MONITOR DESCRIPTION
DTC P0016 and P0018
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 applied 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 intake camshaft has been installed toward the crankshaft at an incorrect angle, caused by factors such as the timing chain having jumped a tooth.
This monitor begins to run after the engine has idled for 5 minutes.
DTC P0017 and P0019
The ECM checks valve timing (VVT learning value) on the exhaust side while the
engine is running at a
low speed, in order to monitor the gap between current and target valve timings
on the exhaust side. The
VVT learning value is calculated from the positions of the camshaft and
crankshaft. The camshaft will
come to the most retarded position when the engine is running at a low speed. If
the camshaft position is
normal, the VVT learning value should be within the specified range. If the VVT
learning value is not within
the specified range, the ECM determines this as a malfunction.

INSPECTION PROCEDURE
HINT: Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction
1 CHECK VALVE TIMING (CHECK FOR LOOSE AND A JUMPED TOOTH OF TIMING CHAIN)
OK: The matchmarks of the camshaft pulley and the camshaft bearing cap align when the notch of the crankshaft pulley is in the "0" position.
NOTICE: After replacing the ECM or adjusting intake valve timing, confirm that the DTC output does not recur.
