| Engine Coolant Temp Sensor Questions |
|
I'm getting a code pointing to my engine coolant temp sensor and from what I've seen I think the LR3 has two, one that communicates with the dash and one that communicates with the ECU. Can anyone confirm this? When I try to find the part number or anything to see about a replacement I can't figure out if it's giving me just one because it's out of stock or because there isn't actually two and also no idea what the part numbers are for each one. I just need to replace the one that communicates to the ECU if there are in fact two of them.
Also, I read something about a calibration or soak period that calibrates the coolant temp sensor and the air intake temp sensor, does anyone know anything about this?

I thought by this age there is only 1 sensor.
The ECU could do a sanity check at cold start. If the air and coolant temps are significantly different, one of them is faulty
maybe this one ?

Whoops guess I should’ve mentioned it’s a 2005. The Workshop manual doesn’t seem to explicitly say that there’s two but it has two different sections that detail how to remove the sensor and each section is nearly identical except the picture of the location is different so I guess that means yes there’s two? Thanks LR for making it so easy lol
