Learn how to diagnose and fix knocking noise during acceleration in Honda Civic 10th Generation. Step-by-step guide with diagnostic procedures and repair instructions.

Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems
•Allow the engine to cool before opening the oil drain plug

Symptoms

•Knocking noise from the engine bay during acceleration
•Loss of power or sluggish acceleration
•Possible vibration felt through the steering wheel or chassis
•Increased engine noise at certain RPMs
•Check engine light may be illuminated

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to check for any diagnostic trouble codes (DTCs)
2
Inspect the engine oil level and condition; low or dirty oil can cause knocking
3
Check for any loose or damaged components in the engine bay, including mounts and brackets
4
Test drive the vehicle to replicate the knocking noise and identify the specific RPM range when it occurs
5
Inspect the drive shafts and CV joints for wear or damage
6
Evaluate the condition of the motor mounts for signs of deterioration or failure

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to ensure safety while working on electrical components.
Raise the vehicle using jack stands for access to the undercarriage if needed.

2. Engine Oil Change (if oil condition is poor)

Tools Required: Socket set, oil filter wrench, oil catch pan.
Drain the old engine oil by removing the oil drain plug; allow it to fully drain into the catch pan.
Replace the oil filter using the oil filter wrench, ensuring the old rubber O-ring is removed.
Reinstall the drain plug with a torque specification of 30 lb-ft.
Fill the engine with the appropriate grade of oil (e.g., 0W-20) as specified in the owner’s manual.

3. Inspect and Replace Motor Mounts (if damaged)

Tools Required: Socket set, torque wrench, pry bar.
Remove the bolts securing the damaged motor mount using the socket set.
Use the pry bar to carefully lift the engine to relieve pressure on the mount.
Install the new motor mount and tighten the bolts to the manufacturer’s torque specifications.
Repeat for each motor mount that shows signs of wear.

4. Inspect Drive Shafts and CV Joints

Tools Required: Jack stands, socket set, torque wrench.
Raise the vehicle and remove the wheels for access to the drive shafts.
Inspect the CV joints for any tears in the rubber boots or signs of grease leakage.
Replace any damaged drive shafts or CV joints as needed, ensuring all bolts are torqued to specifications.
