Toyota sub-warhead car 2TZ model engine, stepped on the throttle pedal, the engine speed is slightly improved, the oil pressure warning light that light, relax the pedal that is back to normal.
A Toyota bullet warhead, engine model 2TZ, in the overhaul after the running process, the idle when everything is normal, but when the throttle pedal, the engine speed is slightly improved, the oil pressure warning light that light, relax the pedal that is restored normal.
According to the above phenomenon, check the oil, the line, both are normal; oil pump installed before the test, the oil supply, normal; and start the engine with the engine to check the work of the oil pressure, but also normal; Sensor, fault still. Therefore, the suspected filter blockage, idling, the need for less oil, clogging part does not affect the establishment of oil pressure; but high speed, the need for large oil, filter area reduced, the oil is not timely, affecting the oil pressure. But the engine overhaul parts were thoroughly cleaned, there can be no more dirt, open the oil pan check, the collector no exception. After repeated careful examination, suddenly found a bottom of the bottom of the oil to the raised parts, a closer look at the components of the filter, and then its original condition, installed after the test, troubleshooting.
The reason is that the original raised part of the filter to the location of the space to reduce, in addition to the amount of oil is small, the engine idling oil pump oil less, this site does not affect the establishment of oil; when high speed, oil pump The oil is large, the oil in the parts of the filter is quickly sucked up, and the oil is added at this point. As the bulging site is caused, the oil supply is not timely and the oil quantity of the oil pump does not match the engine condition. Resulting in reduced oil pressure, oil lamp light.
