Temperature Sender


Recommended Posts

Is there a way of checking the temperature senders? I've tried two different ones, one gives a reading of three quarters on the gauge when hot and the other only goes to quarter.

Assuming its an injection CIH then yes. Think its in the manta and carlton manuals. Might have been off a bosch wiring diagram for the LE system.

I checked mine, was a case of connecting 2 wires to the sender unit linked to a DVM (multimeter) to check the ohms, plonk it into boiling water and the resistance changes, just can't remember the actual readings!!!!

A more simple way could be to take the sender and connect (but dont mount) then take a pot of boiling water and stick it in, measure the temp using a cooking thermometer and see if the temp gauge in the car follow the thermometer down as the water cools.
