What causes a turbocharger speed sensor to go inactive?
What causes a turbocharger speed sensor to go inactive?
This fault becomes inactive any time the speed signal from the turbocharger speed sensor returns. If the fault occurs intermittently, look for causes of intermittent open or short circuits in the turbocharger speed sensor circuit (including the speed sensor pigtail connector).
When do I get the fault code 2398?
The fault code is set when the actual position of the drive changes the geometry of the turbocharger does not match the specified for more than 10 seconds. Error code 2398 Engine:
Where is the target on the turbocharger shaft?
The target on the turbocharger shaft is a ground flat in the center of the shaft. As the flat on the turbocharger shaft spins past the speed sensor, a signal is generated.
When does the ECM detect the turbocharger speed?
The ECM detects that the turbocharger speed is detected to be less than 600 rpm for more than 1 second when the engine speed is greater than 1200 rpm. • The ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails. • The ECM will estimate turbocharger speed.
What is the diagnostic code for a turbo problem?
P0045 is a diagnostic trouble code for “Turbo/Super Charger Boost Control Solenoid Circuit/Open.” In the simplest of terms, this particular code indicates that the Engine Control Unit has detected an abnormal reading in the supercharger boost control circuit or turbocharger.
This fault becomes inactive any time the speed signal from the turbocharger speed sensor returns. If the fault occurs intermittently, look for causes of intermittent open or short circuits in the turbocharger speed sensor circuit (including the speed sensor pigtail connector).
The fault code is set when the actual position of the drive changes the geometry of the turbocharger does not match the specified for more than 10 seconds. Error code 2398 Engine:
Why does turbo speed drop to 0 on Insite?
Turbo speed in INSITE drops randomly to 0 while engine is running and then comes back. Also, engine is derates currently because of the error codes, but if I unplug the turbo speed sensor all codes become inactive and problem doesn’t reoccur.
