[GELÖST] P0335 - Stand heute auf Parkplatz und der PU sprang nicht an...

Zitat von Barney

Und... Kann das auch damit zusammenhängen das mir der Truck vor ein paar Wochen 2 mal während der Fahrt ausgegangen ist?

Zumindest ist das möglich. Ohne CKP-Signal kein Zündfunke! - Man muß dabei beachten, daß beim Nachmessen (zB. mit Oszi) oft ein Signal vorhanden ist und man denkt, es wäre alles gut. Wichtig bei den Steuergeräten ist aber, daß das Signal eine Mindestspannung sein muß.

Einen Spannungsabfall kann man zB. schon durch schlechte Steckerverbindungen haben, so daß das Signal dann gelegentlich mal nicht ausreicht. Es kann aber auch ein leichter Kabelbruch sein, der gelegentlich zum tragen kommt.
Da nach Deiner "Rumwackelei" erstmal wieder alles funktionierte, könnten die beiden o.g. Ursachen in Frage kommen.

Der Kurbelwellensensor, auch OT Geber genannt, leidet manchmaldaran, daß am Simmerring etwas Öl tropft.
Dann sammelt sich dort Dreck und stört das ganze.

CKP System Variation Learn Procedure

Important
For additional diagnostic information, refer to DTC P1336 .

Install a scan tool.
With a scan tool, monitor the powertrain control module for DTCs. If other DTCs are set, except DTC P1336, refer to Diagnostic Trouble Code (DTC) List for the applicable DTC that set.
With a scan tool, select the crankshaft position variation learn procedure.
Observe the fuel cut-off for the engine that you are performing the learn procedure on.
The scan tool instructs you to perform the following items:
Block the drive wheels.
Apply the vehicles parking brake.
Cycle the ignition from OFF to ON.
Apply and hold the brake pedal.
Start and idle the engine.
Turn OFF the A/C.
Place the vehicles transmission in Park (A/T) or Neutral (M/T).
The scan tool monitors certain component signals to determine if all the conditions are met to continue with the procedure. The scan tool only displays the condition that inhibits the procedure. The scan tool monitors the following components:
Crankshaft position (CKP) sensors activity--If there is a CKP sensor condition, refer to the applicable DTC that set.
Camshaft position (CMP) sensor activity--If there is a CMP sensor condition, refer to the applicable DTC that set.
Engine coolant temperature (ECT)--If the engine coolant temperature is not warm enough, idle the engine until the engine coolant temperature reaches the correct temperature.
With the scan tool, enable the crankshaft position system variation learn procedure.

Important
While the learn procedure is in progress, release the throttle immediately when the engine starts to decelerate. The engine control is returned to the operator and the engine responds to throttle position after the learn procedure is complete.

Slowly increase the engine speed to the RPM that you observed.
Immediately release the throttle when fuel cut-off is reached.
The scan tool displays Learn Status: Learned this ignition. If the scan tool does NOT display this message and no additional DTCs set, refer to Symptoms - Engine Mechanical in Engine Mechanical. If a DTC set, refer to Diagnostic Trouble Code (DTC) List for the applicable DTC that set.
Turn OFF the ignition for 30 seconds after the learn procedure is completed successfully.

DTC P0335
Circuit Description
The crankshaft position (CKP) sensor signal indicates the crankshaft speed and position. The CKP sensor is connected directly to the powertrain control module (PCM), and consists of the following circuits:

The 12-volt reference circuit
The low reference circuit
The CKP sensor signal circuit
Conditions for Running the DTC
DTCs P0101, P0102, P0103, P0341, P0342, or P0343 are not set.
The camshaft position (CMP) sensor is transitioning.
The mass air flow (MAF) is more than 3 g/s in the crank mode.
The MAF is more than 5 g/s in the running mode.
Conditions for Setting the DTC
The PCM determines no signal from the CKP sensor for more than 3 seconds.

Action Taken When the DTC Sets
The control module illuminates the malfunction indicator lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
Conditions for Clearing the MIL/DTC
The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.
Diagnostic Aids
The following conditions may cause this DTC to set:

Poor connection or poor terminal tension at the sensor--Refer to Testing for Intermittent and Poor Connections in Wiring Systems.
Crankshaft reluctor wheel damage or improper installation
Excessive air gap between the CKP sensor and the reluctor wheel
The engine running out of fuel
Foreign material passing between the sensor and the reluctor wheel
Excess crankshaft end play causes the CKP sensor reluctor wheel to move out of alignment with the CKP sensor. This could result in any one of the following:

A no start
A start and stall
Erratic performance
For an intermittent, refer to Intermittent Conditions .

Test Description
The numbers below refer to the step numbers on the diagnostic table.

This step determines if the fault is present.

This step simulates a CKP sensor signal to the PCM. If the PCM receives the signal, the fuel pump will operate for about two seconds.

The CKP system variation learn procedure must be performed anytime the relationship between the CKP sensor and the CKP reluctor wheel is changed.

The CKP system variation learn procedure must be performed anytime the relationship between the CKP sensor and the CKP reluctor wheel is changed.

Nee nee, da ist nix mit Öl und Staub und Dreck und Störung bei dem Motörchen .....
Der CKP sitzt beim 8,1l BBC im Motorblock im Ölbad und schleift direkt auf der Kurbelwelle. Der wird auch nicht defekt sein, denn der kennt eigentlich nur heil oder kaputt.

Du findest den .... ähm, vermutlich garnicht .... jedenfalls nicht mit normalen Fingerchen. Der sitzt hinten zwischen dem linken Zylinderkopf und der Getriebeglocke im Motorblock. Das Kabel dazu kommt aus dem rückwärtigen dicken Motorkabelbaum.
Ausbauen kann man ihn nur, wenn man zuvor die Benzinleitungshalterung an der Getriebeglocke abschraubt und die EVAP-Leitung trennt. Das Ding ist leider sehr lang und empfindlich; deshalb brauchjt man zum Ausbau Platz.

Uiii, der Harry der Teufelskerl .... war wieder schneller ... na egal.

Viel wichtiger ist ja wohl, auch von der Arbeit wech kommen!!!! Nich hin!!!
