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.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Warning Indicate	Memory	Note
P033562	Crankshaft Position Sensor "A" Signal Compare Failure	All of the following conditions are met for 10 seconds (1 trip detection logic): · Normal communication between the ECM and the engine stop and start ECU. · Engine speed (NE signal) is below 6000 rpm. · Difference between the NE signal that is sent directly from ECM and the engine speed that is sent via CAN is 300 rpm or higher.	· Wire harness or connector · Crankshaft position sensor · ECM · Engine stop and start ECU	Blinks	DTC stored	SAE Code: P0335

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.

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Turn the GTS on.

Clear the DTCs.

Powertrain > Stop and Start > Clear DTCs: 50002 392

Start the engine and wait for at least 15 seconds.

Check that DTCs are not output.
