Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P034400

Condition




The camshaft is divided into a number of segments (flanks). There is a toothed (the teeth are located between each segment) pulsed wheel on the camshaft, which the Engine control module (ECM) reads via the camshaft sensor.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The camshaft's segments are too few under a certain crankshaft rpm.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Start of engine.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.

Substitute value
- Engine speed sensor signal.

Possible source
- Open-circuit on the signal cable.
- The signal cable is short-circuited to ground.
- The signal cable is short-circuited to voltage.
- Damaged mass air flow sensor.

Fault symptom[s]
- Nothing.






Diagnostic trouble code (DTC) information ECM-P034400

Condition




The camshaft is divided into a number of segments (flanks). The camshaft houses a gearwheel with a number of teeth (the teeth are positioned between each segment) that are read by the engine control module (ECM) via the camshaft position sensor. The diagnostic trouble code is generated if the control module detects too few segments for a certain number of crankshaft revolutions.
The diagnostic trouble code (DTC) can be diagnosed when the engine is running.

Substitute value
- Engine speed sensor signal.

Possible source
- Open-circuit on the signal cable.
- The signal cable is short-circuited to ground.
- The signal cable is short-circuited to voltage.
- Damaged mass air flow sensor.

Fault symptom[s]
- Nothing.
