DTC P0340 Camshaft Position Sensor "A" Circuit (Bank 1 or Single Sensor)


DESCRIPTION

The camshaft position sensor (G signal) consists of a magnet, iron core and pickup coil.
The G signal plate (timing sprocket) has one tooth on its outer circumference and is installed on the camshaft timing chain gear. When the timing gear rotates, the protrusion on the signal plate and the air gap on the pickup coil change, causing fluctuations in the magnetic field that generate a voltage in the pickup coil.
The NE signal plate has 34 teeth and is mounted on the crank angle sensor plate. The NE signal sensor generates 34 signals for every revolution. The ECM detects the standard crankshaft angle based on the G signal, and detects the actual crankshaft angle and engine speed based on the NE signal.

P0340
DTC Detection Drive Pattern
DTC Detection Condition
Trouble Area
Crank engine for 4 seconds (STA on)
STA on:
No camshaft position sensor signal is sent to the ECM while cranking for 4 seconds or more (2 trip detection logic).
  1. Open or short in camshaft position sensor circuit
  2. Camshaft position sensor
  3. No. 2 camshaft timing sprocket
  4. ECM
Idle engine for 1 second (STA off)
STA off:
When either condition below is met for 1 second (1 trip detection logic):
  1. G signal is not input with an engine speed of 500 rpm or more.
  2. No camshaft position sensor signal is sent to the ECM with an engine speed of 500 to 3000 rpm 20 times or more.
HINT:
If DTC P0340 is stored, the following symptoms may appear:
  1. - Difficult starting
  2. - Misfire
  3. - Combustion noise
  4. - Black smoke
  5. - White smoke
  6. - Lack of power

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click here).
HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
1.INSPECT CAMSHAFT POSITION SENSOR

  1. Disconnect the camshaft position sensor connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    1 - 2
    		Cold
    		835 to 1400 Ω
    1 - 2
    		Hot
    		1060 to 1645 Ω
    HINT:
    In the table above, the terms "Cold" and "Hot" refer to the temperature of the coils in the sensor. "Cold" means approximately -10 to 50°C (14 to 122°F). "Hot" means approximately 50 to 100°C (122 to 212°F).
