MONITOR DESCRIPTION
A DTC will be stored if any of the following occurs:
-
The crankshaft position sensor signal (NE signal) is not received by the ECM when the engine is being cranked.
-
The crankshaft position sensor signal (NE signal) is not received by the ECM when the engine is running.
-
The engine stalls and the engine speed signal value decreases rapidly (under normal conditions the engine speed will decrease gradually).

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.
Click here
-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
-
Connect the Techstream to the DLC3.
-
Turn the engine switch on (IG).
-
Turn the Techstream on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the engine switch off and wait for at least 30 seconds.
-
Start the engine.
-
Idle the engine for 20 seconds or more [A].
-
Run the engine at an engine speed of 1000 rpm for 5 seconds or more [B].
-
Turn the Techstream 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.
-
Input the DTC: P03351F, P03352A or P033531.
-
Check the DTC judgment result.

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 Techstream. To perform the check, follow the procedures below:
-
Connect the Techstream to the DLC3.
-
Turn the engine switch on (IG).
-
Turn the Techstream on.
-
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
(a) Check the engine cranking condition.

READ VALUE USING TECHSTREAM (ENGINE SPEED)
|
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List / Engine Speed.
Powertrain > Engine > Data List
Tester Display
|
Engine Speed
|
(e) Start the engine.
(f) Read the values displayed on the Techstream while the engine is running.
Standard:
Correct values are displayed.
HINT:
-
To check the engine speed change, display the graph on the Techstream.
-
If the engine does not start, check the engine speed while cranking.
-
If the engine speed indicated on the Techstream remains at zero (0), there may be an open or short in the crankshaft position sensor circuit.
