P2075 on Opel
Intake Manifold Runner Position Sensor/Switch Circuit High
P2075 on Opel vehicles indicates intake manifold runner position sensor/switch circuit high. Au7o has documented this code across 1 Opel model — most commonly on Zafira. This generic powertrain code sets when the engine control module detects an abnormally high voltage signal on the intake manifold runner position sensor/switch circuit. The intake manifold runner control (IMRC) system uses flaps or runners to optimize airflow at different RPM ranges, and this sensor reports the runner plate position back to the ECM. A high circuit reading indicates the feedback signal is out of its expected range, so the ECM cannot confirm correct runner position. Typical repair costs on Opel range from $50 to $350, depending on the specific model and root cause.
Common Causes of P2075
- •Faulty intake manifold runner position sensor or IMRC actuator
- •Open, shorted-to-power, or corroded wiring/connector in the sensor circuit
- •Sticking, broken, or carbon-fouled intake manifold runner/flap linkage
- •Vacuum leak or failed vacuum solenoid on vacuum-actuated IMRC systems
- •Poor electrical ground or loss of reference voltage to the sensor
- •Failed or misprogrammed ECM/PCM (rare)
P2075 on Opel by Model
Opel Zafira(1 issue)
- 1.9 CDTi Swirl Flap (Drallklappen) Linkage Failure (Z19DTH/Z19DT)2005-2014
The 1.9 CDTi engines in the Zafira B use intake-manifold swirl flaps controlled by a plastic actuator linkage. The linkage rod and bushings wear or break, so the flaps no longer move correctly, triggering limp mode and stored fault codes P2279 (intake air system leak) and/or P2075 (intake manifold runner position sensor/switch). German owners (motor-talk.de, zafira-forum.de) report this commonly around 90,000-150,000 km, often alongside EGR and DPF clogging on the same engine. Left unrepaired, a flap can break off and be ingested by the engine.

What does P2075 mean on Opel?▼
P2075 stands for "Intake Manifold Runner Position Sensor/Switch Circuit High." This generic powertrain code sets when the engine control module detects an abnormally high voltage signal on the intake manifold runner position sensor/switch circuit. The intake manifold runner control (IMRC) system uses flaps or runners to optimize airflow at different RPM ranges, and this sensor reports the runner plate position back to the ECM. A high circuit reading indicates the feedback signal is out of its expected range, so the ECM cannot confirm correct runner position. On Opel specifically, this code is documented across 1 model.
What causes P2075 on Opel vehicles?▼
Common causes on Opel: Faulty intake manifold runner position sensor or IMRC actuator, Open, shorted-to-power, or corroded wiring/connector in the sensor circuit, Sticking, broken, or carbon-fouled intake manifold runner/flap linkage, Vacuum leak or failed vacuum solenoid on vacuum-actuated IMRC systems, Poor electrical ground or loss of reference voltage to the sensor. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P2075 on a Opel?▼
Repair costs on Opel range from $50 to $350, depending on the specific model and root cause.
