P2013 Intake Manifold Runner Control Circuit High (Bank 2)

P2013 points to a control line of the bank 2 flap actuator that sits too high, i.e. a short to battery voltage or an actuator whose winding has shorted so the driver sees supply where it expects a load. No manufacturer documents P2013 publicly. The logic can be taken from bank 1, where GM checks P2010 as a resistance to supply below 0.5 Ω and Saab's 2010 9-5 diesel uses it for the swirl solenoid control shorted to voltage. CARB requires circuit faults of such output components to be watched continuously, and runner systems are named among the outputs to monitor. Ford's V engines report bank 2 only as P2011, so a P2013 is more likely on other makes with one actuator per bank. Checking the wiring with the actuator unplugged usually separates harness from actuator. The flaps on that bank then stay in their rest position.

Likely causes

Bank 2 control wire shorted to a supply wire
Shorted winding in the bank 2 actuator
Engine control module output stage faulty

Symptoms

  • Malfunction indicator lamp on
  • Bank 2 flaps no longer switch
