b) Check fuel level in fuel tank and fuel filter;
c) Check whether the exhaust system is blocked, e.g., three-way catalytic converter is blocked due to burn
fuel or break-up;
d) Inspect fuel path pressure and nozzle;
e) Check whether the fault indicator blinks and whether the reason is that only one cylinder can normally
ignite.
16.4.3.8 Symptom - Slight sparking
Check whether the spark plug clearance is in line with the specification ( 0.6 ~ 0.8 mm)
16.4.3.9 Symptom - Fault indicator blinks but fault code is inconsistent with
actual fault
The fault may be caused by loose connection of ground wire of the system; re-connect the ground wire, then
disconnect the power cord of the accumulator for 3 minutes and re-connect the cord, and start the engine.
16.4.3.10 Symptom - Abnormally high fuel consumption
a) Inspect the oxygen sensors of two cylinders are installed in place; if loose, the oxygen sensor erroneously
judges there is little burning in the cylinder and the fuel is added, resulting in abnormally high fuel
consumption.
b) After confirming the engine mechanical components and oxygen sensors are in normal state, operate the
engine to observe the reading of oxygen sensor, if always greater than 500 mV at normal water
temperature, inspect whether the fuel injector has leakage.
Precautions

Most parts of EFI are non-repairable and generally replaced if confirmed as being damaged.

No mechanism is allowed to operate at engine startup (including the accelerator, i.e., start the engine
without pulling the accelerator).

If engine fault indicator blinks in engine running, it is required to find out the causes and eliminate the
fault as soon as possible.

Leaded gasoline shall not be used, because lead will damage the oxygen sensor and three-way catalytic
converter.

For abnormally rapid fuel consumption, it is necessary to resolve the fault immediately, because some
matter in the fuel will damage the oxygen sensor and three-way catalytic converter.

Valve clearance shall not be too small; if the exhaust port is not tightly closed, the service life of
three-way catalytic converter will be shortened by higher exhaust temperature.
