MONITOR DESCRIPTION
When the engine is running and no camshaft position sensor signal is received for 5 seconds or more, the ECM determines that the camshaft position sensor circuit is malfunctioning and illuminates the MIL and stores a DTC.

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.
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:
- If no problem is found through this diagnostic troubleshooting procedure, there may be a mechanical problem with the engine.
- 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 DTC OUTPUT (DTC P034031 AND P034011 OR P034015) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs.
Powertrain > Engine > Trouble Codes
