followed the video to a letter. at idle the tps was see'in 1.316 volts. at wot it was see'in 3.687 volts. was getting 5.144 with the sensor unpluged. idk what to do next

 

Often times the brake light switch can be the culprit too. Does your cruise control work?

Other things to check/try:

Is your alternator putting out 14+?

Are the batteries good?

A ground strap from the alternator to the core support never hurts on these trucks.

These trucks are notorious for having grounding issues, which can cause this kind of behavior. If the alternator or the batteries are getting weak, it only takes a couple tenths of voltage one way or the other to screw these things up.

 

DTT Noise Filter usually fixes the lock unlock lock unlock issue.

No the cruise doesnt work. Alternator and batterys are good. Have the bd diesel noise insolater installed.

 

bump to the top. could use some advise to get this fixed

 

still lookin for some help with this problem

 

The pressure transducer and govener solenoid are fairly common causes. Have you tried a ground strap? That's the first thing my Trans guy always does on these trucks.
