*: When the engine is being stopped or started automatically by stop and start system control, the ECM does not monitor the crankshaft position sensor signal.
Reference: Inspection using an oscilloscope.
MONITOR DESCRIPTION
When the engine is cranking and no crankshaft position sensor signal is received for 4.7 seconds or more, the ECM determines that the crankshaft position sensor circuit is malfunctioning and illuminates the MIL and stores a DTC.

| Frequency of Operation | Continuous |
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.
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.
Start the engine [A].
Turn the GTS on.
Idle the engine for 20 seconds or more [B].
Enter the following menus: Powertrain / Engine / Trouble Codes [C].
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.
Proceed to the next screen and enter the DTC to be checked.
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.
·[A] to [C]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
·When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
- HINT:
- ·
If no problem is found by this diagnostic troubleshooting procedure, check for problems by referring to the engine mechanical section.
·The engine speed can be checked by using the GTS. To perform the check, follow the procedures below:
1. Connect the GTS to the DLC3.
5. Start the engine.
3. Turn the GTS on.
4. Enter the following menus: Powertrain / Engine / Data List / Engine Speed.
The engine speed may be indicated as zero despite the engine running normally. This is caused by a lack of NE signals from the crankshaft position sensor. Alternatively, the engine speed may be indicated as lower than the actual engine speed if the crankshaft position sensor output voltage is insufficient.
·DTC P03352A may be stored due to poor engine cranking. Before performing troubleshooting for this DTC, perform the check engine cranking operation procedure.
·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.

-
Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.
Disconnect the crankshaft position sensor connector.
Turn the ignition switch to ON.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection Condition Specified Condition C13-3 (VC) - Body ground Ignition switch ON 4.5 to 5.5 V C13-1 (NE+) - Body ground Ignition switch ON 3.0 to 5.0 V
Turn the ignition switch off.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition C13-2 (NE-) - Body ground Ignition switch off Below 1 Ω
- Result:
Proceed to OK NG
