how to troubleshoot a Honda Accord that won’t shift out of park

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the ignition is off.
• Gather necessary tools and parts.

2. Inspect Brake Light Switch

• Locate the brake light switch, usually mounted above the brake pedal.
• Disconnect the wiring harness from the switch.
• Test the switch with a multimeter for continuity when the brake pedal is pressed.
• If defective, replace the brake light switch (part number may vary by model year).

3. Check Shift Interlock Solenoid

• Remove the center console cover to access the shift interlock solenoid.
• Disconnect the wiring harness from the solenoid.
• Test the solenoid’s resistance with a multimeter; replace if out of specification.
• If necessary, lubricate the solenoid mechanism to ensure free movement.

4. Inspect Shift Linkage

• Access the transmission linkage under the vehicle.
• Check for any signs of wear, binding, or damage.
• Adjust or replace the shift linkage as needed, ensuring it is properly aligned.

5. Transmission Fluid Check

• Remove the transmission dipstick, wipe it clean, and reinsert it to check fluid level.
• If low, add the manufacturer-recommended transmission fluid (e.g., Honda ATF-Z1 or equivalent).
• If fluid is dark or has a burnt smell, consider a transmission fluid change.
