| P034031 | Camshaft Position Sensor "A" Bank 1 or Single Sensor No Signal | Diagnosis condition:
·
The engine is running (600 rpm or more) Abnormal condition: ·
No camshaft position sensor signal. Malfunction time: ·
5 seconds or more Trip logic: ·
1 trip detection logic Detection conditions: ·
Continuous Sensors/components used for detection (Main): ·
Camshaft position sensor Sensors/components used for detection (Related): ·
Crankshaft position sensor |
·

Reference: Inspection using an oscilloscope.
MONITOR DESCRIPTION
When the engine is running and no camshaft position sensor signal is received for 5 seconds or more, the ECM determines that the camshaft position sensor circuit is malfunctioning and illuminates the MIL and stores a DTC.
MONITOR STRATEGY
| Required Sensors/Components (Main) | Camshaft position sensor |
| Required Sensors/Components (Related) | Crankshaft position sensor |
| Frequency of Operation | Continuous |
CONFIRMATION DRIVING PATTERN
Refer to DTC P03402A.
WIRING DIAGRAM
Refer to DTC P034011.
CAUTION / NOTICE / HINT
- NOTICE:
- ·
Vehicle Control History may be stored in the hybrid vehicle control ECU if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.
(Select Powertrain in Health Check and then check the time stamp data.)
·If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.
- HINT:
- ·
If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
·Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the DTCs.
- Powertrain > Engine > Trouble Codes
- 50001 372
- Result:
Result Proceed to DTC P034031 is output A DTC P034031 and P034011 or P034015 are output B
- HINT:
-
If DTC P034011 or P034015 is output, perform troubleshooting for it first.

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
Disconnect the camshaft position sensor connector.
Turn the power switch on (IG).
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Condition Specified Condition C10-3 (VC) - Body ground Power switch on (IG) 4.5 to 5.5 V C10-1 (VVI+) - Body ground Power switch on (IG) 3.0 to 5.0 V
Turn the power switch off.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition C10-2 (VVI-) - Body ground Power switch off Below 1 Ω
