DESCRIPTION
The crankshaft position sensor system consists of a crankshaft position sensor plate and Magneto Resistance Element (MRE) type sensor. The crankshaft position sensor plate has 34 teeth at 10° intervals (2 teeth are missing for detecting top dead center), and is installed on the crankshaft. The crankshaft position sensor generates 34 signals per crankshaft revolution. The ECM uses the crankshaft position sensor signal (NE signal) to detect the crankshaft position and engine speed.
DTC No.

MONITOR DESCRIPTION
If the output voltage transmitted by the crankshaft position sensor remains low or high, the ECM interprets this as a malfunction in the sensor circuit, illuminates the MIL and stores a DTC.

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 ignition switch to ON.
-
Turn the Techstream 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.
-
Turn the ignition switch to ON [A].
-
Turn the Techstream on.
-
Wait 5 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.
-
Input the DTC: P033511 or P033515.
-
Check the DTC judgment result.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
HINT:
-
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 ignition switch to ON.
-
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
1.
|
READ VALUE USING TECHSTREAM (ENGINE SPEED)
|
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List / Engine Speed.
Powertrain > Engine > Data List

|
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.
