HYBRID / BATTERY CONTROL MOTOR GENERATOR CONTROL SYSTEM P034006 Camshaft Position Sensor "A" Circuit Bank 1 or Single Sensor Algorithm Based Failure P034062 Camshaft Position Sensor "A" Circuit Bank 1 or Single Sensor Signal Compare Failure
DESCRIPTION
The motor generator control ECU (MG ECU) (built into the inverter with converter assembly) compares the engine speed value calculated based on the camshaft position signal input from the ECM versus the engine speed value received from the ECM via CAN communication, and when it has frequently judged that the engine speed is high and the deviation between the engine speed values is large, it will store DTC P034006 or P034062.

MONITOR DESCRIPTION
Calculated engine speed is calculated from the time interval of crankshaft position signals. Fail counter is counted up when difference between engine speed and calculated engine speed is over the criteria. Malfunction is detected when fail counter value is over the criteria.

CONFIRMATION DRIVING PATTERN
- HINT:
- ·
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
·When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for 2 minutes or more.
Turn the ignition switch to ON (IG) and wait for 5 seconds or more.
Turn the ignition switch to ON (READY) and wait for 5 seconds or more.
Depress the accelerator pedal to start the engine.
Keep the engine running for 20 seconds.
Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
Check the DTC judgment result.
- HINT:
- ·
If the judgment result shows NORMAL, the system is normal.
·If the judgment result shows ABNORMAL, the system has a malfunction.
·If the judgment result shows INCOMPLETE, perform driving pattern again.
