I was getting error codes P0117, P0118 & P0113. The P0117 & P0118 have to do with the engine temperature sensor and the P0113 is related to the TMAP sensor. I changed my engine temperature sensor and went for a test ride and it was still acting up. I checked my error codes. No more P0117 and P0118 error code but I still had the P0113 code (TMAP sensor). I checked under the wiring looms and found one of the 3-way soldered connections where one of the wires branched off to the TMAP sensor had vibrated and broken off at the wire going to the TMAP sensor. I added a short length of wire and soldered everything back and shrink tubing all the bare connections. I already had a new TMAP sensor so I swapped out the old one for this new Fueling TMAP sensor. The old TMAP sensor was likely OK but being in there for 8 years I figured may as well change it. Went out for another test ride and now my 120R Trask Turbo FLHX is back to running smooth and strong like it always did. And no more error codes.
