Hey guys I have a 1995 Accord V6. I have two codes:

P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Input
P0141 Secondary Heated Oxygen Sensor (Secondary HO2S) (Sensor 2) Heater Circuit Malfunction


What do those mean, and how can I fix them? Also, can these be related to the car not starting sometimes. I sit there and crank and nothing. I already replaced the main relay, but that did not help. Any ideas?

 

both are sensors that just need replaced, 02 and Coolant temp sensors

 

Could that be why the car sometimes doesn't start? I forgot to mention that I just bought the car about 2 weeks ago. I got the car with the light on already, but it was running. Now it sometimes doesn't want to start.

I've changed the main relay and the fuel filter.
