06-07 engine wire harness diagram

Anyone have the pin out for the throttle body from tb to ecu ? I need to ohm out the harness I'm getting a code for it and have already replaced the plug and 10in of the wiring. Installed another tb.

What’s the code ??…you normally don’t “ohm out” issues like this…resistance checks tell you NOTHING !!

Yes, only if the wire is broken…if chaffed almost all the way through you will still see good resistance…that chaffed wire (power or the ground)has to handle the current flow…loaded circuit testing with a headlight bulb is how to do it correctly.

Using a labscope to check the P2135 is preferred vs a DVOM to see changes in the TPS 1 and 2 signals…wiring and code description below…is this an OEM TB ??…if not this may your problem !!
