P0016 P0016 crankshaft position - camshaft position correlation (bank 1 sensor a)
Description
In the vvt (variable valve timing) system, the appropriate intake valve open and close timing is controlled by the ecm. The ecm performs intake valve control by performing the following: 1) controlling the camshaft and camshaft timing oil control valve, and operating the camshaft timing gear; and 2) changing the relative positions of the gaps between the camshaft and crankshaft
Monitor description
The ecm optimizes the valve timing by using the vvt (variable valve timing) system to control the intake camshaft. The vvt system includes the ecm, the oil control valve (ocv) and the vvt controller.
The ecm sends a target duty-cycle control signal to the ocv. This control signal regulates the oil pressure supplied to the vvt controller. The vvt controller can advance or retard the intake camshaft.
The ecm calibrates the intake valve timing by setting the intake camshaft to the most retarded angle while the engine is idling. The ecm closes the ocv to retard the cam. The ecm stores this value as the vvt learning value. When the difference between the target and actual intake valve timings is 5°ca (crankshaft angle) or less, the ecm stores it.
If the vvt learning value matches the following conditions, the ecm determines the existence of a malfunction in the vvt system, and sets the dtc.
This dtc indicates that the angle between the intake camshaft and the crankshaft is incorrect due to factors such as the timing chain having jumped a tooth.
This monitor begins to run after the engine has idled for 5 minutes.

Inspection procedure
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, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
Notice:
After replacing the ecm or adjusting intake valve timing, confirm that the dtc output does not recur.
Ok: no dtc output
