Having changed the thermostat all seems to be much better and generally the car runs at the 12 o'clock position (90 degrees) but I took a trip the other day 35km's to get fish and chips and it sat under and yet on the trip home it was at normal all the way, hence me wondering about sensors and which one controls the gauge. the manual says to run the motor up to temp and stick a thermometer on the. i got solid readings on all the sensors except the coolant temp sensor. Coolant/Water Temp Sensor for ECM (Engine Control Module) Genuine Toyota. i finally broke down and bought a multimeter and started running sensor checks per the Haynes specs. The other is the coolant temp sensor for the temp gauge. Note there are two sensors right next to each other the one I have highlighted is the engine coolant temp sensor (ECTS). I have never had it happen, but I have read here on the board that several people have had problems getting their system to fill properly. G83 has 2 wires and is accessible without removing the filter, despite what the manual says, whereas G62 is a different kettle of fish. 22RE coolant temp sensor check so i've been trying to chase down this problem of running rich. It is easier to get at if you remove the PCV hoisery and some other hoses in that area. Re-set the computer and see if you are still getting the sensor code, if so, it would have to be in the wiring, or like I said before, it could be a bubble in your coolant system. Hi Wino - The plumbing looks quite different as can be seen here with number 2 being the G62 temperature sender on the passenger side and the radiator coolant sensor being G83 which sits behind the the diesel filter on the drivers side. One's described in the CFDs as engine coolant temp sensor, the other one as radiator outlet temp sensor, not sure if the etka pages make sense w.r.t.

Edit: can't guarantee that isn't the same one shown in two different pages, if you see what I mean. This wire comes right off the - terminal of the battery, and follows the + wire leading to the starter.

Both shown as 2-pin on current flow diags.īoth the 06A part apparently.
