Toyota bullet car 2TZ model engine when the throttle pedal is depressed, the slightest increase engine speed, oil pressure warning light that is lit, relaxing pedal returned to normal.
Bullet a Toyota car, engine type 2TZ, after the overhaul running-in process, everything is normal at idle, but when depressing the throttle pedal, the engine speed the slightest increase, oil pressure warning light that is lit, relaxing pedal is restored normal.
According to the above symptoms, check the oil level, line, both of which were normal; pump before digimaster 3 update installation, test the fuel supply, normal; driven by the engine with the starter and check the oil pressure is normal; replace the oil pressure sensor fault persists. Therefore, the suspect set the filter clogging, when idling, need less oil, clogged section does not affect the oil pressure build; but at high speed, the need to fuel large set of filters to reduce the area of the oil is not timely, the impact of the oil. But when the engine overhaul parts are carried out a thorough cleaning, there can be no more dirt, open sump check strainer no exception. After repeated careful examination, suddenly found the oil pan to the inside bottom there is a raised position, a closer look at what are the parts strainer, then fix it undisturbed, after installed for testing, troubleshooting a.
The reason for the raised portion of the original set of filters that make parts of the reduced toyota intelligent tester 2 space, in addition to deposit less fuel, engine idling time to pump less oil, this part does not affect the oil pressure build; When the high-speed, oil pump output big oil, set on the site of the oil filter quickly be pumped oil elsewhere to supplement here, due to the raised part due so that the oil supply is not timely, the amount of oil pump and engine operating conditions do not match, so resulting in lower oil pressure, machine oil lamps lit.
