The 5A family of engines was on the Toyota conveyor from 1987 to 1999 and, in fact, was a variation of the 4A with a reduced volume and the successor to the 3A engines. After the 99th, the 5A-FE modification was inherited by Chinese automakers, which have been replicating it to this day. There were three modifications in the lineup – 5A-F, 5A-FE and 5A-FHE. They all had the same cylinder block (1498 cc), cylinder-piston group (bore 78.7 mm, stroke 77 mm), cylinder head with 22.3° inlet and outlet camber and DOHC 16V. The differences were mainly in the supply and intake systems, as a result of the differing power indicators.

- Burnout of gasoline. The problem can be eliminated by replacing the lambda probe. If soot appears on the candles, black exhaust and vibrations at idle, you need to check the absolute pressure detector.
- Excessive consumption of fuel in the presence of vibrations. It is necessary to rinse the nozzles.
- The revolutions are interrupted and freeze. Correct the idle valve and clean the throttle valve. You also need to adjust its sensor.
- The engine does not start, and there is also an instability of revolutions. Thermal sensor defective.
- Interruption in turnover. It is necessary to clean the throttle-damper module, KXX, candles, injectors and the crankcase ventilation valve.
- The engine suddenly stops. The reason is the fuel pump, distributor and filter.
- Fast oil consumption (more than a liter per thousand km). It is necessary to replace the rings and valve stem seals.
- Engine knocking. Piston pins are defective at high mileage. The valve clearances need to be adjusted.
These and other problems arise due to the high mileage and service life of the 5A motor. Therefore, it is better to buy a copy, the resource of which does not exceed the base 300 thousand km.
