DTC P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)

DTC P0340 Camshaft Position Sensor Circuit


DESCRIPTION

The camshaft position sensor (G2 signal) consists of a magnet and MRE (Magneto Resistance Element).
The G2 signal plate has 3 teeth on its outer circumference and is installed on the exhaust 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 G2 signal, and detects the crankshaft angle based on the NE signal.

INSPECTION PROCEDURE

NOTICE:
After replacing the ECM, the new ECM needs registration (LandCruiser RM0000012XK0AVX.html) and initialization (LandCruiser RM000000TIN08IX.html).
HINT:
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.
1.CHECK ENGINE CRANKING CONDITION

  1. Check the engine cranking condition.
