    DTC                 P0340             Camshaft Position Sensor Circuit
                                          Malfunction

CIRCUIT DESCRIPTION
Camshaft position sensor (G22 signal) consist of a signal plate and pickup coil.
The G22 signal plate has one tooth, on its outer circumference and is mounted on the left bank camshafts.
When the camshafts rotate, the protrusion on the signal plate and the air gap on the pickup coil change,
causing fluctuations in the magnetic field and generating an electromotive force in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crankshaft. The NE signal sensor generates 34
signals for every engine revolution. The ECM detects the standard crankshaft angle based on the G22 signal
and the actual crankshaft angle and the engine speed by the NE signals.
   DTC No.                      DTC Detecting Condition                                              Trouble Area

INSPECTION PROCEDURE
HINT:
Read freeze frame data using TOYOTA hand-held tester or OBD II scan tool. Because freeze frame records
the engine conditions when the malfunction is detected, when troubleshooting it is useful for determining
whether the vehicle was running or stopped, the engine warmed up or not, the air-fuel ratio lean or rich, etc.
at the time of the malfunction.

   1       Check resistance of camshaft position sensor (See page IG-1 ).

Reference INSPECTION USING OSCILLOSCOPE
Refer to DTC P0335 on page DI-65 .

                                                          NG          Replace camshaft position sensor.


   OK

   2    Check for open and short in harness and connector between ECM and camshaft
        position sensor (See page IN-31 ).


                                        NG         Repair or replace harness or connector.


  OK



   3    Inspect sensor installation and tooth of left bank camshaft timing pulley.


                                        NG         Tighten the sensor.
                                                   Replace left bank camshaft timing pulley.


  OK



  Check and replace ECM
  (See page IN-31 ).
