P0340: Engine Speed Sub Sensor - Disconnection; Dtc: P0340 - Hino Motors HINO 155 series Workshop Manual

DTC: P0340

P0340: Engine speed sub sensor (Camshaft position sensor) - disconnection
INFORMATION
Engine speed sub sensor
1. Technical description
• The engine speed sub sensor (camshaft position sensor) consistently measures pulses from the engine speed sub
sensor (camshaft position sensor).
<Description of malfunction>
• Pulses from the engine speed sub sensor (camshaft position sensor) cannot be sensed.
2. DTC set condition
(1) DTC detection condition
• Battery voltage is in the range of 10 V to 16 V.
• Engine speed of 0 r/min or more
(2) Judgement criteria
• With the engine running, the engine speed sub sensor (camshaft position sensor) does not detect pulses for
continuous 0.8 seconds or longer. (at 750 r/min)
3. Reset condition
• After restoration to normal condition.
4. Indication, warning or system control regulation when the DTC is set.
• MIL: ON
• SVS light: OFF
• Idling stop system is not available.
5. Symptoms on the vehicle when the DTC is set
<Symptoms on the vehicle due to backup control (fail safe function)>
• –
<Symptoms on the vehicle due to malfunction>
• –
6. Pre-inspection work
• Check that the battery voltage is in the normal range.
7. After-inspection work
• Clear all past DTCs.
• Check that no DTC is stored after test drive.
8. Estimated failure factors
• Abnormal resistance of sensor
• Loose/disconnected sensor or failure in sensing area (contamination, clogging or breakage)
• Irregular contact (disconnection or poor fit of connector)
• Harness disconnection or short-circuit
