Jetta V6-2.8L (BDF) (2002)
-
Check Oxygen Sensor (O2S) wiring of Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) -G130-.
See:
If the Oxygen Sensor control in display zone 1 does not fluctuate in the stated range:
-
Press the -> button.
-
Press buttons -0- and -6- for function "End output" and confirm entry with the -Q- button.
-
Carry out a road test to remove possible residue on Oxygen Sensor (O2S) and repeat check.
Observe the valid safety precautions when carrying out a road test. Refer to "Fuel Delivery and Air Induction/Service Precautions".
See: Fuel Delivery and Air Induction/Service Precautions/Technician Safety Information
If the specifications in display zone 1 are not obtained even after a road test, or the value does not fluctuate:
-
Check Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) -G130- for aging.
See:
Possible causes of Diagnostic Trouble Code (DTC) if sensor regulation frequency is too slow:
-
The slots or holes in sensor body are blocked
-
The sensor breather hole in area of connecting cable is blocked
-
The sensor has been overheated (glazed)
-
The sensor has been damaged by leaded fuel
Check basic voltage of Oxygen Sensor (O2S) Behind Three Way Catalytic Converter (TWC) -G130-
-
Remove protective cover -arrows-and disconnect 4-pin connector (black) -1- to Oxygen Sensor (O2S) Behind Three Way Catalytic Converter
(TWC) -G130-.
-
Connect multimeter to measure voltage at terminals 3 and 4 (connector to Motronic control module) using adapter cables from VAG 1594.
-
Start engine and measure basic voltage.
Specification: 0.400 to 0.500 V
-
Switch off ignition.
If the specification is obtained
-
Replace Oxygen Sensor (O2S) 2, Bank 1 after Three Way Catalytic Converter (TWC) (G130), item 18.
-
Check DTC memory, repair malfunctions if necessary and then erase DTC memory.Refer to "Displaying and Reading Trouble Codes/With
Manufacturer Scan Tool/DTC Memory Checking and Erasing".
See: Computers and Control Systems/Testing and Inspection
-
Erase learned values and adapt Motronic Engine Control Module (ECM) -J220- again.
-
Read readiness code. If the DTC memory has been erased or the Motronic Engine Control Module (ECM) -J220- was disconnected from battery
positive (B+), the readiness code must be generated again. Refer to "Monitors, Trips and/or Drive Cycle (Readiness Codes)/Reading Readiness
Code".
