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.
MONITOR STRATEGY
| Required Sensors/Components (Main) | Crankshaft position sensor |
| Required Sensors/Components (Related) | Camshaft 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.
Start the engine [A].
Idle the engine for 20 seconds or more [B].
Turn the GTS on.
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.
·If the judgment result is INCOMPLETE, perform steps [A] through [C] again.
WIRING DIAGRAM
Refer to DTC P033511.
CAUTION / NOTICE / HINT
- NOTICE:
- ·
Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the Freeze Frame Data and Vehicle Control History can be useful for troubleshooting.
(Select Powertrain in Health Check and then check the time stamp data.)
·If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.
- 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:
(a)Connect the GTS to the DLC3.
(b)Turn the ignition switch to ON.
(c)Turn the GTS on.
(d)Enter the following menus: Powertrain / Engine / Data List / Engine Speed.
(e)Start the engine.
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.
·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 C13-1 (VC) - Body ground Ignition switch ON 4.5 to 5.5 V C13-3 (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
