P0017 on Toyota by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Squealing or chirping noise from timing belt area
- Coolant leak from water pump weep hole
- Engine approaching or past 90,000 miles without timing belt service
- Timing belt showing cracks or wear on inspection
- Rough idle or engine timing issues
How to Fix
Perform a comprehensive timing belt service every 90,000 miles, replacing the timing belt, hydraulic tensioner, both idler pulleys, and water pump together. A complete timing belt kit with water pump costs $250-$500 for parts. Labor is 6-8 hours ($600-$1,200) due to the tight engine bay and need to remove accessories for access. Use OEM Toyota or Aisin (OEM supplier) components only — aftermarket timing belts and tensioners have higher failure rates on this engine. Always replace the thermostat and coolant while the system is apart. Total cost: $1,000-$1,800 at an independent shop, $1,500-$2,500 at the dealer.

Owner tips & cautions
- WarningDo NOT skip or delay the 90,000-mile timing belt service. The 2UZ-FE is an interference engine — if the belt breaks, valves hit pistons and you are looking at a $5,000-$8,000 engine rebuild. This is the single most important maintenance item on the 100-series.
- TipAlways replace the water pump with the timing belt. The pump costs $60-$100 extra and the labor is already done. A water pump failure between timing belt services means paying for the full labor again.

Frequently asked questions
What does P0017 mean on a 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. 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. On Toyota it is documented across 1 model: Land Cruiser.
What are the most common causes of P0017?
The most common causes of P0017 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0017 on a Toyota?
Published repair estimates on Toyota range from $1,000 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.
