I have a '95 626 5spd with 168k miles on it. I cannot find a definitive answer as to what causes the following DTCs:

17

23

25

41

I hope to find that one stupid problem is causing all of this. It's all intermittent. I can clear my codes and not see them for a while. The light will come on at random times under random conditions.. The dash light and codes just show up randomly EG I can clear the codes, drive a week or 3, have no codes or light, and then the light comes on and it's always these 4 when I check. Doesn't make any sense to me.

Any thoughts?

 

give this a read , it is the same on the 626/MX6/probe. http://homepage.ntlworld.com/mx6-uk/malf/malfcode.htm full explanation of codes are near the bottom of the page.
