Perform visual inspection for each checking point as follows.

a. Check corrosion inside of Lambda sensor terminal.

b. Check damaged coverring and open in component wiring.

c. Check connecting torque(poor connection) of Lambda sensor component

d. Disconnect Lambda sensor and check deformation, clogging, melting of Lambda detecting prove.

Specification : Everyting OK

Is any problem of Lambda sensor detected?

YES

Replace Lambda sensor and go to "Verification of Vehicle Repair".

Refer to "NOTE" as follows.

note

In diesel engine, ultra lean combustion generates at normal operating condition. Therefore, Lambda sensor signal change in accordance with engine acceleration and various loading condition rarely happens, unlikely to linear Lambda sensor of gasoline engine. Moreover, pumping current is not measurable with normal measuring device(ampere meter) because maximum value is 3mA. If DTC code is recorded continuously eventhough circuit inspection is correctly performed and no problem at visual inspection of component is detected, replace Lambda sensor.
