Cost of diagnosing the P0011 2004 TOYOTA PRIUS code
The cost of diagnosing the P0011 2004 TOYOTA PRIUS code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the P0011 2004 TOYOTA PRIUS code detected?
After the ECM sends the target dutyandcycle signal to the OCV, the ECM monitors the OCV current to establish an actual dutyandcycle. The ECM determines the existence of a malfunction and sets the DTC when the actual dutyandcycle ratio varies from the target dutyandcycle ratio.
P0011 2004 TOYOTA PRIUS Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

P0011 2004 TOYOTA PRIUS Meaning
The Engine Control Module (ECM
) controls the Oil Control Valve (OCV) to regulate the intake camshaft angle. As a result of the angle change, the engine timing is advance or retard. Optimizing engine timing will help the engine improve torque and fuel economy, and the exhaust emissions decrease under overall driving conditions. The Variable Valve Timing (VVT) system includes the Oil Control Valve (OCV) and VVT controller. The ECM
detects the actual intake valve timing using signals from the camshaft and crankshaft position sensors, and performs feedback control.
