If the RPM display on your 2010 Hyundai Accent is not working, there could be a few potential causes for this issue.
Faulty RPM sensor
The RPM display relies on a sensor to measure the rotational speed of the engine. If the sensor is malfunctioning or has failed, it could result in the RPM display not working. This can also lead to difficulties starting the car, particularly in wet weather, as moisture can interfere with the sensor's operation.
Wiring or connection issue:
Another possible cause could be a problem with the wiring or connections related to the RPM sensor or the instrument cluster. Loose or damaged wires or connectors can disrupt the signal transmission and cause the RPM display to stop functioning.
Instrument cluster malfunction:
The issue may lie within the instrument cluster itself. If the display module or its internal components have failed, it can result in the RPM display not working while the engine still runs. This could also affect other functions of the instrument cluster.
The issue of difficulty starting the car in wet weather could be unrelated to the RPM display issue and might be caused by other factors such as moisture affecting the ignition system or spark plugs.
