The temp sensor problems you're having might be due to wrong resistance values or a bad sensor.(It's new doesn't mean it's good) Jetronic systems have several different temp sensors(the rear one) that uses the same plug but have different temperature-to-resistance curves. Definetely check if you have the right one first (Fastest way to check is to consult the repair manual and test both temp sensor resistance values while the engine's cold and after fully warmed up) The gauge cluster uses the single wire sensor(the front one), which is more likely to give out false readings when there's a ground fault. Check your engine grounds and cluster wiring, add grounds when needed. Also, the ECM does not take any readings from the gauge except RPM info, so any fault in the cluster should not affect engine performance(and that's why there's two temp sensors, one for the ECM one for the cluster, to make sure they don't interfere with each other) Wish you can figure out the situation soon

Its like Honda that has 3 temperature sensors, one in the thermostat housing for the fans, one single wire for the cluster and one under the dizzy for the ECU

@@bleeedthebrakes and its like a different sensor, cuz if was a short to ground like the insulation got cut or something like that the gauge will be pegged to "H" also another test would be to disconnet the sensor and see of the gauge move, that works on older Nissan and Datsun
