I will be testing the Intake and Exhaust Camshaft Actuator Solenoid Valves in this video. The vehicle is a 2012 Buick Verano with a 2.4L Ecotec engine. These solenoids are high failure items on this particular engine.

Engine Performance Diagnostics chapter 3

Topics discussed


  • check engine light
  • P0010 (P0011, P0013, P0014 are related codes)

fix 50

  • replace faulty intake and exhaust camshaft actuator solenoid valves

test shown

  • how to identify circuit design using a voltmeter
  • how to identify the control wire
  • how to use a scan tool and command the solenoids on
  • how to identify current flow is taking place
  • how to measure resistance of the solenoids

Tools used

  • scan tool
  • digital multimeter
  • lab scope (not necessary to troubleshoot this problem but it helps)
