P0024 TOYOTA Possible Causes
- Dirty Oil
- Variable Valve Timing (VVT) circuit is open or shorted
- Oil Control Valve (OCV) circuit is open or shorted
- Faulty variable valve timing (VVT)
- Faulty oil control valve (OCV)
- Damaged Engine Control Module (ECM)
How do I fix code P0024 TOYOTA?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- If the engine oil is clean and the VVT and OCV circuits are OK, replaced the VVT to resolve the problem.
Cost of diagnosing the P0024 TOYOTA code
The cost of diagnosing the P0024 TOYOTA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
After the ECM sends the target duty cycle signal to the OCV, the ECM monitors the OCV current to establish an actual duty cycle. The ECM determines the existence of a malfunction and sets the DTC when the actual duty cycle ratio varies from the target duty cycle ratio.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of power
- Engine rough idle
P0024 TOYOTA Description
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.
