How does a Engine Oil Level Sensor work?

An engine oil level sensor uses a float switch inside the oil pan that is normally off when the engine oil level is within an acceptable range. When the level drops, the float drops and the switch turns on, sending a signal to the Powertrain Control Module (PCM) which, in turn, lights up the oil level warning lamp on the dashboard. The PCM monitors the oil level and engine temperature when the engine is in operation.

What are the symptoms of a bad Engine Oil Level Sensor?

A bad oil level sensor may cause a false reading of the engine oil level. The oil level warning light may illuminate even when the oil level (checked manually) is within an acceptable range. The warning light may also come on and off intermittently if the sensor is faulty. An error code may be sent to the PCM and a check engine light may come on the dashboard as well if the sensor is bad.

Can I drive with a bad Engine Oil Level Sensor?

A vehicle with a bad oil level sensor can be driven if it is not causing additional problems because of false signals sent to the PCM. The sensor is not critical to basic engine function, however it is an important safeguard and should be changed as soon as possible.

How often do Engine Oil Level Sensors need replacement?

The engine oil level sensor does not have a scheduled maintenance or replacement schedule and should last the lifetime of the vehicle. However, the sensor is exposed to harsh conditions and may be prone to wear and premature failure.

How are Engine Oil Level Sensors replaced?

To replace a bad engine oil level sensor, a technician will lift and support the vehicle, drain the oil, remove the bad sensor, and install a new one. The oil (and filter) are replaced and the vehicle is lowered to the ground. The technician will start the vehicle to make sure that the sensor is operating properly and that there are no engine oil leaks.

RepairPal Recommendations for Engine Oil Level Sensor issues

When the engine is first started, the oil level warning light, along with the other warning lights, will illuminate on the dashboard momentarily. This is a normal operation as the vehicle's computers go through a diagnostic check of the vehicle systems. If the oil level warning light remains lit, the oil level should be manually checked with the dipstick. If the oil level is within the acceptable range on the dipstick, but the warning light is on, there may be a problem with the sensor. If the oil level is low, oil should be added to the engine immediately. In either case, the vehicle should be inspected by a qualified technician at a trusted repair facility to determine what the cause of the problem might be, whether a faulty sensor or an oil consumption problem.

What to look out for when dealing with Engine Oil Level Sensor issues

A low oil level is no small problem. If caught early, damage to the engine may be prevented. However, low oil is not merely a problem, it is a symptom. A low oil level can be caused by an oil leak in one or more of several places in the engine. Alternately, a low oil level can be caused by oil that has been neglected through infrequent oil changes, leading to engine oil sludge and clogged engine components. If the oil level warning light comes on, the oil level should be checked and topped off if it is found to be low. The cause of the low oil condition should be investigated as soon as possible. If the oil level is considerably low - below the "low" level on the dipstick - the vehicle should not be driven until oil has been added.

Can I replace the Engine Oil Level Sensor myself?

Because it is necessary to lift and support a vehicle in order to replace an engine oil level sensor, the repair should only be done by someone with an intermediate level of DIY experience. Otherwise, it is best left to a repair professional.
