    Bin Files for $0D 16197427 PCM. Right click save target as.

    These are known good, not superceeded by GM to a newer chip for issues. There are more and I will add whatever passes as known good to start with.

    16197427 Malfunction Error Codes

    These are general error codes for GM in 1995. All may not apply to 16197427 PCM

    11 Malfunction indicator lamp circuit voltage was wrong for 26 seconds.
    13 Oxygen sensor voltage stays between 0.35 and 0.55 volts for 60 seconds. Engine was at normal operating temperature and had been running for at least 2 minutes after start with a throttle angle above 5%.
    14 Coolant temperature sensor signal indicates a temperature of over 284 F.
    15 Coolant temperature sensor signal indicates a temperature colder than -40 F.
    16 A low resolution pulse was not detected by ECM within 720 high resolution timing pulses.
    18 Injector driver circuit voltage to PCM was wrong for 4 seconds.
    21 TPS voltage was above 2.5 volts for 3 seconds when the engine was running, or when the TPS was above 4.8 volts at any time.
    22 TPS voltage was under 0.23 volts when the engine was running.
    23 Inlet air temperature sensor signal showed an air temperature below -31 F for 60 seconds after the engine has been running for 4 minutes.
    24 Vehicle speed was 0 MPH when engine speed was between 900 and 3000 RPM and throttle position angle was less than 2% for 5 seconds.

    62 Engine oil temperature sensor indicated an oil temperature above 284 F after engine had been running for 30 minutes.
    63 Right oxygen sensor was open showing a steady voltage between 0.35 and 0.55 volts for 60 seconds after the engine had been running for at least 2 minutes with a throttle angle above 5%.
    64 Right oxygen sensor voltage was below 0.2 volts for 50 seconds of closed loop operation.
    65 Right oxygen sensor voltage was above 0.7 volts for 50 seconds of closed loop operation when the throttle angle was above 4%.

    70 A/C clutch relay circuit showed incorrect potential voltage at PCM for 26 seconds.
    72 Transmission output speed changed more than 1000 RPM for 2 seconds when vehicle was in gear, or transmission output speed changed more than 2048 RPM when vehicle was in park or neutral.
    73 Pressure control solenoid return amperage was more than 0.16 amp different than the commanded amperage for 1 second.
    74 Traction control system active signal input was 0 volts for more than 2 seconds when vehicle was in park or neutral.
    75 Ignition voltage was less than set value for 4 seconds when engine speed was above 1000 RPM.
    77 Cooling fan relay #1 control potential voltage at PCM was incorrect for 26 seconds.
    78 Cooling fan relay #2 and #3 control potential voltage at PCM was incorrect for 26 seconds.
    79 Transmission fluid temperature signal indicated a temperature higher than 295 F for 30 minutes, or higher than 306 F at any time.
    81 Transmission 2-3 shift solenoid voltage stayed high for 2 seconds after commanded ON by PCM, or the voltage stayed at zero for 2 seconds after commanded OFF by PCM.
    82 Transmission 1-2 shift solenoid voltage stayed high for 2 seconds after commanded ON by PCM, or the voltage stayed at zero for 2 seconds after commanded OFF by PCM.
    83 TCC PWM solenoid voltage stayed high for 2 seconds after commanded ON by PCM, or the voltage stayed at zero for 2 seconds after commanded OFF by PCM.
    84 Transmission 3-2 shift solenoid voltage stayed high for 5 seconds after commanded ON by PCM, or the voltage stayed at zero for 5 seconds after commanded OFF by PCM.
    85 TCC solenoid remained ON for 4 seconds after commanded OFF by PCM 90 TCC solenoid voltage stayed high for 2 seconds after commanded ON by PCM, or the voltage stayed at zero for 2 seconds after commanded OFF by PCM.
    91 One to Four up-shift lamp control signal showed incorrect potential voltage at PCM for 26 seconds.
    97 VSS output signal showed incorrect potential voltage at PCM for 26 seconds.
    98 Tach output signal showed incorrect potential voltage at PCM for 26 seconds.

    Tuning VE tables with BLM History $OD 16197427

    Dave W from Old School EFI has made a spreadsheet to help get fueling correct when tuning an engine. You enter your current VE table, your recorded BLM from BLM historygram setup in TunerPro Definitions above and it gives you the new VE table for your bin.

    http://www.gearhead-efi.com/Fuel-Inj...r-Spread-Sheet

    Works for a variety of different masks. $42, $E6, $0E, $0D, $31

    Dual vs single knock sensors:

    V8 apps use single sensor. 4.3 V6 uses dual sensors wired in parallel. Code 43 will set if voltage on KS line is incorrect. Dual sensors can be used on V8 or single on V6 by changing max voltage parameter to set code 43.

    Single Sensor
    ; ERROR 43
    ; KNOCK SYSTEM FAIL
    ;---------------------
    L4E6A: FCB $A0 160 ; 16 SEC'S. HI VOLTS CK PERIOD
    L4E6B FCB $E6 230 ; 4.5 VDC A/D UPPER VOLTS LMT
    L4E6C FCB $14 20 ; 0.390 VDC A/D LOWER VOLT LMT

    Dual sensors:

    L4E6A: FCB $A0 160 ; 16 SEC'S. HI VOLTS CK PERIOD
    L4E6B FCB $A2 162 ; 3.17 VDC A/D UPPER VOLTS LMT
