The sensors in a Honda Accord are spread across the vehicle—from the engine bay to the wheels, and from the bumper to the cabin. They support everything from engine management and braking to safety and driver-assistance features.
The following guide outlines common sensor locations by system. Note that exact placements can vary by model year and trim; always check the specific service manual for your car.
Engine management sensors
These sensors monitor the engine’s air, fuel, temperature, and position to help the ECU optimize performance and emissions. They are primarily located in the engine bay.
- Mass Air Flow (MAF) sensor — on the intake air tube between the air filter box and the throttle body.
- Intake Air Temperature (IAT) sensor — often mounted on the air intake duct or integrated with the MAF sensor.
- Manifold Absolute Pressure (MAP) sensor — on or near the intake manifold.
- Throttle Position Sensor (TPS) — on the throttle body, measuring throttle plate angle.
- Coolant Temperature Sensor (ECT) — located in the cylinder head or near the thermostat housing.
- Oxygen (O2) sensors — upstream sensor(s) in the exhaust manifold and downstream sensor(s) after the catalytic converter.
- Crankshaft Position Sensor — mounted near the crankshaft pulley or on the engine block.
- Camshaft Position Sensor — located near the camshaft(s) in the engine head.
- Knock Sensor — embedded in the engine block or cylinder head, detecting knocking.
- Fuel Rail Pressure Sensor — attached to the fuel rail (in some configurations) to monitor fuel pressure.
These sensors feed data to the engine control module (ECU) to regulate air-fuel mixture, ignition timing, and emissions control.
Chassis and drivetrain sensors
These sensors monitor vehicle dynamics and the drivetrain’s state, contributing to stability control, shifting behavior, and overall driveability.
- Steering Angle Sensor — located in the steering column, used by stability control and advanced driver-assistance systems (ADAS).
- Vehicle Speed Sensor (VSS) — mounted on the transmission or output shaft, providing road speed data.
- Transmission Fluid Temperature Sensor — inside the transmission pan or housing, monitoring transmission temperature.
- Gear/Shift Position Sensor — part of the transmission or shifter assembly, detecting gear selection.
These sensors help the powertrain and stability systems respond correctly to driving conditions and gear selection.
Brakes, ABS and tire sensors
Braking performance and tire status rely on sensors at the wheels and on the tires themselves. These are typically located at or near the wheel hubs and within the tire assemblies.
- Wheel Speed Sensors (ABS) — mounted at each wheel hub, measuring rotor speed for ABS/ESC functions.
- Tire Pressure Monitoring System (TPMS) Sensors — located inside each tire valve stem (on most models) or within the wheel assembly, monitoring tire pressure.
These sensors enable anti-lock braking, traction control, and proactive tire maintenance alerts.
Safety and driver-assistance sensors
Safety features in Honda Sensing and other driver-assistance systems rely on sensors placed at the front, sides, and interior of the vehicle.
- Front Radar Sensor (millimeter-wave) — usually behind the front bumper, part of collision mitigation and adaptive cruise control.
- Forward-Facing Camera — mounted behind the windshield near the rearview mirror, used for lane-keeping assist and traffic sign recognition.
- Parking Sensors — rear and sometimes front bumper sensors in trims that offer parking assist.
- Airbag Crash Sensors — located in front rails and other crash zones to detect impacts and deploy airbags.
- Side Airbag Sensors — located in doors or near seats to monitor side-impact conditions.
- Seat Occupancy Sensor — cushion/seat pad in the front passenger seat to determine occupant weight for airbag deployment.
These sensors underpin collision avoidance, safe airbag deployment, and parking assistance features across compatible trims.
Cabin and environmental sensors
Cabin climate control, comfort features, and weather adaptation rely on sensors placed inside or near the HVAC system and exterior ambient areas.
- Rain Sensor — mounted behind the windshield near the top center to control automatic wipers.
- Humidity Sensor — part of the HVAC system, aiding climate control and dehumidification.
- Ambient Temperature Sensor — located in the front of the vehicle, reporting outside temperature for HVAC and displays.
- Interior Temperature Sensors — monitor cabin air temperature for automatic climate control.
These sensors help maintain comfort and system responsiveness under varying weather and occupancy conditions.
Summary
In a Honda Accord, sensors are dispersed to support engine performance, drivetrain management, braking and tire safety, airbags and driver-assistance systems, and cabin comfort. While locations listed here cover common placements across many 2018–2024 Accords, trims and model years can differ. For exact locations and service procedures, consult the owner’s manual or a Honda service manual for your specific year and trim.

How many sensors does a Honda Accord have?
How many oxygen sensors does my 2014-2022 Accord have? It depends on your engine. Four-cylinder models typically have two sensors: one upstream and one downstream. V6 models usually have four sensors: two upstream and two downstream, one pair for each bank of cylinders.
