I'm reading a code 41, TPS short...The number 4 injector sounds like it may be shorting (pinging louder than normal, like an electrical short). Could this cause a code 41? If so, is there a writeup on changing out injectors somewhere? If that's the case I mean and it's not the plug/harness.

PS did a search and came up with alot closely related but nothing exact so far. Thanks in advance guys for a link.

 

41 is the Throttle Position Sensor signal... not that there's a short in the TPS signal. Anyways, even if there was a short in the TPS signal it is not likely ONE injector is gonna muff up the TPS since all injectors are wired and fire at the same time.
When in doubt- follow the codes........

Hmmm K, Got this From here: http://en.allexperts.com/q/Toyota-Re...runner-3-1.htm

Guess he's not such an expert.

Guess I'll change out the TPS and adjust first as I have another. Thanks for the thoughts!

 

before you go too far, realize that an open could be a total loss of signal or a value much higher than expected, and a short could be a value much lower than the ECU expected.
It won't always be the absolute open or short.

I gave you a link to help you test it, and you don't seem to care, so do what you're going to do.

 

Know that link well...Said...THANKS! LOL

I just want to get this done in the shortest amount of time possible and was hoping for a miracle answer. For the most part these trucks are a joy to work on. Except when it comes to engine stuff/ Damned thing needs to be replaced with a 350.
