98 Accord EX
Hello everyone, and thank you in advance for any and all help.
I am buying a used 98 Accord for my son. The car seems to be in great condition, but there are a few diagnostic codes I'm trying to work with to make sure it's a good car for him. I got all of these codes by jumpering pins 5 and 16 on my OBD-II plug, and then counting the flashes. I also went to Autozone and had them read the code, for verification.
CEL code: 70
D4 code: 16
OBD-II code: P1768
So these actually seem to both be codes for the same issue. My problem is actually in nomenclature. The CEL code 70 and the OBD-II code both point to a "A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE " A"", but the D4 code seems to point toward a "linear solenoid".
Also, when I read through the FSM, it refers to a linear solenoid, but not the other one. Also, on this parts list: Honda Automotive Parts , it refers to a linear solenoid as well, but also makes no mention of the other one.
So are these the same thing? Am I overthinking this?
Also, occasionally I see mention of a "lock-up" solenoid, and on the Autozone printout one of the definitions of the code P1768 is "Lock up clutch does not engage-stuck in 4th gear. Probable cause..."
I've seen the lock up solenoid as a separate part number, so there's more confusion.
Could someone please straighten out my thinking?
Thanks again!

Re: 98 Accord EX
Also, for clarification. The first time I drove this car it ran great, shifted great, no issues, no transmission codes. Then I stopped the car and jumpered the OBD-II to find out what the CEL code was and the ABS code was. The first time I jumpered it it did pins 8 to 12. That obviously didn't work, corrected myself, and jumpered 5 to 16. Got my codes. Then when I started the car back up to drive it again I had the D4 flashing light and a new CEL code (the first CEL code was from a poorly tightened gas cap).
So did I screw something up by jumpering the OBD-II wrong? I went through and checked all of the fuses and none were blown. The car had been sitting for a while before he decided to sell it, so could it just be coincidence? That the solenoid just happened to go out right then as I was checking the codes? Or does Occams Razor apply, and the simplest explanation of me screwing something up applies?
