P2675 — Air Cleaner Inlet Control Circuit/Open
OBD2 code P2675 flags a problem with the sensor and actuator circuits (air cleaner inlet control circuit/open). The car is usually drivable while you plan the repair. Common culprits: corroded, loose or damaged connector, blown fuse feeding the circuit, poor ground connection.
powertrain (engine/transmission)
Is it safe to drive?
Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm P2675 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the air cleaner inlet control circuit/open for damage, corrosion, chafing or poor contact.
- Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
- Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2675 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for P2675 (parts and labor, USD, independent shop rates): Control module repair: $300–$1,000; Repair wiring or connectors: $80–$250; Replace the faulty sensor or actuator: $150–$500. Overall, fixing P2675 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
What is the most common cause of P2675?
The most common causes are: corroded, loose or damaged connector, blown fuse feeding the circuit, poor ground connection.
What does OBD2 code P2675 mean?
OBD2 code P2675 flags a problem with the sensor and actuator circuits (air cleaner inlet control circuit/open). The car is usually drivable while you plan the repair. Common culprits: corroded, loose or damaged connector, blown fuse feeding the circuit, poor ground connection.
What are the symptoms of P2675?
Drivers most often notice: possible limp mode depending on the affected component, Check Engine Light on, increased fuel consumption in some cases, the affected system operates intermittently or not at all.
How much does it cost to fix P2675?
Control module repair — $300–$1,000; Repair wiring or connectors — $80–$250; Replace the faulty sensor or actuator — $150–$500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.
How do I diagnose P2675 myself?
Start with a scan: confirm P2675, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the sensor and actuator circuits, and verify the suspect component against live data before buying parts.
What does P2675 mean?
The engine control module sets P2675 when it detects a fault in the sensor and actuator circuits. In practical terms: air cleaner inlet control circuit/open. The code belongs to the powertrain (engine/transmission) group of OBD2 codes.
The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2675 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.
What causes P2675?
- poor ground connection
- open or shorted wiring in the circuit
- control module driver fault
- faulty sensor or actuator of the affected circuit
- corroded, loose or damaged connector
