P0076 — Intake Valve Control Solenoid Circuit Low Bank 1

P0076: Intake Valve Control Solenoid Circuit Low Bank 1 — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

Intake Valve Control Solenoid Circuit Low Bank 1. Basic catalogue definition; diagnostic details have not yet been reviewed.

Affected system: Powertrain

Symptoms

  • The engine warning may be present, sometimes with hesitation and reduced acceleration.
  • Uneven running or increased fuel use can accompany the low control-circuit signal.

Possible causes

  • Short to ground, damaged conductors or poor connector contacts on the bank 1 intake valve solenoid circuit.
  • Faulty intake-control solenoid; oil-related VVT operation problems may coexist but do not themselves prove a low electrical signal.

What to check

  • Confirm the low-signal code and examine other actuator or supply-voltage faults.
  • Inspect the bank 1 intake solenoid connector and harness for chafing, corrosion or short circuits.
  • Measure electrical supply, control and solenoid resistance only against the applicable vehicle specifications; also inspect oil condition where relevant.

Also written as: P0076-00, P007600, PO076 (some scan tools add the fault-type byte, e.g. -00).
