Symptoms

  • The Check Engine light comes on during a cold start, but may go off after warming up.
  • Unstable engine operation when cold - shaking, unstable speed
  • Increased fuel consumption when warming up
  • Hesitation or jerking when accelerating on a cold engine
  • It is possible to warm up the engine to operating temperature for a longer period of time

Causes

  • Thickened or thinned engine oil (viscosity mismatch for a given engine)
  • Contamination of the phase control solenoid valve (VVT solenoid) of bank 1
  • Camshaft A phase shifter (VVT clutch) of bank 1 camshaft A is worn or dirty
  • Low oil pressure during cold start (worn oil pump, clogged strainer)
  • Bank 1 Camshaft Position Sensor Malfunction

How to Fix

  1. Check the level and quality of the engine oil - make sure the viscosity corresponds to the manufacturer’s recommendations for the given climate
  2. Read frozen frame codes and data; pay attention to the coolant temperature at the moment the code is recorded
  3. Check the operation of the phase control valve (solenoid) of bank 1: apply a control signal and listen for a characteristic click
  4. Wash the phase control valve with a special cleaner or replace it if clogged.
  5. Check the oil pressure during a cold start with a pressure gauge
  6. Flush the VVT ​​system and change the oil and filter; if necessary, replace the phase shifter
