DTC ECM-D00E

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) ECMD00E is stored if the engine control module (ECM) registers a fault.

- engine speed (RPM) higher than 1000 rpm.
