Error Code 2111 - No RPM Signal - Diagnostic Help Requested - Now Needing More Help!!!

[robert_a_dupree at bankone.com]

Well we did the diagnostic on the error code last night.  For those of you
interested here's the proceedure.

1.  Unplug the engine speed sensor (grey color)

2.  Measure the resistance between pins 1 & 2.  You should see 1000ohms.

3.  If target resistance is found then measure between 1&3, and 2&3.  These
      should be open circuits (infinite resistance).

4.  If that all checks out and you still have the code, then replace the
      sensor.  If it doesn't check out you have a wiring break somewhere.



Well we did that.  We replaced the sensor.  Can is running like total sh*t.
      Barely run at idle.  Code is still there.

Had to adjust the mixture a bit to richen it up, and had him drive the car
      at over 3,000rpm for better than 5 minutes.

Code is still there.



I am beginning to wonder if the problem is in the ECU?

Can we check feed voltage (+5v?) if the ignition is in the on position?

What pin is feed voltage, which is ground?

What pins on the ECU correspond?



HELP HELP HELP!
