A lot of times just a short,bad connection,etc won't throw a code on the speedo! Frustrating I know,but this what happens with efi systems,hard to be a "shade tree" mechanic any more! I'm just able to comment on what happened the most on the efi systems,and the map sensor harness kit was the most common problem we had.There is also the crank sensor wiring, tps wiring that could be the cause. As far as the sensors themselves,they usually were not the problem,JUST the wiring. If you read the "sticky" posts in this section about the sensor wiring,it may help! OPT
