327 EVP or DPFE CIRCUIT BELOW MINIMUM VOLTAGE

328 EGR CLOSED VOLTAGE HIGHER THAN EXPECTED

452 INSUFFICIENT INPUT FROM VEHICLE SPEED SENSOR (VSS)

542 FUEL PUMP SECONDARY CIRCUIT FAILURE- PCM TO GROUND
....This code came up because I removed the midship tank from my truck and only taped the plug up until I find away to connect the wires on it to complete the circuit.

628 CONVERTER CLUTCH ERROR (E4OD)


I have a gut feeling that my (VSS Sensor) could be causing the other problems but need some guidence on it. I know very little on how the sensors react with one another.

Some reason the codes repeated them selves before the test completed. Should this of happened?

 

Maybe this will help; The reason I pulled the codes to begin with was the truck wanted to mis off and on while driving and lightly pushing the gas, then again never does it when firm with the gas.

 

Alittle code help Please.

 

Years past, the procedure was to always correct the first code given. Go in sequence, receive code, repair and retest. That way the first malfunction noted by the computor when repaired is verified and eliminates any other this code is a result of that code. If I make sense.

 

I would think now that the codes are displayed in number sequence inorder to make it less random to look up.

I crawled under today to check out the speed sensor on the rear of the transmission and the only thing I saw there was the speed cable and afew wires attached to the harness it connects and my trans lines on the other half. No Sensor and back to square one.

I hope to have more time to look everything over the weekend.

 

In disagreement with your logic. Hopefully, the correct people will chime in for both of our behalves.

 

Replace DPFE Valve (from Dealer)
Replace EGR Valve Regulator (Dealer)
ur right VSS code is tripping the other one.

 

Codes are displayed in numerical order. The VSS error is causing the torque converter error. There are EGR issues going on, you need to start testing sensors, solenoids, and check for vacuum. I get the fuel pump secondary circuit failure code on occasion too with no real reason for it, I haven't figured out what to do about it. It's not from the tank being removed as long as you don't select that tank. I'm thinking that it's caused by my fuel pump because it's on its way out, but I'm not sure.

 

Oh yeah, that is the VSS with the wires to it at the speedometer cable. There's also another one in the rear differential but that's supposed to be just for the ABS on your year.

 

I wasnt in question of your theory on how the codes were displayed "Good Old Bill" I was referring to the order that I thought the codes would be displayed.

I appreciate all the help, as I said before; This code and sensor stuff is a whole new ball game for this old boy.
Hell with Waldo, Im still searching for that darn VSS.

If i was to pull the egr valve to clean it, will carb cleaner really work well at cleaning the egr? Actually will the gasket be reuseable?
