Exhaust gas controlExhaust gas control systemOn-vehicle inspection1. Check oxygen sensor.(a) Let the engine run at idle speed for 3 minutes to ensure oxygen sensor reaches operating tempera-
ture of 350(b) Place digital universal meter at DC voltage gear, and connect 2 terminals respectively to (gray) pin
and (black) pin of sensor, and voltage should fluctuate
quickly between 0.1-0.9V at the moment.
Warning:Perform inspection immediately after warming
up vehicle.If voltage change could not be confirmed,
it is necessary to heat oxygen sensor again.Exhaust gas control - Exhaust gas control system2. Check rotating speed after fuel cut off.(a) Accelerate engine at least to 3500rpm.
(b) Check the operating noise of injection nozzle with listening device.
(c) When throttle is released, check the operating noise of injection nozzle recovers after stop.3. Check fuel evaporation exhaust control system.(a) Check the pipe clamps of connecting pipeline between
charcoal canister and carbon canister solenoid valve are
firmly clipped and check there is leakage.
(b) Check there is trouble with fuel evaporation exhaust con-
trol system with failure diagnostic instrument.4. Visually check hose, joint and hot fin.Check cracks, leakage and damage.
Hint: the disconnecting of engine oil level gauge, oil opening
cover and PCV hose may cause running failure of engine.
The cracks, looseness and not connecting at the intake
system between throttle and cylinder head will result in
redundant air entering and running failure of engine.23

5. Check heater resistance of heated oxygen sensor.(a) Uncouple oxygen sensor joint.
(b) Place digital universal meter at ohm gear, and connect 2 terminals respectively to 1# (white) pin and
2# (black) pin, and the resistance under normal temperature is 166. Check fuel tank cover.Visually check fuel tank cover and gasket are distorted or damaged.Exhaust gas control - Exhaust gas control system 24 Oxygen sensor
