Code 45
After much help on this forum over the past year I have got my 1988 F250 351 to the point where it runs quite well. Frustrating as this truck was to fix , it was really satisfying to finally bring it back to good health -sort to speak. As some of you might remember, I had a run in with Rhino Engines about them not giving back my $150 core refund on the reman. I bought from them. The long/short of it was that after several months in correspondence with the Better Business Bureau in New York, Rhino finally refunded the money. I only had to wait 9 months! Pain in the *** company if there ever was one.
I ran a check today and got a code 45 (thermactor upstream during self test) with the engine running. KOEO was fine, an 11.
Would a code 45 point to one of the 2 black solenoids (TAD or TAB) as having gone bad? What is the best way to test this problem out?
Thanks

The code is telling you one of the diverter valves is not in the right position for the test, could be a bad solenoid but could also be a stuck valve or a broken vacuum line between the solenoid and valve.
