To reset the engine malfunction light on a Renault Clio 1.4 16v, you can use an OBD-II scanner to clear the fault codes stored in the vehicle's ECU. Simply connect the scanner to the OBD-II port, read the codes, and then select the option to clear or reset them. Alternatively, you can disconnect the car battery for about 15 minutes to reset the ECU, but this may also reset other settings. Always ensure that the underlying issue causing the malfunction light is resolved before resetting.

ecu?
The spelling "malfunction" is correct.
Yes, the Malfunction Indicator Light (MIL) may remain illuminated on a Toyota even after replacing the sensors if the new sensors have not successfully transmitted data to the Engine Control Unit (ECU). This could indicate that there is still a communication issue or that the ECU is not receiving the correct signals. It’s important to check for any additional fault codes and ensure that the sensors are properly connected and functioning. A diagnostic scan may be necessary to resolve the issue.
ecu?
yes the ecm and the ecu is the same thing. ecu stands for electronic control module and ecu stands for electronic control unit. they are both the same thing just ecm in canada and ecu in america.
