#2941, "My list of 95 ECU CEL Codes" Jan-19-07 04:24 PM by TJBrown
I have looked around and didn't see a list anywhere so i thought i would make mine available. Like i said, it is for the 95 ECU.
You get the codes from the CEL by doing the Key Dance. Cycle the ignition key On-Off-On-Off-On within 5 seconds. You will count the number of flashs by the CEL. Numbers are devided by longer pauses and there will be two numbers per code.
11 Intermittent Loss of CMP or CKP 11 No Crank Reference Signal at PCM 11 Timing Belt Skipped 1 Tooth or More 13 No Change in Map From Start to Run 14 MAP Sensor Voltage Too High 14 MAP Sensor Voltage Too Low 15 No Vehicle Speed Sensor Signal 16 Knock Sensor #1 Circuit 17 Closed Loop Temperature Not Reached 17 Engine is Cold Too Long 21 Downstream HO2S Heater Failure 21 Downstream HO2S Shorted to Voltage 21 Downstream HO2S Stays at Center 21 Upstream HO2S Heater Failure 21 Upstream HO2S Shorted to Voltage 21 Upstream HO2S Stays at Center 21 Upstream H2OS Response 22 Engine Coolant Temp Sensor Voltage Too High 22 Engine Coolant Temp Sensor Voltage Too Low 23 Intake Air Temperature Sensor Voltage Low 23 Intake Air Temperature Sensor Voltage High 24 Throttle Position does not Agree With MAP 24 Throttle Position Sensor Voltage High 24 Throttle Position Sensor Voltage Low 25 Idle Air Control Motor Circuits 25 Target Idle Not Reached 27 Injector #1 Control Circuit 27 Injector #2 Control Circuit 27 Injector #3 Control Circuit 27 Injector #4 Control Circuit 31 EVAP Solenoid Circuit 31 Evaporative Purge Flow Monitor Failure 32 EGR Solenoid Circuit 32 EGR System Failure 33 A/C Clutch Relay Circuit 35 High Speed Fan Control Relay Circuit 35 Low Speed Fan Control Relay Circuit 36 Pulsed Secondary Air Injection Solenoid 36 Too Little Or too Much Secondary Air 37 Park/Neutral Position Switch Failure 41 Generator Field Not Switching Properly 42 Fuel Pump Relay Control Circuit 42 MFI Relay (ASD Relay) Control Circuit 42 No MFI Relay (ASD Relay) Output Voltage at PCM 43 Multiple Cylinder Misfire 43 #1 Cylinder Misfire 43 #2 Cylinder Misfire 43 #3 Cylinder Misfire 43 #4 Cylinder Misfire 43 Ignition Coil #1 Primary Circuit 43 Ignition Coil #2 Primary Circuit 44 Battery Temperature Sensor Volts Out of Limit 46 Charging System Voltage Too High 47 Charging System Voltage Too Low 51 Fuel System Lean 52 Fuel System Rich 53 Internal Controller Failure 53 PCM Failure, SPI Communications 54 No Cam Sync Signal at PCM 62 PCM Failure, SRI Mileage Not Stored 63 PCM Failure, EEPROM Write Denied 64 Catalytic Converter Efficiency Failure 65 Power Steering Pressure Switch Failure 66 No CCD Messages From TCM
