transmission. Don't remember if the "Check Engine" light had been coming on or not. Don't think so. It's on now though. The Auto Zone rep said that the 1993 models did not have a jack to connect too. Does anyone else know different? If it does where is located?

is this car an automatic transmission?
if it is then you will need to check the gear selector switch on the transmission. I have seen one that would not properly engage for the park/neutral and reverse switches to function but the car was still drivable.
Read Memory Mode : used to pull codes which have been stored in memory. It is most effective in detecting poor contact of wiring harness connectors. To enter this mode, connect the read memory connector with the ignition ON . D Mode : used to diagnose and test the entire injection system. To enter this mode connect the test mode connector with the ignition ON . On the Legacy and SVX, the ignition must be ON with the engine running. F-Check Mode : used to measure the performance characteristics of the injection system components. When working in this mode, a Select Monitor or equivalent scan tool is required. U Check Mode : operates during normal engine operation. It signals the driver using the MIL only when components necessary for start-up and drive are faulty. The read memory and test connectors must be disconnected with the ignition ON for this mode to be operational.
There are two sensors, one for ECU temp. readings with two pin connector and other one with only one wire, which has been probably disconnected when you replaced the CPC solenoid - very close position.
ok , unplugged ox sensor cause engine light is on , then check the air filter and fuel filter for dirty and replace,connect the ox sensor, then disconnect the negative battery terminal few minutes, reconnect and test
I had the same problem, and the reason was the sensors, will need to change the catalytic sensors
some vehicle have two, they called front and back, get under the car and locate them, they have a
electrical plug and are easy to remove, is like removing a spark plug but some require a special socket
I hope this help
