P0017 on Toyota
Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B
P0017 on Toyota vehicles indicates crankshaft/camshaft position correlation - bank 1 sensor b. Au7o has documented this code across 2 Toyota models — most commonly on Land Cruiser, RAV4. This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other. The computer compares the crankshaft position signal to the camshaft position signal, and when they don't line up within the allowed window, it sets this correlation code. This usually points to mechanical timing being off, most often from a stretched or worn timing chain, a slipped or stuck variable valve timing phaser, or a tensioner problem. You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. Typical repair costs on Toyota range from $600 to $2,500, depending on the specific model and root cause.
Common Causes of P0017
- •Stretched or worn timing chain
- •Worn or failed timing chain tensioner or guides
- •Stuck or faulty variable valve timing (VVT) cam phaser
- •Faulty VVT oil control/solenoid valve
- •Low or dirty engine oil affecting phaser operation
- •Faulty camshaft or crankshaft position sensor
- •Timing chain jumped a tooth or incorrect timing after service
- •Damaged reluctor (tone) ring
P0017 on Toyota by Model
Toyota Land Cruiser(1 issue)
- Timing Belt Tensioner and Water Pump Failure (2UZ-FE)1998-2007
The 2UZ-FE 4.7L V8 uses a timing belt that must be replaced at 90,000-mile intervals. The hydraulic timing belt tensioner and idler pulleys are critical failure points — if the tensioner fails, the timing belt can slip or break, potentially causing valve-to-piston contact on this interference engine. The water pump is driven by the timing belt and commonly leaks at the same mileage interval. Since the labor to access the timing belt is 6-8 hours, all components (belt, tensioner, idler pulleys, water pump) should be replaced together as a comprehensive timing belt service.
Toyota RAV4(1 issue)
- Water Pump Failure/Leak2013-2023
The water pump on the 2.5L 4-cylinder engine can develop leaks or fail, leading to coolant loss and potential overheating. The water pump is driven by the timing chain, so replacement requires significant labor. Some owners experience this around 80,000-120,000 miles.

What does P0017 mean on Toyota?▼
P0017 stands for "Crankshaft/Camshaft Position Correlation - Bank 1 Sensor B." This code means the engine computer has detected that the crankshaft and the Bank 1 'B' camshaft (typically the exhaust camshaft) are out of their proper timing relationship with each other.

You may notice rough running, low power, rattling at startup, or a no-start, and it should be addressed promptly to avoid valve-to-piston contact on some engines. On Toyota specifically, this code is documented across 2 models.
