STOP AND START  STOP AND START SYSTEM  P033562  Crankshaft Position Sensor "A" Signal Compare Failure  


DESCRIPTION

The crankshaft position sensor sends an engine speed signal (NE signal) to the ECM. The engine speed signal is then sent directly from the NEO terminal of the ECM to the engine stop and start ECU. Additionally, the ECM sends the engine speed to the engine stop and start ECU via CAN communication. The engine stop and start ECU compares the NE signal and engine speed received via CAN communication to check for errors in the NE signal.

If the NE signal is abnormal, the engine stop and start ECU will blink the stop and start cancel indicator and stores DTC P033562.

CONFIRMATION DRIVING PATTERN

CONFIRMATION AFTER TROUBLESHOOTING


HINT:
·

If the cable is disconnected from the battery terminal, stop and start control is prohibited until refresh charge is completed.

In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item "Status of Battery Charge Control" changes from "Refresh Charge Mode". (Usually, idling the engine for 5 to 60 minutes with the battery fluid temperature at 11°C (51°F) or higher, the refresh charge will be completed.)

·

If the GTS is not available and the Data List item "Status of Battery Charge Control" cannot be checked, charge the battery by idling the engine for approximately 5 to 60 minutes or driving the vehicle, and then drive the vehicle and check that stop and start control operates.

If the engine is started with the hood open, the system determines that a jump start has occurred. Therefore, make sure that the hood is closed before starting the engine and driving the vehicle.

·

After the refresh charge completes, turn the ignition switch off, wait for at least 30 seconds, and then start the engine again. If the vehicle enters refresh charge mode again while the engine is idling, the initial refresh charge did not properly complete, so wait for the refresh charge to complete.

·

Allow the engine to idle for 3 minutes after it is warmed up and check that the engine idle speed is within 50 rpm of the target idle speed.
