Ne - G Phase Shift (Dtc P0016 / 636-7); Crankshaft Position Sensor Side; Camshaft Position Sensor Side - Kubota V3800-CR-TE4 Diagnosis Manual

V3800-CR-TE4,V3800-CR-TIE4, DM

(1) NE - G Phase Shift (DTC P0016 / 636-7)

Behaviour during malfunction: (Invalid G signal)
• Engine hesitates at start-up
Detection item:
• Large phase shift between NE (crankshaft position sensor) pulse and G (camshaft position sensor) pulse
DTC set preconditions:
• Engine is operating above low idle speed
• Battery voltage is normal
• Sensor supply voltage VCC# is normal
• NE signal is normal
• G signal is normal
• Coolant temperature is 10 °C (50 °F) or higher
DTC set parameter: (Approximate)
• Phase difference between NE pulse and G pulse within ± 0.26 rad (± 15 °)
Engine warning light:
• ON
System action:
• None
Recovery from error:
• Diagnostic counter = zero
1. Check the Crankshaft Position Sensor and Camshaft
Position Sensor Signals
1. Run the engine and check the values of the "Engine speed
active flag" and "Cam speed active flag" with the data monitor
function.
Factory
Constantly ON.
specification
OK Check the DTC (speed signal phase shift) again.
OK Normal.
NG Check each pulsar for damage and deviation, and correct.
NG Refer to "Crankshaft Position Sensor (NE sensor) Abnormality" (page
1-S178) and "Camshaft Position Sensor (G sensor) Abnormality" (page
1-S183).
NOTE

(Crankshaft position sensor side)

• The NE pulsar has deviated.
• A large magnetic substance has adhered to the pulsar,
hardened and rotates together with it, or the teeth have
been ground down.

(Camshaft position sensor side)

• The G pulsar plate is disconnected.
• The cam gear unit is disconnected, etc. (large side
clearance).
• A large magnetic substance has adhered to the pulsar,
hardened and rotates together with it, or the teeth have
been ground down.
