I got a bmw 335i and it’s an 07 i have 3 codes P1417 p0123 and p0222 the car cranks but at the end it just cranks the full time and don’t turn on at all anything helps those are the only codes I tried clearing the codes and nothing I did remove the engine because it needed a new one but everything was done correctly that’s the only trouble I have anything helps

Try a throttle adapation reset. See if that will allow the vehicle to start. Your faults are throttle/accelerator pedal signal faults.

Here is the method i use:

1. Get in the vehicle and close door.
2. Insert key and press the start-stop button without stepping on the brake pedal. (Basically accessory mode)
3. Press the accelerator pedal all the way down (past kick down detent) and hold for approx. 30sec-1 min. I do a 1min.
4. After a minute, without lifting off the accel pedal, press the start stop again to shut off accessories.
5. Lift off the pedal and wait about 2-3 mins.
6. Try starting the vehicle .


All your doing in allowing the learned adaptations to be reset. Hopefully this will start the vehicle.

If it doesn’t then more in depth diag will need to be performed. Such as pedal low and high voltage tests, signals to the throttle body etc…

Hopefully it does start!

Let us know how this goes. 🙂

Unfortunately that did not work iam open for more ideas anything helps something don’t seem to be working

Check your fuses for fuel pump. Do you hear your fuel pump working?

2 things you may have and im gust guessing without proper testing.

1) Leaky injectors
2) High or Low Pressure fuel pump.

Can you check your plugs to see if they look wet? If so most likely yiu have leaky injecitors?

Those 3 codes all relate to the Throttle Valve. BMW Fault Code Lookup Definitions & LINKS to Fault Info "Service Notes":
P1417 | 2D09 | DME: THROTTLE | MSD80
https://bmwfault.codes/XMLDiagView?d...AAMgA4ADAANAA=

P0123 | 2CF9 | DME: Throttle-valve potentiometer 1 | MSD80
https://bmwfault.codes/XMLDiagView?d...cAMAAxADAANAA=

P0222 | 2CFA | DME: Throttle-valve potentiometer 2 | MSD80
https://bmwfault.codes/XMLDiagView?d...cAMAAzADAANAA=

Please provide:
1) Last-7 Characters of Vehicle VIN, as MANY electrical changes occurred 3/1/2007 in MIDDLE of 2007 Model Run.
2) Also, please indicate Make/Model of Scan Tool or Diagnostic Software (INPA/ISTA) available.
3) Indicate IF you have cheap (~$10 HFT/Amazon) Multimeter for Testing.

ISTA Wiring Diagram for 2/2007 (2007A) 335i E92 is attached to NEXT Post. CHECK the Connector X6390 at the Throttle Valve. If NOT an obvious wiring/connector Fault, test wiring between Throttle Valve & DME. If Throttle Valve is from Replacement Engine, Swap with that on Old N54 (if applicable), and/or TEST the Voltage Signals from Valve.

If you need Test Suggestions, please provide information requested above.

Attached are ISTA ScreenPrints referenced in PRIOR Post, re 2/2007 N54 335i.

My last 7 vin numbers are P032534 and my scan tool that I use is a Carly I’m not sure the year and I do have a meter to test wiring and voltage

[autotrans 335i e92]

And by the way gbalthrop how the I test the throttle valve to dme and it looks like it was rewired the connector to the throttle valve but I can’t get a for sure until I can test if it’s getting current

Throttle Valve wiring for your 11/2006 build N54 (Chassis -- don't have info on replacement engine), is SAME as provided in prior post for 2/2007 N54.

Your Throttle Valve on N54, & my N52K Throttle Valve are Different, as I have VVT (Valvetronic) as the Throttle. Principle of operation MAY be similar:
1) 5V supply via Blue wire at X6390/2;
2) Ground via Black/Violet wire at X6390/6;
3) Signal from Throttle Potentiometer 1 via Yellow/Blue wire at X6390/1;
4) Signal from Throttle Potentiometer 2 via Yellow wire at X6390/4;
5) Signal 1 from DME to Throttle Drive Motor via White/Green wire at X6390/3;
6) Signal 2 from DME to Throttle Drive Motor via White/Yellow wire at X6390/5; I would assume that the DME reverses polarity in those two signals to operate the Throttle Valve Drive Motor in proper direction to Open/Close Throttle, based upon voltage signals from TWO Acclerator Pedal Hall Sensors.

