Can we Start a Sticky train on here for ECM OBD I Codes?


I have the codesfrom my GM Service Manual But I'm Missing some and need the Codes from a 3800 Series I Supercharged engine Specificaly the Code 56.


Codes for 3800 Series I (Vin Code L)


Code 13 Oxygen (O2) Sensor Circuit (Open Circuit)


Code 14 Coolant Temperature Sensor (CTS) Circuit (High Temp. Indicated)


Code 15 Coolant Temperature Sensor (CTS) Circuit (Low Temp. Indicated)


Code 16 Battery Voltage Too High or Low


Code17 Spark Referance Circuit


Code 21 Throttle Position Sensor (TPS) Circuit (Signal Voltage High)


Code 22 Throttle Position Sensor (TPS) Circuit (Signal Voltage Low)


Code 23 Intake Air Temerature (IAT) Sensor Circuit (Low Temp. Indicated)


Code 24 Vehicle Speed Sensor (VSS) Circuit


Code 25 Intake Air Temperature (IAT) Sensor Circuit (High Temp. Indicated)


Code 26 Quad-Driver (QDM) Fault


Code 27 Gear Switch Diagnosis (2nd Gear)


Code 28 Gear Switch Diagnosis (3rd Gear)


Code 29 Gear Switch Diagnosis (4th Gear)


Code 31 Park/Neutral (P/N) Switch Circuit


Code 34 Mass Air Flow (MAF) Sensor Circuit (GM/SEC Low)


Code 38 Brake Input Circuit


Code 39 Torque Converter Clutch (TCC) Problem


Code 41 Cam Sensor Circuit


Code 42 Electronic Spark Timing (EST) Circuit (Crank Sensor)


Code 43 Electronic Spark Timing (EST) Circuit (Knock Sensor)


Code 44 Oxygen (O2) Sensor Circuit (Lean Exhaust Indicated)


Code 45 Oxygen (O2) Sensor Circuit (Rich Exhaust Indicated)


Code 51 MEM-CAL Error (Faulty or Incorrect MEM-CAL)


Code 66 Low A/C Refrigerant Charge


Code 69 A/C Head Pressure Switch Circuit








3.1(Vin Code T)Have most of the same codes except.....


Code 32 Exhaust Gas Recirculation (EGR) Circuit (Electrical Diagnosis)


Code 33 Manifold Absolute Pressure (MAP) Sensor Circuit (Signal Voltage High-Low Vacuum)


Code 34 Manifold Absolute Pressure (MAP) Sensor Circuit (Signal Voltage Low-High Vacuum)


Code 35 Idle Air Control (IAC) Circuit


Code 41Cylinder Head Error (Faulty or Incorrect MEM-CAL)


Code 53 System Over Voltage


Code 54 Fuel Pump Circuit (Low Voltage)


Code 61 Degrated Oxygen (O2) Sensor


Code 66 A/C Pressure Sensor Circuit

i have stickied this..great info..thanks!

code 56 for the 92s was a known ecu flaw. it is to be ignored. its a vats code.
