P0017 — Instant Answer
Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor B)
Severity: HIGH SEVERITY
Meaning: The crankshaft and exhaust camshaft positions on bank 1 are out of sync. Similar to P0016 but for the exhaust cam. Often points to timing chain issues.
Safe to drive? NO if CEL is flashing. YES with caution if solid, but repair this week.
Estimated repair cost: $50 - $1,500
Most common causes:
- 1. Worn timing chain (35-45% of cases)

Related Codes
The crankshaft and intake camshaft positions are not synchronized on bank 1. This indicates a timing problem that can cause rough running or no-start conditions.
The exhaust camshaft on bank 1 is more advanced than the ECM expects. Usually caused by sludged oil blocking the VVT actuator or a stuck solenoid.
The ECM detected a fault in the exhaust camshaft VVT solenoid circuit on bank 1. This solenoid controls exhaust valve timing for optimal performance and emissions.
