How to diagnose and fix P0024: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
Ford F-350 · 2011–2016
The 6.2L gas V8 in the F-350 develops cam phaser rattle on startup as the phaser locking pins wear. Additionally, the exhaust manifold studs break due to thermal cycling, causing an exhaust leak. Both issues worsen progressively.
Common Symptoms
- Rattle on cold startup lasting 1-5 seconds
- Ticking from exhaust manifold area
- Exhaust smell in cab
- Rough idle when cold
- Power loss at low RPM
- Exhaust leak sound worse when cold
How to Fix
For cam phasers: replace both phasers, timing chains, and solenoids. For exhaust manifold studs: extract broken studs and install upgraded stainless steel studs. Both jobs are labor-intensive due to engine bay size.

Kia Sorento · 2011–2020
P0011 indicates the Bank 1 intake camshaft is over-advanced — the CVVT phaser is stuck or the ECM cannot control it. On the Sorento's Theta II 2.4L GDI (and Lambda V6), the overwhelming cause is a failing intake-side Oil Control Valve (OCV/VVT solenoid) that sticks open or closed, often because it is clogged with sludge from dirty or over-consumed oil, or has failed electrically (spec resistance roughly 6.9-7.9 ohms). Because the OCV depends on clean oil pressure, low oil level and extended oil-change intervals accelerate the failure. The related Bank-1 codes P0014 (exhaust over-advanced) and P0022/P0024 often appear on the same engine family.
Common Symptoms
- check engine light on
- rough idle
- hesitation or slight power loss
- occasional hard start
- minor drop in fuel economy
How to Fix
Test the Bank 1 intake OCV resistance and, as a quick DIY check, swap it with the identical Bank 2 intake OCV to see if the fault follows. Replace the failed OCV — OEM Kia is recommended, as owners report aftermarket solenoids failing quickly — and it is wise to replace intake and exhaust solenoids together. Confirm correct oil level and use the specified oil; clean sludged oil-passage screens. Verify the cam phaser if a new OCV does not clear it.

Ford F-250 · 2011–2022
The 6.2L Boss V8 engine develops a knocking/ticking noise on cold start due to worn cam phasers. The phaser solenoids can also fail. The noise typically goes away once oil pressure builds but worsens over time.
Common Symptoms
- Knocking on cold start
- Ticking noise at idle
- Check engine light
- Rough idle when cold
How to Fix
Replace cam phasers and phaser solenoids. Update to the latest phaser design. Change oil regularly with 5W-20 to maintain proper phaser operation. Consider installing an oil catch can.

Frequently asked questions
What does P0024 mean?
P0024 stands for "Exhaust Camshaft Position Timing - Over-Advanced or System Performance (Bank 2)." This code means the exhaust camshaft on Bank 2 is timed more advanced (earlier) than the computer commanded. The variable valve timing system uses an oil-pressure-driven cam phaser and a control solenoid to set camshaft position; the computer compares the commanded position to the actual measured position. When the exhaust cam on Bank 2 reads too far advanced, P0024 sets. Bank 2 is the side of the engine not containing cylinder number one. Symptoms can include rough idle, reduced power, and poor fuel economy.
What are the most common causes of P0024?
The most common causes of P0024 are: Stuck-open or clogged variable valve timing (oil control) solenoid, Low or dirty engine oil, Failed exhaust camshaft phaser/actuator (Bank 2), Clogged oil control valve screen or oil passages, Stretched or worn timing chain, Wiring or connector fault at the VVT solenoid, Incorrect cam timing from prior service, Faulty PCM/ECM (rare). The specific cause varies by vehicle.
How much does it cost to fix P0024?
Repair costs for P0024 range from $50 to $2,500, depending on the vehicle and root cause.
