Hey guys, recently picked up a smarty so in the process of tuning and changing tire size, I checked my DTCs and got a couple I hadn't seen before so looking for a sanity check on these.


First one is


I'm curious if this is a typical code to expect since I'm using a lock up switch? Seems like it, but some assurance would be nice.


Second is


Does this relate to the lockup switch as well? Or something else? My alternator seems to be doing it's job. Appears to come up with at least 12-ish volts prior to start and gets the needle up over 14 when driving so appears to be charging. What else should I be looking for?


FWIW, I've cleared both codes and they come back every time.

Whoops, realized I pasted the same code link. Second one should be updated in my first now, it's P0622. 


I didn't follow any troubleshooting yet because I wanted to see if this was normal for having a lock up switch installed. The 0622 code is a weird one and I don't have a scan tool that can do freeze frame (unless obdii can??) so I read through and eventually it gets to replacing the PCM based on resistance being too high/low, so got me wondering if that's just another byproduct of having the switch spliced into it?

P1765 is from using a jumper harness for a lock up switch. Not familiar with the P0622.

Oh well, charging system doesn't seem to be having a problem, all voltage looks good. Only thing I can think of is the alternator possibly on the way out (I'll have to check ac noise soon) or my batteries are finally on their last leg and throwing a weird code. Either way I'll let it go until something more obvious comes up to point me in a better direction.
