Sorry to resurrect a dead thread here, but I am having a hard time diagnosing my issue with a code 67.It's actually the NGS. Nuetral Gear start circuit.
It's wired in parallel between the clutch pedal switch, and the sensor on top of the t-5. Only one has to be closed to tell the ECU you are in neutral, which will affect idle strategy.
To bypass it, just take the plug off the clutch switch, and stick a 5A blade fuse in there. This tells the ECU you are always in neutral and prevents some idle issues such as hanging idle. as well as the ability to run codes.
BTW, if you are doing this only to allow you to continue reading codes, just run the test with the clutch pedal pressed in the entire time.
You'll want to either connect up the NGS on the T-5 or, bypass it with the fuse to prevent hanging idle issues. What's the reason it's not connected on the t5? AOD-to-T5 swap?
Here you are saying that EITHER transmission has to be in neutral, OR clutch pushed in.
However, I am getting a code 67 even with clutch pressed, and my A/C is deleted.
I even tried sticking a fuse in the clutch switch to bypass, and it still gave me code 67?
What could be the possible causes of this?
