The check engine light is triggered by the Engine Control Module (ECM). The ECM receives information from many sensors and determines when to illuminate the check engine light.
The check engine light on a 2003 Honda Accord will be triggered when something on the engine is malfunctioning. To rid the check engine a light the ECU will need to be reset.
Any tampering with an O2 sensor will cause a check engine light. So, you can not bypass.
Check Engine Light is triggered by a fault with the emissions system. You have a problem with the emissions system. Code is stored in ECU and can be accessed with an OBD2 scan tool. Maintenance Required Light is triggered by mileage and just means service is required, normally oil change.
Reset with an OBD2 scan tool, after the repair of whatever triggered the light.
No - the check engine light is strictly a communication device. Does not perform any functional role beyond that.
Try disconnecting the battery for 5 minutes. If that does not work you will need an OBD2 scanner to reset it. Of course if you do not fix the problem that triggered the check engine light it will just come back on.
The "Service" light is just a maintenance reminder that is triggered on mileage. The "Check Engine" light is triggered by emissions system problems. Typically the O2 sensors trigger the check engine light but also a fuel cap that is not tightened, or a misfiring cylinder.
The check engine light is triggered by the vehicle's computer when a fault is sensed. Have your computer scanned for the trouble codes. An OBDII scanner will be necessary, there are some auto parts stores that will scan free of charge.
Once this lamp is triggered by a fault, you will need to have a diagnostic tool to plug into the diagnostics plug to clear the fault.
it means a sensor has triggered your control panel and you need to check your engine. You can have a diagnostic reading and it may be something simple like a damaged sensor or a pcv valve or you can relish the mystery like most until it breaks down.
Check with the Clerk's Office of that court, or notify police or sheriff's office. Tampering with evidence is a crime.
