DTC Code | DTC Name |
---|---|
P0016 | Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A) |
P0340 | Camshaft Position Sensor Circuit Malfunction |
P0342 | Camshaft Position Sensor "A" Circuit Low Input (Bank 1 or Single Sensor) |
P0343 | Camshaft Position Sensor "A" Circuit High Input (Bank 1 or Single Sensor) |
DESCRIPTION
The camshaft position sensor (G signal) consists of a magnet and MRE (Magneto Resistance Element).
The G signal plate (camshaft timing gear or sprocket) has 3 teeth on its outer circumference and is installed on the camshaft. When the camshaft rotates, the protrusion on the signal plate and the air gap on the MRE change, causing fluctuations in the magnetic field that generate a voltage in the MRE.
The NE signal plate has 34 teeth and is mounted on the crankshaft angle sensor plate. The NE signal sensor generates 34 signals for every revolution. The ECM detects the camshaft angle based on the G signal, and detects the crankshaft angle based on the NE signal.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory |
---|---|---|---|---|---|
P0016 | Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A) | Phase deviation in crankshaft and camshaft position sensor signals with an engine speed of 650 to 3000 rpm occurs a certain number of times (1 trip detection logic). |
|
Does not come on | DTC Stored |
P0340 | Camshaft Position Sensor Circuit Malfunction |
STA on: No camshaft position sensor signal is sent to the ECM while cranking for 4 seconds or more (2 trip detection logic). STA off: Camshaft position sensor signal is not input with an engine speed of 650 rpm or more (1 trip detection logic). |
|
Comes on | DTC Stored |
P0342 | Camshaft Position Sensor "A" Circuit Low Input (Bank 1 or Single Sensor) | Output voltage of camshaft position sensor is below 0.3 V for 4 seconds (1 trip detection logic). |

CAUTION / NOTICE / HINT
After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click hereНажмите здесь).
After performing the inspection procedure for the camshaft position sensor, if DTC P0016 and/or P0340 is output again, check the following items related to the crankshaft position sensor.
Installation condition of the crankshaft position sensor
No. 1 crankshaft position sensor plate
Connection of the crankshaft position sensor connector
Read freeze frame data using the GTS. 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.
PROCEDURE
CHECK HARNESS AND CONNECTOR (CAMSHAFT POSITION SENSOR - ECM)
Disconnect the camshaft position sensor connector.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
