those codes were low voltage or some bs. plugged in or not, should not set the light. my egr, rear o2 and purge solenoid are 100% gone, plugs just sit there doing nothing.

The reason it's not connected is because this is a 1998 PCM swap into an older car. The 98+ evap system is different than the older stuff and incompatible so when I rewired the PCM connectors I left all the evap wires out.Originally Posted by Swiggles
I can give those pins 12v through current limiting resistors to simulate the solenoids being present and trick the computer.
...but I should be able to turn off these codes with software and I'd like to solve it that way if I can.

I'll stick with the 98 bin file then. I have three PCM's total for this car and they are all the same part # and are from 1998 vehicles.
I guess I'll get to work on copying everything over to that newer osid bin file and see what happens.

plug the new one in and flash away.

I copied everything over to the newest osid bin file this morning and programmed the existing PCM with it.
When I first started the engine I actually got more of the P16xx improper voltage codes for other pins that's I didn't connect, but after going back and and setting them to 3 and doing a partial write, they all went away. This osid seems to actually respond to the changes I make so I think the problem is solved.

sounds good. if you have a hand held code scanner, check for "im readyness" evap should be ready with out any drive cycles.

Oddly I remember someone having trouble with EGR codes/emissions not going green. hahahaha

it was evap......only thing i need to wait to be "ready" is the o2 sensor.
