My background - 11 years Import only auto tech .
Once purchased - purged entire system of all old data and started fresh with clean / baby fresh ECU knowledge .
To repeat ....
Coolant temp Sensor for ECU is Facet brand from my vendor IMC and in good working order - still getting p0118 and uber rich fuel system.
Single wire temp sensor for gauge changed as well from same vendor and still getting faulty reading at dash and OBDII port live data reading -40 degrees at all times .
Thermostat , coolant , water pump , timing belt , valve check and adjustment ( they were all tight btw ) done - still getting all above mentioned faults .
Its has to be ...
1 - bad wiring from or possibly bad pigtail at coolant temp sensor , from sensor to ECU
2- cluster temp issue = bad cluster
I have not seen a wiring schematic to see if the gauge cluster is in loop to the ECU so that is why I asked about that .
I have seen some Nissan's do that with charging systems .
