wrench light no code
Worked the 05 powerstroke a little harder than normal this weekend pulling small load 1500lbs.bout 75mph, wrench light came on at top of hill after down shift,no change in performance noticed, ect 213 eot 228 did not get tft before stopping it was 160 when i did, sg2 reads 3 dtc, but no scan code found, wrench cleared of course with key off. Any suggestions why sg2 wont read code? Btw wrench lite never came on again remainder of trip

Some of the conditions that set a wrench light (different than CEL). May have somthing to do with it.

When you see the wrench light, engine is derated (limp mode). One cycle of the ignition off and then back on should clear the light unless the condition still exists. A "soft" code will be set that most inexpensive code readers will not read. Likely causes are high oil temperature, over or under boost (sticking turbo) or FICM voltage low (as per the TSB I posted above). Most OBDII monitors will show oil temp, coolant temp, boost, and FICM voltage. You can monitor those to "figure out" which problem you have or go to a dealership and have it scanned.

Dealer , or a good private shop with the proper software . My Modis helps in these cases . If the wrench light was on , there should be a code that most inexpensive tools are not able to read .But , there should be a record of the code in the PCM .

There is no set temp for the wrench light, depends on operating conditions.
Although on .ORG most have seen 25+ degree differential when the wrench lit up.
