why does my Honda CR-V's oil light come on when I turn on the engine

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and the engine is cool.
• Disconnect the battery to avoid any electrical issues.

2. Check and Add Oil

• Sub-steps:
  1. Remove the dipstick and wipe it clean.
  2. Reinsert the dipstick and remove it again to check the oil level.
  3. If the oil level is low, add the appropriate type of oil specified in the owner's manual.
  4. Recheck the oil level after adding oil.

3. Replace Oil Pressure Sending Unit (if faulty)

• Sub-steps:
  1. Locate the oil pressure sending unit (usually near the oil filter).
  2. Disconnect the electrical connector from the sending unit.
  3. Use a socket wrench to remove the old sending unit.
  4. Apply thread sealant to the new sending unit and install it by hand until snug, then torque to manufacturer's specification (usually about 15 ft-lbs).
  5. Reconnect the electrical connector.

4. Change Engine Oil and Filter (if necessary)

• Sub-steps:
  1. Place an oil catch pan under the oil pan.
  2. Remove the oil drain plug using a socket wrench and allow the oil to drain completely.
  3. Replace the oil filter with a new one using an oil filter wrench.
  4. Reinstall the drain plug and torque it to specification (usually about 20 ft-lbs).
  5. Fill the engine with the recommended oil type and quantity.
