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.
Common Symptoms
- Cam phaser rattle on startup
- Ticking from exhaust manifold area
- Exhaust leak sound worse when cold
How to Fix
For cam phasers: replace both phasers, timing chains, and solenoids. 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 code P0014 (Bank 1 exhaust over-advanced) and, on the V6, the Bank 2 codes 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 on the V6, 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
Owners of the 6.2L Boss V8 report a knock or tick right after a cold start. Owners often blame worn cam phasers. The noise usually fades as oil pressure builds and the engine warms, and some owners say it gets worse with mileage. Several things can make this sound on the 6.2L. Owners of the same engine also describe a start-up tick that lasts only until oil reaches the hydraulic valve lifters (lash adjusters). Some owners call that version harmless, and others disagree. Ford also issued a bulletin, TSB 10-25-7, for an engine tick on early 6.2L trucks, including 2011 F-250/F-350 Super Duty trucks built from January 18 to September 7, 2010. That tick came with misfire codes, and its cause was ignition coil or plug-wire installation, worn rocker shaft rollers, or damaged cam lobes. A cold-start noise is not proof of a phaser failure, so the cause needs to be diagnosed before parts are replaced.
Common Symptoms
- Knocking on cold start
- Ticking noise at idle
- Check engine light
- Rough idle when cold
How to Fix
Check first: 1) Scan for stored codes. If there are misfire codes (P0300-P0308 or P0316) along with the tick, follow Ford TSB 10-25-7. Check that the coil-on-plugs and ignition wires are fully seated and reconnect any that are loose. If the noise stays, take off the valve covers and look at the rocker shaft rollers for flat spots or fatigue and the camshaft lobes for damage. Replace the rocker shaft(s) or camshaft(s) as needed. The bulletin says this repair is covered under the New Vehicle Limited and emissions warranties, and it lists labor of 0.7 hr for the coil and wire check up to 7.9 hr for both camshafts. 2) If there are no misfire codes and the noise lasts only until oil pressure comes up, owners report that this is often lifter (lash adjuster) tick. An oil change alone did not stop it for at least one owner. 3) Replace the cam phasers (and their oil-control solenoids) only after a technician confirms that the phasers are the source.
What you need to diagnose it
The repair instructions explicitly call for reading stored codes. Use a scanner that can read the named code families before choosing a repair.The recommended scanner supports these code families; confirm your exact year, model and module coverage before buying.

Reading and clearing the code is DIY work. Module replacement or reprogramming is not — most modules are VIN-programmed, so a new one does nothing until a shop codes it to your car. Check for an open recall or service bulletin before buying anything.

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 $150 to $2,500, depending on the vehicle and root cause.
