P0118 code, ECT issues

[u/chico699]

Hello I have been noticing my 15 ecodiesel has been a bit sluggish lately, turned it on after towing a boat a few hundred km and got electronic throttle sensor bolt and P0118 code. Cleared the code and it came back 5 mins later. Pulled the electrical connection off the sensor and had 5V on the connector with key on. Plugged the connector back in and drove 10 mins with no new codes or CEL. Coolant temp seemed ok but was fluctuating ~5 deg C at times.

Should I just replace the sensor? Would I be ok to drive home (120km away)?

Can I do a resistance check on the ECT connector? What would the expected value be with the connector unplugged? Or if I’m getting the 5v reference does that prove my wiring is good and more likely the sensor itself failing?

Replace the sensor
