So the check engine light came on, and I got a P0126 Code Coolant Temp Insufficient. I changed the coolant temp sensor, and still have the light on. What else should I be looking for?

Coolant temp insufficient is likely a bad thermostat. Lots of people seem to run I think it is 180 deg. Thermostat, do dome reading...... and make sure you get the system bleed out correctly.

had a mechanic shop scan and said he came up with low coolant sensor in expansion tank, i scanned it came up w/ po126 thermostat or ECT sensor, where is the ECT temp sensor on a 2011 range rover sport super charged SALSH2E48BA704784 ????, please let me know idk where to find pictorial coolant diagram for this thing, I'm imagining there could be two sensors correct?
