Official description

Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor B

Laymans terms

This code means that the car's computer thinks the engine parts aren't lined up correctly. It's like if the gears in a clock were out of sync, so the clock wouldn't tell time properly.

Explanation

The engine control module (ECM) detects that the crankshaft and camshaft are not aligned properly, which can affect engine timing.

Technical description

P0017 indicates a misalignment between the crankshaft and camshaft positions as detected by the ECM. This misalignment can cause poor engine performance and increased emissions.

Diagnosis steps

• Use an OBD-II scanner to confirm the P0017 code

• Inspect the timing chain or belt for wear or damage

• Check the camshaft and crankshaft position sensors

Repair procedures

• Replace the timing chain or belt if necessary

• Replace faulty camshaft or crankshaft position sensors

• Adjust or replace the timing chain or belt tensioner

Tools required

• OBD-II scanner

• Socket set

• Timing light

Estimated repair cost
