Engine codes, how to fix Reply #16 – January 02, 2010, 12:14:40 PM Thanks. The one thing I don't understand is "back probing". Did he strip sone of the rubber coading off the wire? What does this mean? And where is the trottle screw? Quote Selected
Engine codes, how to fix Reply #17 – January 02, 2010, 01:04:55 PM find the factory tps connectorthere you will see the engine harness connector plugged in.if you poke at the area where the wires enter, you will find that its like a rubber gasket/weather proofing material. Thats because that is what it is.shove your meter lead up along any one of the wires and eventually you will be touching some metal where the actual wire is crimped to the terminal.thats back probing,, not the other back probing:evilgrin:-===============actuate the trottle cable or linkage in the engine bay.observe what makes it stop.find the screw that the linkage leans against when its stopped.adjust that screw. (although i would not advise touching the adjustment at all until you finsh your work on the tps). Quote Selected

Anyone know where that plug on our cars is, and heres its suposed to go? I don't even know where to start looking. Quote Selected
Engine codes, how to fix Reply #21 – January 02, 2010, 05:36:36 PM For the code 67, make sure the a/c-heater function control switch is in the off position. Can't see where that rolling idle stuff applies to our cars. Besides you don't have a clutch switch. Quote Selected

It is a current control device.A variable resister used as a potentiometer has wires to both ends of the fixed resister and to the wiper. This is a voltage divider. Quote Selected

Besides you don't have a clutch switch.On an automatic trans it is call neutral drive switch. Doesn't matter this applies to automatic equipped cars as well. I've seen it first hand. R&R the NSS clear code no more rolling idle. The car had no other codes as well...http://sbftech.com/index.php/topic,3137.0.htmlQuote....code 67 does affect idle control, while cruising, coming to stop, while shifting, etc....the system is not able to ID "tranny in neutral" condition...it's assuming system is in gear all the time (reason it does not allow a KOER to be run), and selects the wrong idle strategy.

Engine codes, how to fix Reply #25 – January 02, 2010, 11:23:32 PM Prereq for running KOEO:"Place transmission in park or neutral.Set parking brake.Place A/C or heater control to off."Code 67:Neutral drive switch is open, or A/C was on during self test.If the neutral drive switch is not working, you can't start the car.

Engine codes, how to fix Reply #27 – January 03, 2010, 02:26:05 AM You can get a code 67 with incorrect voltage.AOD NSS for starter control, pin 30 gets its ground reading (to id in-neutral state) through the starter solenoid coil and the ground from the solenoid body to the fender apr0n..... the starter doesn't work in any gear position but P or N..... the problem could be in the wiring from the ignition switch to pin 30. In park or neutral it SHOULD see 12 vdc at the pin.The signal MAY be shorted to ign. on.....Here's how it's been explainedQuote1. Pin 30 connected to starter solenoid coil through NSS, isolated from SIGRTN.2. When starter is not engaged and tranny in N or P, pin 30 signal is grounded through the coil @ the starter solenoid "S" connector, as shown in the starter solenoid diagram below. The solenoid takes the place of the SIGRTN reference ground in a manual tranny setup.3. NSS switch open (Any position other than N or P) = In Gear4. NSS Closed (P or N) = In Neutral (Pin 30 signal grounded through starter solenoid)5. When the ignition switch is in "Start", 12-vdc are routed back to pin 30.6. Pin 30 circuit is protected internally by an in-line diode, making the presence of 12-vdc during start-up to the ECM, a no problem/harm condition. The wire to the pin may have an open condition.....Would explain the code AND the startup ability....IIRC, this all ties in to the dreaded ignition switch as well....Let's go back to this......QuoteI'm not too concerned with 67, I know I can shift the car out of gear without the key being inserted into the ignition.Can you take the car out of park without a key? More importantly -- without a key and with the ignition in the OFF position? Quote Selected
