P0024 Quick Answer
Bank 2 exhaust cam timing is over-advanced versus commanded, or the actuator response does not match the expected window. Mirror to P0014.
What Does P0024 Mean?
B Camshaft Position – Timing Over-Advanced or System Performance (Bank 2). Bank 2 exhaust cam timing is over-advanced versus commanded, or the actuator response does not match the expected window. Mirror to P0014.
Symptoms
- Cold-start exhaust phaser rattle on bank 2
- Rough idle
- Check engine light
Common Causes
- Stuck bank 2 exhaust VVT phaser
- Blocked oil control solenoid screen
- Sludged oil galleries
- Stretched bank 2 timing chain
- Wrong oil viscosity
- Failed exhaust phaser internal vanes
Diagnosis Steps
You’ll need a scan tool capable of reading live powertrain data, a digital multimeter, and access to the wiring diagram for the specific platform.
- Verify oil level and viscosity.
- Compare bank 2 commanded vs actual exhaust cam phase.
- Inspect VVT solenoid screen.
- Check timing chain stretch.
Possible Fixes
- VVT solenoid + screen service
- Oil change
- Bank 2 timing chain kit
- Phaser replacement
Can I Still Drive With P0024?
The vehicle will usually still drive with P0024 stored, but performance, drivability, or emissions will be degraded. The PCM may inhibit emissions monitors and limit closed-loop fueling adjustments. Drive to a workshop, but don’t ignore the code long-term.
How Serious Is This Code?
P0024 is a moderate-priority fault. It will not prevent the engine from running, but unaddressed it can cascade into related faults or damage downstream components such as the catalytic converter. Address within a few drive cycles.
FAQ
Will P0024 clear itself?
Only if the underlying fault was intermittent and self-corrected. Most root causes are persistent and require physical repair.
Can I clear P0024 without fixing it?
You can clear it with a scan tool, but it will return as soon as the fault condition reappears — typically within one or two drive cycles.
Is P0024 related to other codes?
Often, yes. Adjacent codes in the same circuit or system frequently set together — if P0024 is present, scan for related codes and address them as a group.
