SES Light

[89REATTAJIM]

   My '89 overheated, found the lower hose had disconnected from the radiator. Thought the t'stat had stuck shut, so replaced t'stat with a new 180. This event caused the SES light to come on. Now showing history codes E014, E041, and B552. Also current codes E041, B122 And B123. 

   Should I now just clear the codes and see if any reappear?, if so, how do I clear them?

One of the CRT selectons in diagnostics (off-warm) is "Clear codes" one for ECM and another for BCM. Get the diagnstics booklet from Ronnies.

   Tks Padgett. Will give this a try. Haven't touched base for a while; hope all is well with you.

Was able to clear codes. Overheating problem seems to be fixed. SES light is still on and not running up to par. Showing current code E041. Does this indicate a bad magnet or other possible problem??

Magnet, sensor, connectors, wiring...
