B Camshaft Profile Actuator C Control Circuit High (Bank 1)

B Camshaft Profile Actuator C Control Circuit High (Bank 1): the control-circuit voltage is above the expected range. This relates to engine timing; a fault can cause rough running, a no-start, or timing errors.

Affected components

  • Camshaft position actuator

Common causes

  • High likelihood: Short to B+
  • Low likelihood: Connector pins corroded - high contact resistance
  • Low likelihood: Supply wire pinched against B+ source

Possible symptoms

  • Check engine light on
  • Power loss especially in mid-rpm range
  • Possible rough idle or stalling
  • Increased fuel consumption

Diagnostic notes

  • The malfunction indicator lamp may illuminate
  • This code can affect emissions
