Electronic anti-theft device:
Pay attention not to cut off ECM normal power supply circuit while installing anti-theft
device.
Charcoal canister:
The charcoal canister is controlled by the ECM to adjust the fuel steam volume that goes
into the engine through the charcoal canister so that the fuel will not affect the normal
operation of the engine. The fuel tank evaporation and exhaust control effect is directly
subject to the volume of the charcoal canister. If the canister is too small, the fuel steam
may leak in the case of long-term idle speed or substantial fuel steam production.
Two. Basic checking
Wire harness terminals are reliably fixed;
Fuel circuit and vacuum pipeline are reliably fastened;
Air hose of canister solenoid valve is correctly positioned and securely fastened;
Screw tight the bolts on the oxygen sensor and three-way catalyst and ensure sealing of
fittings; check the exhaust system with 1.3 times atmospheric pressure if necessary to see
if there is any apparent leakage.
Three. System initialization setup
