    ECU codes correction

    "6 - Crank Angle" is incorrect. 6 is ECT: engine coolant temperature. 4 is Crankshaft Position sensor (CKP).

    here is a correct list:

    Honda 4-Cylinder ECU Troublecodes:

    0: ECU
    check the ECU electrical connector. if no loose connectors are found, have the ECU diagnosed by a dealer service department or other qualified repair shop.

    1: Oxygen Sensor "A" (Primary)
    defective circuit or unplugged / defective sensor

    2: Oxygen Sensor "B"
    defective circuit or unplugged / defective sensor

    3: MAP Sensor (Manifold Absolute Pressure)
    defective circuit or unplugged / defective sensor

    4: CKP Sensor (Crankshaft Position Sensor)
    defective circuit or unplugged / defective sensor

    5: MAP Sensor (Manifold Absolute Pressure)
    mechanical problem / disconnected piping

    6: ECT Sensor (Engine Coolant Temperature)
    defective circuit or unplugged / defective sensor

    7: TPS (Throttle Position Sensor)
    defective circuit or unplugged / defective sensor

    8: TDC Sensor (Top Dead Center)
    defective circuit or unplugged / defective sensor

    9: CYP Sensor (Cylinder #1 Position)
    defective circuit or unplugged / defective sensor

    10: IAT Sensor (Intake Air Temperature)
    defective circuit or unplugged / defective sensor

    12: EGR Lift Sensor (Exhaust Gas Recirculation)
    check the hoses, the EGR valve lift sensor and the System EGR valve.

    13: BARO Sensor (Atmospheric Pressure)
    defective circuit or unplugged / defective sensor

    14: IAC Valve (Idle Air Control)
    defective circuit or unplugged / defective sensor

    15: Ignition Output Signal
    missing or defective ignition output signal

    16: Fuel Injector System
    defective circuit or unplugged / defective fuel injector

    17: VSS (Vehicle Speed Sensor)
    defective circuit or unplugged / defective sensor

    19: Automatic Transmission Lock Up Control Solenoid Valve
    defective circuit or unplugged / defective solenoid valve

    20: Electrical Load Detector
    defective circuit or unplugged / defective sensor

    21: VTEC Solenoid Valve
    defective circuit or unplugged / defective solenoid valve

    22: VTEC Oil Pressure Switch
    defective circuit or unplugged / defective oil pressure switch

    23: KS (Knock Sensor)
    defective circuit or unplugged / defective sensor

    30: Automatic Transmission Signal: "A" / SEAF / SEFA / TMA or TMB
    defective circuit or unplugged / defective sensor

    31: Automatic Transmission Signal "B"
    defective circuit or unplugged / defective sensor

    41: Primary Oxygen Sensor - Heater
    check the heater for the proper voltage signal.

    43: Fuel Supply System
    check the fuel pressure, fuel pressure regulator. check the oxygen sensor. also, check for vacuum leaks.

    45: System Too Lean or Too Rich
    malfunction in the fuel monitoring systems

    48: LAF Sensor (Lean Air Fuel)
    defective circuit or unplugged / defective sensor

    54: CKF Sensor (Crankshaft Speed Fluctuation)
    defective circuit or unplugged / defective sensor

    58: TDC Sensor 2 (Top Dead Center)
    defective circuit or unplugged / defective sensor

    61: Oxygen Sensor, Heated - Sensor 1 (Primary)
    high voltage, low voltage, or slow response

    63: Oxygen Sensor, Heated - Sensor 2 (Secondary)
    high voltage, low voltage, or slow response

    65: Oxygen Sensor Heater (Secondary)
    malfunctioning or defective oxygen sensor heater

    67: Catalyst system Efficiency Below Threshold
    malfunctioning or defective catalyst system

    70: Automatic Transmission
    malfunction with the automatic transmission controls

    71: Cylinder 1 Misfire or a Random Misfire

    74: Cylinder 4 Misfire or a Random Misfire
    a condition is present that is creating a cylinder misfire

    7:5 Cylinder 5 Misfire or a Random Misfire
    a condition is present that is creating a cylinder misfire

    76: Cylinder 6 Misfire or a Random Misfire
    a condition is present that is creating a cylinder misfire

    80: Exhaust Gas Recirculation
    insufficient flow detected

    86: ECT Sensor (Engine Coolant Temperature)
    circuit range / performance problem

    90: Evaporative Emission Control System
    leak detected in the fuel tank area

    91: Fuel Tank Pressure Sensor
    low input

    92: Evaporative Emission Control System
    insufficient purge flow

    when do you get the codes? i know that you watch the ecu under the passenger foot area, but is it when you start the car? my car is running on 3 cylinders and has an idle problem, and im pretty sure ill get a code, but i dont know how to get it
