During your drive, if your car dashboard displays abnormal oil pressure, there's no need to panic. The abnormal oil pressure typically recovers after about 10 seconds. This situation usually indicates an issue with the fuel injection system's fuel pressure. Specifically, it could be due to a malfunctioning fuel pump, deteriorating or leaking engine oil, or insufficient oil.
In such a scenario, it's crucial to take immediate action to prevent further damage to the engine. First, safely park the vehicle and turn off the engine. Then, check if the engine oil is low. If the oil level is sufficient and the abnormal oil pressure persists, do not idle the engine, and it's advisable to seek assistance from an authorized service center (4S store) promptly.
Continuing to drive under these conditions could lead to severe consequences. Increased internal engine wear may occur, and in extreme cases, problems such as bearing seizure and piston scuffing may manifest. To address this issue, substantial repairs or even engine replacement may be necessary. Clearly, such costs are unacceptable for vehicle owners.
How can you determine if the oil pump is faulty? There are some indicators to help you make this assessment.
Firstly, when starting the vehicle, if you turn the key to the ignition position and the vehicle fails to start after a very short period, it's likely that the oil pump is experiencing issues. Secondly, if you feel a lack of power during acceleration and experience hesitation when rapidly applying the throttle. Additionally, corresponding warning lights may illuminate on the dashboard, and you might hear a buzzing noise while driving.
