P0340: Engine speed sub sensor (Camshaft position sensor) - disconnection
INFORMATION
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
•

<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
