SFI SYSTEM(w/ Canister Pump Module), Diagnostic DTC:P033511, P033515, P03351F, P03352A, P033531

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 NE signal to detect the crankshaft position and engine speed.

• 

  *a	2 V/DIV.
  *b	20 ms./DIV.

  Reference: Inspection using an oscilloscope.

  Tech Tips

  The correct waveform is as shown.

  ECM Terminal Name	Between NE+ and NE-
  Tester Range	2 V/DIV., 20 ms./DIV.
  Condition	Idling with warm engine

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).

• The crankshaft position sensor output voltage is above or below the threshold.

MONITOR STRATEGY

CONFIRMATION DRIVING PATTERN

1. Connect the GTS to the DLC3.

2. Turn the engine switch on (IG) and turn the GTS on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4. Turn the engine switch off and wait for at least 30 seconds.

5. Turn the engine switch on (IG) and turn the GTS on.

6. Start the engine.

7. Idle the engine for 20 seconds or more [A].

8. Enter the following menus: Powertrain / Engine / Trouble Codes [B].

9. Read the pending DTCs.

   Tech Tips

   
   

   • If a pending DTC is output, the system is malfunctioning.

   • If a pending DTC is not output, perform the following procedure.

10. Enter the following menus: Powertrain / Engine / Utility / All Readiness.

11. Input the DTC: P033511, P033515, P03351F, P03352A or P033531.

12. 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
    N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

    Tech Tips

    
    

    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform steps [A] and [B] again.

PROCEDURE

1. READ VALUE USING GTS (ENGINE SPEED)

   
   

   1. Connect the GTS to the DLC3.

   2. Turn the engine switch on (IG).

   3. Turn the GTS on.

   4. Enter the following menus: Powertrain / Engine / Data List / Engine Speed.

      
      Powertrain > Engine > Data List

      Tester Display
      Engine Speed

   5. Start the engine.

   6. Read the values displayed on the GTS while the engine is running.

      Standard
      Correct values are displayed.

      Tech Tips

      
      

      • To check the engine speed change, display the graph on the GTS.

      • If the engine does not start, check the engine speed while cranking.

      • If the engine speed indicated on the GTS remains at zero (0), there may be an open or short in the crankshaft position sensor circuit.
