First of all, does the Titan have a Throttle Position Sensor (I'm thinking all EFI cars do) and if so, what is the voltage spread as it relates to throttle position? Most are 0 - 5 Volts (0 being idle, 5 being full throttle). JetTech, anyone???

There are two TP sensors.. The voltage ranges from .36V (ign. on, engine not running, closed throttle) to 4.75V (ign. on, engine not running, full open throttle.)

Outstanding! Do both TP Sensors read the same range? Just out of curiosity, which wire/TP Sensor did you test? Your wide open throttle reading I would imagine will increase slightly with the engine running but of course you can't test it with the engine running unless you have little regard for your engine's health. Thank you scr38! Your a gentleman and a scholar!

Both sensors are the same range. I did not measure the voltages, they came from the service manual. I have a OBDII setup, and get all my readings from it. It gives the TP in degrees of opening.

I gotcha. 0 - 5 Volts is typical for most TPS's. Sounds like the Titan is no exception. Thanks again!

why do you want to know this? does it have something to do with NOS? :wink: :wink:

NOS? Now why would you think that. :wink: Yes, I am piecing my Nitrous setup together and I want to use a TPS switch for activation but most of them only read the typical spread of 0 - 5 volts. Sounds like any of them will do the trick.

yea i figured that was what it was for, good luck with that. make sure you read the artical that the head just did about melting down his NOS solinoid :( mabye try a different brand of NOS

I just read his thread actually. I have never personally had any problems with NOS solenoids but I have heard from friends and just talking with people in the pits that they are junk. Who knows? One thing about solenoids of any brand, they don't like heat and it's kind of hard to avoid heat under a hood. I will try and mount mine as far away from any direct heat sources as I can. Haven't decided exactly where yet though. In the past I have purchased nitrous KITS just to find the hoses are the wrong length and I have alot of parts left over that I never need. This time, I will piece a system together with all the right stuff. Here's a little teaser pic. This was the bottle and bracket that was going in my 1996 Z28 before I sold it. The Titan's setup will be similar . . .

The components I have been using are used so I'm sure that was a contributing factor to the failure.

Make sure you have another switch on your system since full throttle out of the hole won't be at the recommended 2500-3000 rpm minimum activation rpm for nitrous.

Hmmm . . . I never really had a problem before but then again, this will be the first Automatic trans vehicle I have run Nitrous on and my launch will likely be below 2500RPM's as the OEM Torque Converter is pretty tight. With a stick you are over 3K on the launch usually so maybe I will have to look into an RPM window switch for safety. I wonder why they don't recommend activation below 2500RPMS. If the throttle blade is open full, why not? Probably to hard on parts that low in the RPM band. Hmmmm . . . Thanks again Head!
