51-7 error code

I have changed the throttle position sensor and unit still throws this code. If you go thru the glow plug warm up process, it comes on instantly. However, if you don't go thru the process and just start the unit, it will not throw the code until the glow plug timer clicks off. Doesn't make any sense. Any ideas?
