KA24DE Temp. Sensor

[CoL]

I noticed that my temperature reading was jumping around from -15 to 80 in my consult display. I disconnected the red temp sensor on the manifold and the temp reading stoped jumping and stayed at 80 (where it should be).

Does anyone know which temp sensor Nistune is taking its reading from? I thought it was the red one that is on the manifold with the red connector. When i disconnected it, Nistune was still getting a temperature reading.

thanks.

80 is the reading you'd get if it was unplugged.

When I boot bench my ECU the temp sensor reading slowly climbs to 80 even though there is no temp sensor.
Makes sense for the engine ecu to act that way in case of temp sensor reading failure failure, the care will just be hard to start cold but should run normally when car is warm.

Thanks for the info! Thats exacly what my car is doin. I'm off to see the thieves at Nissan for a new sensor.
