Where is the temp sensor on a 93 northstar?
Which temp? Oil, Water or Outside air?
93 Mazda MX3 computer says its water temp sensor or circuit how do you know which wire is broken you have replaced the sensor twice already?
You may want to use a paper clip or small section of wire to jump over the contacts on the plug of the temp sensor. Harness side. This is done with the wire unplugged from the temp sensor. The wire that leads into the plug may be broken. If this dosent work cut the plug off and twist the wire togather. If the warning stops you found the problem.
If a 93 is the same as a 94 you will find the temperature switch above and slightly to the right of the oil filter (round plug). The temp sensor is located further right and slightly down from the temp switch (about an inch but hard to see). The temp sender for the dash guage is located above and to the left of the oil filter. Good Luck, Tom J.
temp sensor on the 99 miata is on the back of the cylinder head in a housing. it's easy to see and get at with the coilpack removed. also wanted to correct an earlier answer on 90-93 miata temp switch, which is in basically the same place. the switch on the top of the thermostat housing front of engine is for the cooling fan.
