Well I allowed my brother to use my truck to deliver a vehicle he sold up in the Carolina's. Well I got my truck back today and its not the same at all. Its a 2005 3500 DRW with Auto tranny and all should be stock.

I cycled the switch and the follwing codes are showing:


P - 1753

P- 1751

P-201


Any ideas where to start? It did not shift aggressive at all, but it did not slip. Any ideas will be apprciated.

It has 14o k miles on it, I hope just getting broken in good.


Let me know where I should Start. I have not ways to reset the code or anything else.

P0201-INJECTOR #1 CONTROL CIRCUIT - DIESEL
P1751-TRANSMISSION THROTTLE VALVE POSITION MINIMUM RANGE
P1753-TRANSMISSION THROTTLE VALVE MECHANICAL PERFORMANCE


Sounds like several different problems. May be a wiring issue on the P0201 code. Will have to do some diagnosis to be sure. Just mow much are you ready to get in to? I can get you the diagnostics flow charts if you want?

 

Im pretty mechanically inclined, Just not on a diesel.. Ive always said Ill try anything once ....... So fire away with any suggestions or ideas you may have.... Is there a way to reset and see if it throws the codes again? Could it be in a leap mode of some type?

P1751-TRANSMISSION THROTTLE VALVE POSITION MINIMUM RANGE PERFORMANCE




For a complete wiring diagramRefer to Section 8W

Theory of Operation
The transmission throttle valve cable has been replace by the transmission throttle valve actuator (TTVA). The TTVA consists of an electric DC motor, two potentiometers, and a gear drive system. The TTVA is mechanically connected to the transmission throttle valve in the valve body by the “D” shaped opening in the bottom of the TTVA shaft.

The Transmission Throttle Valve Actuator (TTVA) does not require any mechanical adjustments. All changes in throttle valve position are controlled by the Engine Control Module (ECM).

The TTVA does require an initialization period after the actuator has been removed or replaced. After the actuator has been removed or replaced, move the ignition to the ON position for thirty (30) seconds. This will allow the ECM sufficient time to perform the internal calibration procedures to learn the TTVA's current “zero” position.

When Monitored:
Ignition on and with or without engine running with transmission in the park or neutral position. Note: Not monitored when either the engine is cranking or while vehicle is moving.

Set Condition:
Each time the ignition is cycled to the on position, the ECM commands a TTVA internal calibration procedure (autozero) to determine the zero position. If the TTVA does not reach a calibrated minimum position in a predetermined amount of time, the DTC will set.

Possible Causes
TRANSMISSION THROTTLE VALVE ACTUATOR BINDING
TRANSMISSION THROTTLE VALVE COMPONENTS
TRANSMISSION THROTTLE VALVE ACTUATOR


Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)

Diagnostic Test
1. CHECK IF THE DTC IS CURRENT

--------------------------------------------------------------------------------
Ignition on, engine not running.
With the scan tool, read Engine DTCs.
Record the Freeze Frame data for the reported DTC.
With the scan tool, erase DTCs.
Turn the ignition off to the lock position.
Using the Freeze Frame data recorded earlier, try to duplicate the conditions in which the DTC originally set.

NOTE: It may be necessary to road test the vehicle to duplicate the original set conditions.


With the scan tool, read Engine DTCs.

Did the DTC reset?

Yes
Go To 2

No
Go To 5



2. CHECK TTVA FOR SIGNS OF DAMAGE

--------------------------------------------------------------------------------
Turn the ignition off to the lock position.

Same wiring diagram as P1751.

 

wow lots of info there, will be fun locating everthing Im suppose to trouble shoot lol

Anyone ever been hit with this combination of codes before? If so what was the cuplrit?

Thanks for the help

 

Also Now Im showing Codes 1751 1753 and code 217..... I could have possibly misread the 217 for 201, But does the 217 go along with the other problems any better than the 201?

Do I need to drop the pan to get to the items I need to check?

I hope im not looking at a tranny rebuild, Its got me worried now.

Steve

 

ok a newbie question here.... I am getting a 217 code which is overheat condition to the best I can tell.... Once the sensor tells the CPU its to **** hot to go into self preservation mode, Once it comes up with a normal temp will the code reset, or do i need to go drop a hundred for the reader?

I am guessin if it could be a bad sensor which is causing it to think its overheated... Just a guess and Im sorta trying to pull something outta my you know what. Help me out here guys with some thoughts.

Steve

 

Sounds like the TTVA is not working and resulting in the engine running hot. Has your temp been high? Might make sure everything is o.k. in the cooling system , but I think the root cause for everything is in the trans. Without a scanner it is going to be hard to actuate the TTVA or even see what the computer is trying to make it do. First thing I would do is a visual of the cooling system - levels, guage , ect. Then do a visual on the trans fluid, level, color, and then look at the wiring at the trans. Under the truck on the driver's side. Look for damaged misrouted wires ect. Start there and let us know what you find.

 

Ok ill do that, Oreilly auto parts has a Code Scanner for like 124 that is suppose to work on these trucks, will that allow me to actuate it and test it?


The levels are fine, all looks good on coolings system, I only have some concerns about the fan clutch.

The wires are all connected and in proper place..... Nothing obvious there all with tight connectors... I see a actuator of sometype that is directly above where the shift selector enters the tranny. Made by Siemmens.


Steve

 

Probably not. Those usually just spit ou the codes, which you already know you can do on your own! Kind of a rip off!

Here what your looking for. Also the removal/install procedures.

REMOVAL




Remove the bolts (2) (Transmission Throttle Valve Actuator Installed) holding the transmission throttle valve actuator (TTVA) (1) to the transmission case.
Allow the TTVA (1) to rotate clockwise away from the transmission.




Remove the wiring connector (2) (Transmission Throttle Valve Actuator Removal) from the TTVA (1).
Lift the TTVA (1) straight upward and off the throttle valve shaft (3).

 

yep that what I was looking at.... So do we trouble shoot it with it off and check for movement? Also I bet if thats what it is its gonna be an OEM item which means expensive as hell.

 

Looks like 134.00 list price. Part number is 53041140AB.

 

thats not too bad, Should I remove and turn on switch and see if it moves? Is there anything internal that could keep it from moving>?

So we are saying the module is bad and needs to be replaced correct?
