Correct setting for ECU Temp Sensor

Hi all,

I recently got my 22rte back on the road and the setup is running on a Link Atom II with the G4+ Software.

I have a stock 84-88 Toyota Ecu Coolant Temp sensor like the one pictured (m12x1.5)

It isn't reading correctly, I tries the Bosch NTP and the Cal 1 table. Anyone know what setting to use for a 80's Era Toyota Sensor? Sensor is new but still the square plug Toyota variant.

If no setting exist, what Sensor is recommended that has the same thread pattern?

Thanks!

Nearly all denso sensors use the standard bosch curve so that is odd for it not to work for you - it is possibly a Chinese clone which tend to be a bit like a game of Russian Roulette.

If you can you measure the resistance at 20deg (or whatever your common room temp is), the resistance at 0deg (in a cup of ice water) and the resistance at 100deg (in a kettle of boiling water). Then report those 3 resistances and I can generate a cal for you.

Thank you for the reply. I did a manual calibration last night at many different temps and recorded resistance values. I went ahead and input everything in my Cal 1 table (setup for F and Ohm) and was still getting temperatures that didn't match values I knew to be true.

It must be as you suspect a cheap Chinese variant and possibly even a faulty sensor, or my measurement were inaccurate. A new Bosch NTC 0280130026 is only 15 bucks so I think I will pick one up to make life easier.

Thank you all for the help! It's much appreciated.
