DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION

Condition
The switch of the sensor between rich/lean and lean/rich is checked continuously by the engine control module (ECM). The switch times are measured according to how high or low the electrical consumption is. This check is carried out at fuel shut-off and at re-engagement after fuel shut-off. Diagnostic trouble code (DTC) ECM-D00E is stored if the engine control module (ECM) registers a fault.
- engine coolant temperature (ECT) above 50�C (engine at operating temperature)

- speed above 30 km/h
- engine speed (RPM) higher than 1000 rpm.
