P0024 on Toyota vehicles
Exhaust Cam Over-Advanced (Bank 2, VVT) — what it means on a Toyota, whether it's safe to drive, and the fixes by model and year.
P0024 on a Toyota means exhaust cam over-advanced (bank 2, vvt). Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is stuck or sludged bank 2 exhaust-side vvt oil control valve (typically $100–$450). Pick your Toyota model below for its known failure patterns, recalls, and TSBs.
What does P0024 mean on a Toyota?
P0024 is set when the engine control module commands the Bank 2 exhaust camshaft ("B" camshaft) to a position and the actual cam position reads too far advanced, or the phaser fails to track the command within tolerance. It is the Bank 2 counterpart of P0014. Bank 2 is the cylinder bank that does NOT contain cylinder number 1, so this code only appears on V6, V8, V10, V12, and flat / boxer engines. The causes are the familiar variable valve timing set: a stuck oil control valve, oil that cannot do its job, or a failing phaser.
P0024 is a standardized OBD-II code, so its definition is the same on every Toyota. What differs by model and engine is which cause is most likely — pick your Toyota model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Toyota with P0024?
In most cases a Toyota stays drivable for short trips with P0024 active, but diagnose and repair it promptly. This is a high-severity code — ignoring it can lead to further damage or a failed emissions test. Exact tolerance depends on the model and engine.
What causes P0024 on a Toyota?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Stuck or sludged Bank 2 exhaust-side VVT oil control valve | Most common | $100–$450 |
| Low engine oil level or pressure starving the Bank 2 exhaust phaser | Most common | $50–$200 |
| Sludged oil passages from skipped oil changes | Common | $100–$600 |
| Failed Bank 2 exhaust cam phaser / VVT actuator | Common | $600–$1,800 |
| Stretched timing chain affecting Bank 2 exhaust cam position | Occasional | $800–$3,000 |
| Damaged Bank 2 exhaust cam sensor wiring or connector | Occasional | $80–$350 |
| Failed Bank 2 exhaust cam position sensor | Occasional | $100–$400 |
Repair costs are typical US ranges and vary by Toyota model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.

What are the symptoms of P0024 on a Toyota?
Check Engine Light is illuminated. Rough idle, often worse when the engine is hot. Reduced low-end torque and slow throttle response. Possible stalling at low RPM. Increased emissions at idle. Slight reduction in fuel economy. Cold-start rattle from the cam area
