496HO TPS low range?
Hi guys!
I just did a pre-startup test on my engines for the weekends startup.
I just put the ignition on and tested to see if they ware able to crank. They did crank but after 0,5 sec I got an an alarm from my Smartcraft system saying TPS low range on stb engine.
I know this is the throttle position sensor, but is it dangerous to start her up in the weekend anyway? I just tested to crank her for 0,5 sec to see before I take her out of the garage. Could this error code be just that I didnt fully crank her?
I will check for loose connections and corrosion but I doubt it.
Please give me some feedback about this, it dosent seem to be that common..

What is a TPI/TPS High or Low Range fault?
The TPI/TPS sensor diagnostic fault calibration within the ECM, can alert the technician of a fault condition where the sensor is above or below the normal operating range. This fault is not the same as an open or short circuit fault. Possible causes may be loose or
misadjusted throttle linkage and excessive wear on components connected to the TPI/TPS.

Thanks, Ill test this weekend!
Everything was working fine when I took her out of the water in Oktober so I dont think there is any misadjusted throttle linkage..
Is there a manual online for the smartcraft system? Can i check the engine with it the same way as Rinda scan tool? Cant find any reset error code...

Hi again, I need help!
Ive tested to move the TPS sensor from stb to port and the other way around, smartcraft still complains on low range TPS on stb side? That would rule out a bad sensor I guess?
And now I also get engine fault critical on both starboard and port engine?
Is there a way to get more info out of the smartcraft or do I need to hook up a scantool?

Should i be able to measure that with a regular fluke? I live far off where the scanners are hard to find but Ill see if I can locate one.
BUT, after todays fail search, the engine fail alarm goes off when I turn the ignition on, and comes back when turn ignition off ( no problem just as it should be then)
The strange thing with the TPS sensor is that i I give the throttle for the port engine 1/2 gas then alarm stops?!
Port side works fine, if I move the sensor from port side to strb and vice verse the error stays the same, no matter of which sensor I use. I need to have the throttle at 1/2 on strb for the alarm to stop?
The throttle axles have the same position.
Conclusion: Sensor is ok.
Now what?

The difficulty would be checking its operation while the cap is on. There's no easy access to the connections for using a fluke. You may be able to identify the correct pins on the computer connector however. They are easier to get to with a meter even when connected.
The cap and wire connections to the TPS may very well be the problem. They are fragile. My friend had a rough time tracking down a bad connnection to his seawater presure sensor cap on his 496.
