P0341: Engine speed sub sensor (Camshaft position sensor) - rationality
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 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
• The number of the engine speed sub sensor pulses per 2 engine revolutions is continuously abnormal (other
than 5 pulses). (For example, 100 seconds for 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.
