Where is the Z31 cylinder head temp sender?

[Guest lombrozo]

Trying to help father-in-law with 1984 300ZX non-turbo. Error code says cylinder head temperature sensor is bad. I can't find it anywhere. Three different places shown in the manual. It is supposed to be a two wire connector.

Anybody have a clue? Sure appreciate it.

Thanks

David

About 3/4ths of the way down.

you have to remove the fan shroud and then look at the front of the engine to the right (looking at front) of the thermostat housing buried back in there you should see a unit with two wires. same connector as a fuel injector. the wires run up and over to the passenger side of the engine. there is a write up on how to change do google search. basically you bust off the plastic end of the sensor (after removing the connector) and then you can get a socket on there and remove the unit. It isn't very tight (or shoudln't be). then you need a wobble socket or an overlarge socket to get the new one in. If you have a new FI connector you might want to change that they are usually fried by now. Follow the wires all the way up to the top of the engine and make sure the large plastic oval connector up there is good. Doesn't need to be brutally tight. all it does when you tighten the new is bring the nose of the sensor in contact with the metal of the engine too tight you might crush the sensor. hope that helps.

if i were to describe it, I'd say

 

behind the timing cover, to the right of the thermostat housing, almost directly underneath the distributor.

Make sure you replace the CHTS sub harness when you change the CHTS. (CHTS = Cylinder Head Temperature Sensor)

I actually need to do this to my Z31 as well. I've purchases a new CHTS, I just haven't messed with installing it yet.

That's also on Xenon's site, just not in pdf.
