DTC: P0336
EN01H02127030602016070
P0336: Engine speed main sensor (Crankshaft position sensor) - rationality
INFORMATION
1.
Technical description
•
The engine speed main sensor (crankshaft position sensor) consistently measures pulses from the engine speed
main sensor (crankshaft position sensor).
<Description of malfunction>
•
Pulses from the engine speed main sensor (crankshaft position sensor) cannot be correctly sensed.
2.
DTC set condition
(1)
DTC detection condition
•
Battery voltage is in the range of 10 V to 16 V.
•
Engine speed of 500 r/min or more
(2)
Judgement criteria
•
Make a judgment when the abnormal number of engine speed main sensor pulses (not 56 pulses) per engine
revolution is continuously detected. For example, 50 seconds at 750 r/min
3.
Reset condition
•
After normal operation is restored.
4.
Indication, warning or system control regulation when the DTC is set.
•
MIL: ON
•
SVS light: OFF
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
•
Improper pulses
•
Sensor is disconnected from measuring site or sensing unit is malfunctioning (due to adhesion of dirt, damage,
etc.)
•
Irregular contact (disconnection or poor fit of connector)
•
Harness disconnection or short-circuit
