Eurovan MV V6-2.8L (AXK) (2002)
-
Set multimeter for resistance measurement and check resistance of sensor heating between terminals 3 + 4 at connector for oxygen sensor.
Specification: 2.5 to 10.0 Ohms
If a short circuit is found in the oxygen sensor heater:
-
Replace Heated Oxygen Sensor (HO2S) -G39-.
NOTE: When oxygen sensor is replaced, adaptation values in the Engine Control Module (ECM) must be erased. See: Powertrain
Management/Computers and Control Systems/Engine Control Module/Service and Repair
If oxygen sensor heater has continuity:
Checking voltage supply
-
Set multimeter for voltage measurement and connect it to terminals 3 + 4 at connector to control module.
-
Start engine, and let run at idle.
-
Measure voltage supply and observe display group 41, display field 2.Htng.bef.cat.ON indicated: Specification: 11.0 to 14.5
VHtng.bef.cat.ON/Htng.bef.cat.OFF (alternating) indicated: Specification: oscillating between 0.0 and 12.0 V
-
Switch ignition off.
If there is no voltage:
