Good evening and welcome to JustAnswer!!!
Do you have a scantool? The No Bus is telling you that the Bus communication is down at the moment which means the different modules PCM, MIC, ABS, Etc can't communicate with each other because either a module has failed or you have a wiring issue.. If you had a scantool you could do a module scan and see which ones are responding and which ones aren't.. WIthout a scantool you will need to start disconnecting modules until the No Bus quits flashing and then replace that module..
The P1391 is a intermittent loss of crankshaft or camshaft sensor signal. Were the sensors OEM or aftermarket sensors that you replaced?
replaced the sensor from auto zone. duralast I believe. I do have a scan tool and I will try that now
I just tested the 5v wire at the tps sensor and its 3v. I have 12 at the battery. when I disconnect the crank or cam sensor the voltage does not change at the tps
3v is not good.. Start by disconnecting the cam-crank-map-tps and see if you get 5v back. If not then test for 5v coming out of PCM.. If still 3v then replace the PCM.
