This sensor is located on the front of the engine. I've had to replace this one before. It's a pain to get to because in order to access the sensor, you have to perform the same steps as you would to change the timing belt. If you look at the front of the engine, just under and to the vehicle's right of the distributor, you should see a wire leading to the sensor. You may or may not see the sensor itself because it's so badly buried. According to the Nissan Service Manual, the sensor, located on the front side of the driver's side cylinder head, detects cylinder head temperature depending on engine coolant temperature. The electric resistance of this sensor decreases in response to temprature rise. If the ECCS detects that this sensor is bad, it will set a Code No. 13 and set the Check Engine Light. My VG30 is in a 1989 hardbody.
it's called VG30 3.0liter V6
It is possible a fuse blew. Check all fuses. If none blown take it to a garage. Check the instrument cluster voltage regulator.
I am not familiar with a vg30 but if it has a carburetor the float fill valve is bad, and if it is fuel injected the fuel pressure regulator, or the injector circuit is malfunctioning.
it manage the amount of fuel going to the system
you need to loosen the motor mount and jack up the engine but first lower the header pie out of the way. iy will give more room
with considerable time, maybe? the only thing they kept the same from the z31 to the z32 was just the VG30 short block the engine was changed to a DOHC engine making it considerably wider, I have owned an 86 turbo and I currently have a '90 N/A. I wouldn't dare try fitting the VG30DE into the z31.
loosen the distributor, have a timing light, preferably an adjustable one, and it should be 15 degrees +/- 2 before tdc. ***See what engine code you have. If it is a Maxima SE (DOHC)(VE30DE engine code) you will have a timing chain instead of belt and probably no distributor. The GXE (SOHC) has the VG30 engine which has the belt...
Cost? 1200 for a rebuild. if your doing a swap go with a VG30 transmission, its much stronger and the adapter can be purchased for ~$100
get under hood and rev your motor manually.......till you hit around 2000 rpms than while keeping motor reved adjust the cap....now if you are too advanced on your cap youll hear a popping missing noise.....back off the cap counter clockwise till the engine runs smooth....if you retard the cap too much the engine will run with a hesitation....that's the closest youll get other wise youll nweed to hook it up to the computer at the Nissan dealer and theyll chargre the hell out of you ***See what engine code you have.

First, is there a chain or belt? Secondly run down to your local parts store and pick up the haynes or chilton repair manual for a few bucks and follow the step by steps given there. good luck. ****See what engine code you have.

Also, I do like the Haynes Manuals better, but both state: "This manual does not contain info specific to the VE30DE engine...MAKE SURE YOU SPECIFY AT THE PARTS STORE, I KEPT GETTING THE WRONG PARTS, EVEN NISSAN ALMOST DID THIS, GOOD THING I LOOKED AT THE COMPUTER...
its possible, some people would go as far to swap in the VG30DETT, due to the fact that an N/A VG30 has higher compression pistons that can detonate when boosted and using lower octance gas. its possible, but not really recomended.
I believe that you have the VG30 engine, if this is true you have to remove all of the belts and to do that you must find all of the adjuster screws for the accessories that are attached to the appropiate belts and lossen the pivot bolts. once all other belts are removed you can begin replacing. my advice is to replace all the belts while you are there and save your self from the hassle of this again.
