P0024 Code - Exhaust Valve Timing Control Performance Bank 2
Quick Answer
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the exhaust valve. Common causes include Faulty exhaust valve timing control solenoid valve, Exhaust valve timing control solenoid valve harness is open or shorted, Exhaust valve timing control solenoid valve circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0024 Description
The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the exhaust valve timing control solenoid valve depending on the driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.
The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position.
What are the Possible Causes of the DTC P0024?
- Faulty exhaust valve timing control solenoid valve
- Exhaust valve timing control solenoid valve harness is open or shorted
- Exhaust valve timing control solenoid valve circuit poor electrical connection
- Faulty Crankshaft Position Sensor (POS)
- Faulty Camshaft Position Sensor
How to Fix the DTC P0024?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0024 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
