I have a 88na with a 87tII motor and when i put the code reader on it its giving me a code for bad pressure sensor. I replaced the pressure sensor with another that was guarenteed to be tested and working and its still giving me the same code. it has a 318 sensor, is this the proper sensor for the 87 tII motor.

I have had a thread going about Boost Sensors recently and I asked about the N318. from what jdm12a says, it is for a JSpec A/T ECU. I think what you need is the N332. What ECU do you have? Is your car a MT or AT?

I have an 87 T2 that is mostly stock and I have the N318 boost sensor. Check and make sure the wiring is all connected and intact. I had a problem with the ground wire pushing out of the connector, thus making my boost guage spike. Possibly your signal or power wire has done this.

my 88 tII has the N318 boost sensor too

Well, I could be wrong :-P I am waiting on my N370 and FCD for my S5 T2 to get here that I ordered from woundup7 in Seattle. It was just a related topic that was discussed in my post about the boost sensors I had going there for a little bit. I am not running the S4 so I dont know that much about them other than there are subtle differences between the two to make a difference. But, you came to the right place asking about boost senors thats for sure https://www.nopistons.com/forums/pub...IR#>/bigok.gif

Ill be sure to go over the wires again. thanks alot for the suggestions
