The sensors on a 2017 Honda Civic are distributed across the vehicle, with key safety features relying on a front radar sensor and a forward camera for driver-assist systems, plus wheel-speed, tire-pressure, engine, and cabin sensors throughout the car. Exact placements can vary by trim and equipment such as Honda Sensing.
Overview of Civic sensors
Below is a quick inventory of the main sensing hardware and where you typically find it on the 2017 Civic.
- Front radar sensor for Honda Sensing, usually mounted in the center of or behind the lower portion of the front bumper to feed adaptive cruise control and collision mitigation
- Forward-facing camera for Lane Keeping Assist, Lane Departure Warning, and related features, located behind the windshield near the rearview mirror
- Ultrasonic parking sensors (if equipped), embedded in the front and/or rear bumper to help detect obstacles while parking
- Wheel-speed sensors at each wheel hub, used by ABS, traction control, and stability control systems
- Tire Pressure Monitoring System (TPMS) sensors in each tire valve stem to monitor tire inflation
These sensors form the core of the Civic’s safety, stability, and parking systems. If your trim includes Honda Sensing, the radar and camera are the primary ADAS sensors, complemented by wheel-speed and TPMS data to support overall vehicle dynamics.
Engine, emissions, and powertrain sensors
Next, the Civic’s engine and exhaust management rely on a suite of sensors that monitor performance, fuel delivery, and emissions.
- Crankshaft position sensor and camshaft position sensor, located in the engine to track timing for ignition and fuel injection
- Oxygen sensors (upstream and downstream of the catalytic converter) to monitor exhaust composition and help control the catalytic converter
- Mass Air Flow (MAF) sensor or Manifold Absolute Pressure (MAP) sensor in the intake system to gauge air entering the engine
- Intake air temperature sensor (and, in some designs, a separate manifold air temperature sensor)
- Engine coolant temperature sensor to inform the ECU about engine warm-up and operating temperature
- Fuel pressure sensor to monitor fuel delivery and assist with fueling control
- Oil pressure sensor or oil pressure switch to monitor lubrication health in some engines
These sensors feed the engine control unit (ECU) and the onboard diagnostics system, enabling efficient fuel use, appropriate ignition timing, and emissions compliance.
Cabin, safety, and environment sensors
Cabin comfort and occupant safety also rely on several sensors scattered through the vehicle’s interior and structure.
- Occupant Classification System (OCS) sensor under the front passenger seat cushion to determine airbag deployment intent based on weight
- Airbag crash sensors located at strategic points in the dash and sides of the vehicle to detect collisions and trigger airbags
- Steering angle sensor in the steering column to assist stability control and lane-keeping functions
- Ambient outside air temperature sensor, typically near the front of the vehicle or bumper, used by climate control and safety systems
- Interior climate sensors used by the HVAC system to maintain comfortable cabin conditions (often integrated with the dash electronics)
These sensors contribute to occupant protection, comfort, and environmental awareness inside the Civic, as well as safety features that respond to road conditions and driver input.
Where to locate or service sensors
Most sensors are sealed and designed for long service life, but some are accessible for inspection or diagnostics during routine maintenance or airbag/seat servicing. If you’re diagnosing a sensor-related warning light or a malfunction, refer to the owner’s manual or consult a qualified technician, as some components (like airbags) require special handling.
Summary
The 2017 Honda Civic distributes sensors across three broad domains: driver-assist safety (front radar and windshield camera, plus parking aids where equipped), engine and emissions (crank/cam sensors, O2 sensors, MAF/MAP, temperature and pressure sensors), and cabin/safety systems (occupant detection, airbags, steering sensors, and ambient climate sensors). Trim level and options like Honda Sensing influence which sensors are present and where they’re located. For precise locations and service guidance, consult the owner’s manual or a Honda-certified technician.
