When the starter solenoid is faulty, these problems can arise: The solenoid is an electromagnetic device that transmits electrical current from the battery to the shift fork to engage the starter motor’s drive assembly.Īs a result, the starter drive assembly turns the engine over to start it up. Most starter solenoids are installed directly on top of the starter. The starter solenoid is the device that engages the starter motor. The problem is very common in Corollas from 1990 to 2015.

To fix a piston ring is quite expensive, but the bulk of the cost goes into the labor charges. Before it gets to this stage, it is recommended to get your piston fixed. In this situation, acceleration is impossible and overall performance will be very poor. This is an extreme condition when the piston is totally damaged and the engine loses all its power. Therefore, you need to speed up more to get to the desired speed. A faulty piston could cause the leakage of engine oil into the combustion chamber, leading to excessive thick smoke.Īpart from excessive oil, a faulty piston leads to reduced combustion in the engine, which can cause loss of power. If your vehicle is producing thick and dark gray and blue smoke, this could be a sign of a bad piston.

To address the high oil consumption in some models with the 2AZ engine, Toyota launched the Warranty Enhancement Program ZE7. The number one engine-related issue seems to be excessive oil consumption. The Toyota Corolla is not left out, with owners of different model years complaining about engine oil consumption. Starting from early 2000, there have been complaints about excessive oil consumption in different Toyota models. In this article, we will discuss some of those faults.įollowing our research, we discovered some issues to be more common to Corolla models of various generations.
