SOURCE: Check engine light

The trouble code P1128 is for a faulty mass air flow sensor or MAP. This is a common problem with 1999-2000 Accents. There is air leakage within the unit and/or the hot wire in the unit is badly contaminated. A bad MAP will cause the vehicle to bog and loose power.

This is an Evaporative Emissions System code - indicates the computer has checked the system and concludes there is a leak in the system (small leak).. could simply be a loose fuel cap.

How can I reset check engine light?


You need an OBD scanner. The link below shows what one looks like:
obd Google Search

However, the check engine light is / was on for a reason. You should first use an OBD to identify what the error code - the fault - is and rectify it.

Once a fault is rectified the oBD scanner will be able to reset the check engine light.

It's probably easier and cheaper to get a mobile mechanic to do it for you.

How do I clear check engine light


The check engine light is set by the onboard computer detecting a malfunction or out of tolerance condition. The code(s) can be read with an OBD-II scanner. Once the condition(s) that cause the codes are repaired, the code can be cleared with the OBD-II scantool. You can purchase these tools at local auto parts stores. Be careful though; the cheapest ones will only read the codes, but cannot reset the Check Engine Light.

2003 S60 reset check engine light? /faulty gas cap seal, repaired


If you disconnected the negative cable battery (soft reset) and the fault code come back again, you will need using an OBD scanner reader in order to know if other fault code stay there.

Hope this helps.

The check engine light is on my 1995 Saab 900s. I can not find a techician with the correct scanner.How can I turn off the light?


There are three ways to reset a check engine light.

1. Disconnect the battery, wait approximately 30 minutes, reconnect the battery. This resets the cars computer which also reset the check engine light. On newer OBD (on-board diagnostic) compliant vehicles this usually does not work. See step 2.

2. Reset using an OBD II reader. When you hook an OBD II code reader up to your vehicle, you can reset the computer using the code reader.

3. Fixing the problem. Generally the check engine light comes on for a reason. Usually it is emission related (sensors, gas cap) or electrical (faulty wiring). In this case the way to reset the check engine light is to fix the problem

2000 beetle- while driving yellow emissions symbol came on. what does that mean?


This is OBD - On - Board -Diagnostic Display.
On Board Diagnostics, OBD-II, is required on all automobiles and light trucks from 1996 onward. OBD-II is a set of specifications for monitoring and reporting on engine performance in modern automobiles.
If the Service Engine light is on, then connecting a Code Scanner on OBD Connector, the Code is picked up and the code explanation can be found. If this is a False Code, this can be Cleared with the code scanner, after reading the code. The location of OBD-II connector in your car can be found here:
http://www.obdclearinghouse.com/index.php?body=oemdb
Remember the Check Engine light only comes on for emissions-related failure (which includes fuel and ignition, too). A separate warning light will illuminate if there are non-emission problems such as low oil pressure, charging system problems, etc.
If the light is on because of a misfire or fuel delivery problem, and if the problem does not occur after three drive cycles, the Check Engine light may go out. Whether the light goes out or remains on, a code will be snt and remain in the computer memory to help you diagnose the fault.
More information for the codes can be found here:
http://www.aa1car.com/library/ic10224.htm
After the code is picked up with a scanner, the code explanation is founded, and a decision has to be made to fix the problem or to clear the code. This can be done with the same scanner. If you do not have a scanner, any AutoZone, or Advance car parts store can do it for free.
