P2076 — Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Range/Performance Bank 1

Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Range/Performance Bank 1. Basic catalogue definition; diagnostic details have not yet been reviewed.

Affected system: Powertrain

Symptoms

• The engine warning light may come on.
• There may be hesitation or weak acceleration, although some vehicles show no obvious drivability symptoms.

Possible causes

• The bank-1 intake-manifold tuning valve position sensor may report an implausible position.
• Loose or damaged sensor wiring and connectors can affect its reading.
• A sticking tuning-valve mechanism or actuator can also produce a position mismatch.

What to check

• Confirm P2076 and inspect the position-sensor and tuning-valve connectors for damage or corrosion.
• Observe available position data while commanding the valve with a compatible scan tool.
• Check mechanical freedom and the sensor circuit against service data before replacing components.

Also written as: P2076-00, P207600 (some scan tools add the fault-type byte, e.g. -00).
