Won't Shift!!!!!!

J1290,'

You are not OBD II. That's why the recepticle won't work. Not familiar with OBD II plugs. Go back to autozone & tell them it's OBD I, or Try using a paper clip & grounding the pins as indicated in the scans.
 
To pull any DTC codes.

Connector looks like below.

|01|02|03|04|05|06|07|08|
|09|10|11|12|13|14|15|16|

Take a piece of wire and short PIN 4 TO PIN 12.

Turn the ignition to run (don't start the engine).

Look at the Dash Cluster LCD.

The modules and any codes for the modules will be displayed.

Module 1 CCM (Central Control Module)
Module 4 PCM/ECM (Engine Computer)
Module 9 ABS (Anti lock brakes)
Module A DERM (Air bag)

Post the code and someone can look up what it means.
 
I believe C12 indicates the CCM is functioning correctly.

H22 Throttle position Sensor. Low voltage signal.

H64 Throttle position Signal Malfunction. The EBTCM is not receiving reference voltage from the Rhrottle Position Sensor.

H67 Throttle Position Sensor Comparision Malfunction. A throttle position circuit fault is detected by the PCM, which sends an error signal to the EBTCM.

I hope I am reading this correctly. Never been involved with kinda stuff before, thank God. Getting it out the manual, just hope I am interpeting the info correctly.

Appears that your problem is related to Throttle Position Sensor?
 
Rabbit is correct.

ok heres the codes people module first then code


1 c12
4 h22
9 h64
9 h67

C12 just indicates the diags. are running

Module 4 ECM/PCM H22 indicates a Throttle Position Sensor
problem.

The TP sensor provides a voltage signal that changes relative to the throttle blade position. Signal voltage should vary from about .6 volts DC at idle to about 5 volts at Wide Open Throttle.

DTC 22 sets when the TP sensor voltage is less than .23 volts DC.

Action taken: The Malfunction Indicator Light will illuminate, transmission TCC (Torque Converter Clutch) will apply high transmission line pressure, harsh shifts, fixed shift points and no fourth gear in hot mode.

Check the connector on the TPS which is mounted on the passenger side of the throttle body shaft. Verify the screws are tight and the electrical plug is making good contact.
If everything looks good I'd replace the sensor.

The electical connector has three wires.
Black is ground
Dark Blue is the sensor output
Gray wire is the 5 volt reference from the ECM

If you have a volt meter, with a sewing pin pierce the wire insulation. With the ignition in run (engine off) measure from the Dark Blue wire and the Black wire. You should measure about .6 volts DC. As you manually move the throttle the volts should smoothly increase to around 5 volts.

ABS DTC (Diagnostic Trouble Code) 64 and 67 are Throttle Position signal malfunction.
 
This is a picture of one on a Camaro. Yours should look the same. The sensor is held on by two torx screws. There is no adjustment.

On the throttle body is a lever that moves. The movement is transfered to the Throttle position sensor as the throttle body blades open and close.

located it and it looks like its been off by the look of the bolts that holds it in, but all the conections look good, is there a way to test it?
 
the problem was that there was a tps enhancer on the car, i took it off and the problem went away. these vettes are crazy to work on and trouble shoot
