| FAQ - Answer 1 | When your 'Service Engine Soon' light illuminates, that is an indication that there is a potential issue with the drivability, electronics, or emissions of your engine. |
| FAQ - Answer 2 | Preventative maintenance should be referenced in your owner's manual, and, while repairing or having your 'Service Engine Soon' light repaired, if your vehicle is due for maintenance, yes. As described in your owner's manual, this maintenance will help prevent future issues. |
| FAQ - Answer 3 | Possibly. Sometimes, the triggering device will reset itself thus turning off the 'Service Engine Soon' light until that device/sensor is tested by the vehicles on board computer again. If it fails the test again when tested, the 'Service Engine Soon' light will illuminate once again. Some devices/sensors when tested and failed will illuminate the 'Service Engine Soon' and it will not go out until correct service work is performed. |
| FAQ - Answer 4 | General Motors has designed the vehicle to inform its driver if there is an issue with certain devices/sensors that effect the drivability/emissions. If this is ignored, there is a possibility that the drivability will suffer, fuel economy will be decreased, or the emissions being emitted will be increased. Do not ignore the 'Service Engine Soon' light. |
| FAQ - Answer 5 | No. When state and local officials perform certified emission tests, one of the first steps in the process is to inspect for a 'Service Engine Soon'. If it is on, it will automatically fail the test. |
| FAQ - Answer 6 | No. The 'Service Engine Soon' is related to engine emissions and drivability conditions. Please refer to your owner's manual maintenance schedule for information pertaining to tune up time intervals. |
| FAQ - Question 1 | Is there a problem when my 'Service Engine Soon' light appears? |
| FAQ - Question 2 | While investigating what triggered the 'Service Engine Soon' light, do you recommend any additional services? |
| FAQ - Question 3 | If I don't investigate the problem, will the light turn off by itself? |
| FAQ - Question 4 | If I ignore the light, will there be consequences? |
| FAQ - Question 5 | Is it possible for my vehicle to pass an emissions test if the 'Service Engine Soon' light is on? |
| FAQ - Question 6 | Does the 'Service Engine Soon' light tell me when my vehicle needs a tune-up? |

Frequently Asked Questions for Generic Horn (High Note)
How do I ensure Generic Horn (High Note) fits my specific vehicle?
Verify your vehicle’s exact Year, Make, Model, Engine Size, and Trim Level using our vehicle selector above. Since manufacturing variations occur mid-model year, matching your original equipment (OE) part number or verifying fitment against your 17-digit Vehicle Identification Number (VIN) is the most accurate way to guarantee compatibility with E1903E.

This component complies with Federal EPA emissions regulations for 49-state legal use.
