CAUTION / NOTICE / HINT
NOTICE:
-
Vehicle Control History may be stored in the hybrid vehicle control ECU 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.
- for Nickel Metal Hydride Battery: Click here
- for Lithium-ion Battery: Click here
(Select Powertrain in Health Check and then check the time stamp data.)
Click here
-
If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU, 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:
-
After performing the inspection procedure for the crankshaft position sensor, if DTC P03352A, P033531 and/or P033562 is output again, check the following items related to the camshaft position sensor.
-
Installation condition of the camshaft position sensor.
-
Installation condition of the camshaft.
-
Connection of the camshaft position sensor connector.
-
If no problem is found through this diagnostic troubleshooting procedure, troubleshoot the engine mechanical system.
-
The engine speed can be checked by using the Techstream. To perform the check, perform the following procedure:
-
Connect the Techstream to the DLC3.
-
Turn the power switch on (IG).
-
Turn the Techstream on.
-
Put the engine in Inspection Mode (Maintenance Mode).
Click here
-
Enter the following menus: Powertrain / Engine / Data List / Engine Speed.
-
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 Techstream. 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.
PROCEDURE
1.
|
CHECK SENSOR INSTALLATION (CRANKSHAFT POSITION SENSOR)
|
(a) Visually check the crankshaft position sensor for damage.
(b) Check the crankshaft position sensor installation condition.
OK:
The crankshaft position sensor does not have any damage and is installed properly.
OK
|
|
|
2.
|
CHECK SENSOR INSTALLATION (CAMSHAFT POSITION SENSOR)
|
(a) Visually check the camshaft position sensor for damage.
(b) Check the camshaft position sensor installation condition.
OK:
The camshaft position sensor does not have any damage and is installed properly.
OK
|
|
|
3.
|
INSPECT NO. 1 CRANKSHAFT POSITION SENSOR PLATE (TEETH OF SENSOR PLATE)
|
(a) Inspect the teeth of the No. 1 crankshaft position sensor plate.
OK:
No. 1 crankshaft position sensor plate does not have any cracks or deformation.
OK
|
|
|
4.
|
INSPECT INTAKE CAMSHAFT (TIMING ROTOR)
|
(a) Check the timing rotor of the intake camshaft.
OK:
Camshaft timing rotor does not have any cracks or deformation.
HINT:
Perform "Inspection After Repair" after replacing the intake camshaft.

|
CHECK VALVE TIMING (CHECK FOR LOOSE TIMING CHAIN AND JUMPED TEETH)
|
(a) Remove the cylinder head cover sub-assembly.

(b) Turn the crankshaft pulley and align its groove with the "0" timing mark of the timing chain or belt cover sub-assembly.
(c) Check that the timing marks of the camshaft timing gear assembly and camshaft timing sprocket are at the positions shown in the illustration.
HINT:
If the timing marks are not as shown, turn the crankshaft one revolution clockwise.
OK:
Timing marks on camshaft timing gear assembly and camshaft timing sprocket are at the positions shown in the illustration.
HINT:
If the result is not as specified, check for mechanical malfunctions that may have affected the valve timing, such as a jumped tooth or stretching of the timing chain.
