If your Honda Engine displays 'batt' indicating an under charged battery, the suggested solution is to replace or recharge the battery.
What to do if my Honda Engine has insufficient oil?
If your Honda Engine has insufficient oil, it could be due to a low oil level. In this case, add the recommended oil to the proper level. Alternatively, it could be due to an abnormal issue, requiring you to replace the oil level switch, or replace or repair the engine wire harness and/or control wire harness.
Why does my Honda Engine show E-02 (Abnormal battery voltage)?
The E-02 error code on your Honda Engine indicates an abnormal battery voltage. This could be due to an issue with the battery itself, in which case you should replace or recharge the battery. It could also be due to a faulty ignition switch, so replace the ignition switch. Another potential cause is a problem with the engine wire harness or control wire harness, requiring you to replace or repair them.
What to do if Honda Engine displays E-01 (Starter motor switch input failure)?
If your Honda Engine displays error code E-01, indicating a starter motor switch input failure, the fuse may be blown, so replace the fuse. Alternatively, the ignition switch may be faulty, requiring replacement. Other potential causes include issues with the engine wire harness, control wire harness, remote control box, or remote control harness, all of which may need replacement or repair.
How to fix E-00 (Starter motor failure) in Honda Engine?
To fix the E-00 error (starter motor failure) in your Honda Engine, start by checking the battery; replace or recharge it if necessary. If the issue persists, adjust the ignition pulse generator air gap. If that doesn't work, consider replacing the ignition pulse generator, the wire harness, the starter motor, or the flywheel. It may also be necessary to replace or repair the engine wire harness and/or control wire harness.
What causes E-04 (Governor function failure) on Honda Engine?
The E-04 error on your Honda Engine indicates a governor function failure. This could be due to a faulty throttle control motor, requiring replacement. Alternatively, there might be an issue with the engine wire harness or control wire harness, necessitating replacement or repair. In some cases, the inverter unit may also be the cause and need replacement.
How to address E-03 (Engine temperature sensor failure) in Honda Engine?
To address the E-03 error (engine temperature sensor failure) in your Honda Engine, you should replace the engine temperature sensor. Additionally, inspect the engine wire harness and control wire harness for any damage, and replace or repair them as needed.
What to do for E-05, E-06 errors (GCU internal failure or inverter unit internal failure) in Honda Engine?
If your Honda Engine shows errors E-05 or E-06, indicating a GCU or inverter unit internal failure, you might need to replace the stator. Also, check the main wire harness and control wire harness for any issues and replace or repair them as necessary. The inverter unit itself may also be the problem, so consider replacing it.
What does it mean if Honda Engine displays E-12, E-13, E-22, E-23 (Inverter protection activated)?
If your Honda Engine displays error codes E-12, E-13, E-22, or E-23, it indicates that the inverter protection has been activated. Disconnect the AC appliance and stop the engine. Then, restart the engine and check the error code. It may also be necessary to replace the stator, main wire harness, generator wire harness or the inverter unit.
How to troubleshoot E-11, E-21 (Inverter internal communication error) on Honda Engine?
To troubleshoot E-11 or E-21 errors (inverter internal communication error) on your Honda Engine, consider replacing the stator. Also, inspect the generator wire harness and replace or repair it if necessary. If the problem persists, the inverter unit may need to be replaced.
