P0024 on Ford: How to Diagnose & Fix
Exhaust Camshaft Position Timing - Over-Advanced (Bank 2)
3 Ford models · 3 documented issues · 1 critical · $500-$2,500 repair
P0024 on Ford by model: symptoms, diagnosis and fix
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.

The 4.0L SOHC V6 cam phasers develop a loud rattle on cold startup that can persist for 30+ seconds. The phaser internal mechanism wears, causing timing chain slack and potential timing issues.
Common Symptoms
- Loud rattle on cold start
- Rattling for 30+ seconds
- Check engine light
- Reduced power
How to Fix
Replace the cam phasers, timing chain, tensioners, and guides as a complete kit. This is a labor-intensive repair requiring removal of the front of the engine. Use updated Ford phasers.

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 on a Ford?
P0024 stands for "Exhaust Camshaft Position Timing - Over-Advanced (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. On Ford it is documented across 3 models: F-350, Explorer Sport Trac, F-250.
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 on a Ford?
Published repair estimates on Ford range from $500 to $2,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
