DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Note |
---|---|---|---|---|---|
P034031 | Camshaft Position Sensor "A" Bank 1 or Single Sensor No Signal | No camshaft position sensor (for intake camshaft) signal for 5 seconds at an engine speed of 600 rpm or higher (1 trip detection logic). * |
| Comes on | SAE: P0340 |
*: When the engine is being stopped or started automatically by stop and start system control, the ECM does not monitor the camshaft position sensor signal.

MONITOR DESCRIPTION
If no pulse signal is transmitted by the camshaft position sensor (for intake camshaft) despite the camshaft rotating, the ECM interprets this as a malfunction of the sensor.

PROCEDURE
1. | CHECK HARNESS AND CONNECTOR |
HINT:
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
(a) Disconnect the camshaft position sensor (for intake camshaft) connector.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
(d) Turn the ignition switch off and wait for at least 30 seconds.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
D90-3(VC) - D90-1(VVI+) | Ignition switch off | 1.425 to 1.575 kΩ |
D90-2(VVI-) - Body ground | Always | Below 1 Ω |
NG |
![]() | GO TO STEP 4 |
|
2. | CHECK SENSOR INSTALLATION AND CONDUCT VISUAL INSPECTION (CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT)) |
*a | Clearance |
(a) Visually check the camshaft position sensor (for intake camshaft) for damage.
(b) Check the camshaft position sensor (for intake camshaft) installation condition.
OK:
The camshaft position sensor (for intake camshaft) does not have any damage and is installed properly.
NG |
![]() | SECURELY REINSTALL CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT) |
|
3. | INSPECT INTAKE CAMSHAFT (TIMING ROTOR) |
(a) Check the timing rotor of the intake camshaft.
OK:
Camshaft timing rotor does not have any cracks or deformation.
HINT:
Perform "Inspection After Repair" after replacing the intake camshaft.

![]() | REPLACE INTAKE CAMSHAFT |
4. | CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR (FOR INTAKE CAMSHAFT) - ECM) |
(a) Disconnect the camshaft position sensor (for intake camshaft) connector.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
D90-1(VVI+) - D104-90(VV1+) | Always | Below 1 Ω |
D90-2(VVI-) - D104-89(VV1-) | Always | Below 1 Ω |
D90-3(VC) - D104-88(VCV1) | Always | Below 1 Ω |
D90-1(VVI+) or D104-90(VV1+) - Body ground and other terminals | Always | 10 kΩ or higher |
D90-2(VVI-) or D104-89(VV1-) - Body ground and other terminals | Always | 10 kΩ or higher |
D90-3(VC) or D104-88(VCV1) - Body ground and other terminals | Always | 10 kΩ or higher |
OK |
![]() | REPLACE ECM |