My interpretation of your 3 codes is that you have issues in the Signals FROM the Throttle Valve, and/or in the voltage supply & ground wires, as identified in (1) through (4) above. Since I don't have an N54, I cannot verify that myself.

On my N52K, the SUM of the voltages (Spannung) from the two Throttle Valve (Drosselklappe) Potentiometers is 5.0 Volts, with one voltage increasing & the other decreasing with change of Throttle Butterfly angle.

I will attach an INPA ScreenPrint showing "Drosselklappe Spannung" for my N52K to Next Post. Those Voltage/ Spannung values are on Bottom Row of ScreenPrint.

I'm NOT a Carly Fan, basically 'cuz I have YET to see anyone who appears to understand WHAT it can do, and/or HOW to get it to do that. Hope YOU are the exception to that, OR at least have Manual/Documentation you can refer to, so YOU can see Live Data of Throttle Valve Potentiometer Signals (as received by the DME) with Ignition ON, Engine OFF, changing Accelerator Pedal Position.

If you CAN'T determine HOW to get Carly to show that Live Data, you can always test for Voltage at each of the wires mentioned in (1), (3) & (4) above, & for continuity to ground at (2), using a Multimeter. If my suggestions are NOT clear, please post back.

Got your PM. I prefer to use the open forum to communicate, 'cuz EVERYONE can participate/ learn, PLUS I can attach ScreenPrints as you see here. We have ALL levels of skill & experience on the Forum, so NO REASON to feel bashful about asking questions. As stated BEFORE, I don't have an N54, so can't be CERTAIN my suggestions about your Throttle Valve wiring are correct, but I've looked at enough ISTA wiring diagrams, & Bentley Manual, to believe they ARE Correct.

My Suggestions:
1) Take up to 15 minutes trying to find HOW to use Carly to view 'Live Data' of INPUTS from two Throttle Valve Potentiometer signals to the DME. "Live Data" is a display of the Signals received by the DME (Engine Control Module). You can use that to determine if there is ANY signal from the 2 Potentiometers.

2) If you find a screen you believe is showing that Voltage data, please attach a photo of the Carly Screen, showing us what YOU see.

3) Using a Multimeter, Test as follows, Ignition ON, Engine OFF (NOT running):
a) Since your connector MAY have been "Modified" (if taped), inspect EACH of the FOUR (4) wires at the connector, X6390. Ignore the two motor wires at sockets #3 & #5 for NOW. The wire colors SHOULD be, at the respective Connector Socket:
(1) Yellow/Blue, Potentiometer 1 Signal to DME; Test/Report Voltage; (OR if wire color differs);
(2) Blue, 5-Volt Voltage Supply to Sensor Unit; Test/Report Voltage;
(4) Yellow, Potentiometer 2 Signal to DME; Test/Report Voltage;
(6) Black/Violet, Continuity to Ground; Test/Report Ohms/Continuity;

Just test that much and report your results, with any questions about how to test. Generally, to test Voltage, set meter to DC (Direct Current) Volts, and range to 20 Volts or less (you expect voltage readings in 0V to 5V range). Put Red meter probe in socket, contacting Metal insert, & Black meter probe in contact with good Chassis Ground/Metal.

To test for Continuity to Ground, set meter to mid-range Ohms/Resistance setting, such as 2,000 ohms (Ω). Meter display should read "1", or Infinite Resistance. Touch Red Meter Probe to Black probe. Meter should read "0"/Zero, or nearly so, indicating continuity or closed circuit.

See the ISTA ScreenPrints previously provided for wiring, wire colors, Connector Locations, & Connector View, with Socket number identification.
