What is the P1686 Metering Oil Pump Malfunction?
The P1686 Metering Oil Pump Malfunction is a diagnostic trouble code that indicates a problem with the oil pump in your car’s engine. This pump is responsible for delivering oil to the engine’s moving parts, which helps to lubricate and cool them. When the oil pump malfunctions, it can cause a variety of issues, including poor engine performance, increased engine wear, and even engine failure.
Step-by-Step Guide to Fixing the P1686 Metering Oil Pump Malfunction
Step 1: Check the Oil Level
The first step in fixing the P1686 Metering Oil Pump Malfunction is to check the oil level in your car’s engine. Low oil levels can cause the oil pump to malfunction, so it’s important to make sure that your car has enough oil. To check the oil level, locate the dipstick under the hood of your car and pull it out. Wipe it clean with a rag, reinsert it, and then pull it out again to check the oil level. If the oil level is low, add more oil until it reaches the appropriate level.
Step 2: Inspect the Oil Pump
If the oil level is not the issue, the next step is to inspect the oil pump itself. The oil pump is located inside the engine, so you will need to remove the oil pan to access it. Once you have removed the oil pan, inspect the oil pump for any signs of damage or wear. If the oil pump is damaged or worn, it will need to be replaced.
Step 3: Replace the Oil Pump
If the oil pump is damaged or worn, you will need to replace it. To do this, you will need to remove the old oil pump and install a new one. This can be a complex process, so it’s important to follow the manufacturer’s instructions carefully. Make sure to use the appropriate tools and take your time to ensure that the new oil pump is installed correctly.
Step 4: Test the Engine
Once you have replaced the oil pump, it’s important to test the engine to make sure that the issue has been resolved. Start the engine and listen for any unusual noises or vibrations. Check the oil pressure gauge to make sure that the oil pressure is within the appropriate range. If everything looks good, take your car for a test drive to make sure that it’s running smoothly.
