why does my Honda CR-V Fifth Generation (2017-2022) have low oil pressure warning

Solution

1. Preparation

• Gather tools and materials: mechanic’s gloves, wrench set, oil pressure gauge, new oil filter, engine oil, rags for cleaning.
• Ensure the vehicle is parked on a level surface and the engine is off and cool.

2. Check and Top Off Engine Oil

• Remove the dipstick and wipe it clean.
• Insert the dipstick back into the tube, remove it again, and check the oil level.
• If low, add the recommended engine oil (SAE 0W-20 or as specified in the owner’s manual) until the correct level is reached.

3. Replace the Oil Filter

• Place a drain pan under the engine to catch any oil spills.
• Using a wrench, remove the old oil filter. Ensure the rubber O-ring comes off with it.
• Apply a small amount of new oil to the O-ring of the new filter and install it hand-tight.
• Recheck oil level after replacing the filter.

4. Test Oil Pressure

• Remove the oil pressure switch located on the engine block.
• Install the mechanical oil pressure gauge in place of the oil pressure switch.
• Start the engine and check the oil pressure reading; it should be within manufacturer specifications (typically 20-60 PSI at idle).
• If pressure is low, the oil pump may need replacement.

5. Inspect the Oil Pump (if necessary)

• If the oil pressure is low, drain the engine oil and remove the oil pan.
• Inspect the oil pump for wear, clogs, or damage.
• Replace the oil pump if needed, following manufacturer specifications for installation.
