why aren't my Honda Accord 10th Generation (2018-2022) parking sensors working

Solution

1. Preparation

• Tools Needed: OBD-II scanner, multimeter, socket set, cleaning supplies (e.g., microfiber cloth, mild detergent).
• Disconnect the vehicle battery to prevent electrical shock.
• Ensure the vehicle is parked on a level surface with the engine off.

2. Inspect Wiring and Connectors

• Remove the rear bumper cover if necessary to access the wiring harness.
• Visually inspect the wiring for frays or cuts.
• Check the connectors for corrosion or loose connections; reseat any that appear disconnected.

3. Check and Replace Fuses

• Locate the fuse box (usually found under the dash or in the engine compartment).
• Identify the fuse for the parking sensors using the diagram on the fuse box cover.
• Remove the fuse and inspect it for continuity using a multimeter; replace if blown, using the same amperage.

4. Clean Parking Sensors

• Locate each parking sensor on the vehicle's bumper.
• Use a mild detergent and a microfiber cloth to clean the sensor lenses.
• Ensure no obstructions are present and that sensors are securely mounted.

5. Test Each Sensor

• Connect the multimeter to the parking sensor wiring harness.
• Check for voltage when the vehicle is in reverse; if no voltage, trace back to the control module.
• If the sensor is faulty, remove it by unscrewing or unclipping from the mounting bracket and replace it.

6. Reassemble and Reconnect Battery

• If any components were removed (e.g., bumper), reassemble them carefully.
• Reconnect the battery and ensure all connections are secure.
• Clear any error codes using the OBD-II scanner.
