P0009

Engine Position System Performance (Bank 2)

Severevariable valve

Overview

The P0009 diagnostic trouble code indicates a engine position system performance (bank 2) condition. This code relates to the variable valve timing (VVT) system, which adjusts camshaft timing for optimal performance across the engine's RPM range. VVT issues often stem from oil quality or flow problems and can cause rough idle, poor performance, and decreased fuel economy.

Symptoms

  • Ticking or clicking noise from engine
  • Engine stalling at idle
  • Poor fuel economy
  • Reduced engine performance

Common Causes

  • Worn timing chain or stretched chain
  • Clogged oil passages to VVT system
  • Faulty VVT solenoid/actuator (oil control valve)
  • Dirty or low engine oil

Diagnosis Steps

  1. 1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
  2. 2Check engine oil level and condition; change oil if dirty or incorrect viscosity
  3. 3Test the VVT solenoid (oil control valve) with a multimeter
  4. 4Inspect the VVT solenoid screen/filter for debris or sludge
  5. 5Monitor camshaft position sensor data using scan tool live data
