DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Note |
P034000 | Camshaft Position Sensor "A" Bank 1 or Single Sensor No Signal (sub) | No camshaft position sensor (for intake camshaft) signal to the sub ECM while engine running | ECM | Comes on | SAE: P0340 |
MONITOR DESCRIPTION
While the engine is running, when the VV1 (VV2) signal is not input to the sub CPU even though the VV1 (VV2) signal is input to the main CPU, the ECM judges that a malfunction has occurred in an internal ECM circuit, 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
-
Connect the GTS to the DLC3.
-
Turn the ignition switch to ON.
-
Turn the GTS on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the ignition switch off and wait for at least 30 seconds.
-
Turn the ignition switch to ON.
-
Turn the GTS on.
-
Start the engine.
-
Idle the engine for 10 seconds or more.
-
Enter the following menus: Powertrain / Engine / Trouble Codes.
-
Read the pending DTCs.
HINT:
-
If a pending DTC is output, the system is malfunctioning.
-
If a pending DTC is not output, perform the following procedure.
-
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
-
Input the DTC: P034000.
-
Check the DTC judgment result.
GTS Display | Description |
NORMAL | -
DTC judgment completed
-
System normal
|
ABNORMAL | -
DTC judgment completed
-
System abnormal
|
INCOMPLETE | -
DTC judgment not completed
-
Perform driving pattern after confirming DTC enabling conditions
|
HINT:
-
If the judgment result is NORMAL, the system is normal.
-
If the judgment result is ABNORMAL, the system has a malfunction.
CAUTION / NOTICE / HINT
HINT:
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
1. | CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P034000) |
(a) Read the DTCs.
Powertrain > Engine > Trouble Codes
Result | Proceed to |
P034000 is output | A |
P034000 and other DTCs are output | B |
HINT:
If any DTCs other than P034000 are output, troubleshoot those DTCs first.
