2009 sensor problem

Hi there! I have a 2009 Accent with about 108,000km and a few months ago the Transmission Input Speed Sensor went on it according to our OBD. Ordered one in and replaced it and immediately after resetting the Coolant Temp Sensor went. Ordered and replaced but the code won’t go away and now car won’t start. Does anyone have any suggestions without taking it to a shop if it all possible?

OBD II doesn't really say that a sensor is bad.
It just suggest to start your troubleshooting in that area.
You could have bad wiring or a faulty sensor
Just replacing parts isn't always the correct route to fixing the CEL

Check the voltages and grounds going to the sensors
Believe the powers are coming from the ECU?
Maybe one of the sensors or wires are shorted??

Would there be anything that you know of to cause the wiring to go like that? It’s all strange that after replacing one sensor the other popped up and it’s all very odd to us.
