SOURCE: how to reset the service engine soon light

If there is an Auto Zone or any other large auto parts store, have them scan the truck for the DTC codes. The DTC codes will identify the Issues that needs to be addressed in your engine and transmission that has set off the service engine light on. Once the issues has been resolved, the light will reset it self after the third start up and after 40 start up will erase it self from the history as long as there is no additional issues. Good luck and hope this helps, Shift suddenly become very hard. When going from park to either reverse or drive it slams into gear. 1-2 and 2-3 shifts are also harsh. All gears seems to work. Problem may be intermittent: Check TPS for smooth electrical response. If the response is jumpy or erratic at all, replace TPS.

SOURCE: Service engine soon light is flashing

When the light comes on without flashing, it just means an emissions problem, when it starts to flash it has become more serious. I suspect that there was an error putting the plugs and or wires. That computer can determine if there is a misfire and it will put out a P040X, code where X represents which cylinder is the problem. This will help you not have to take each one apart. If there are more than one, check each number.

Ex. P0401 means there is misfire on cylinder number 1

P0400 is a random misfire detected.

If you take it to an Advance or Autozone they will usually scan if for free.

By the way, if you used cheap plugs instead of platinum plugs that could do it too.

Hope this helps.

2004 Ford expedition check engine soon light is flashing and car shakes hard when stepping on the accelerator


Your car is misfiring. You should not drive the vehicle while it is misfiring. If you want to DIY it you can start with you ignition system. Make sure all spark plugs, plug wires, and ignition coils are secure and in good condition.

The check engine light is flashing


Why Is My Check Engine Light Flashing? Location
  1. The check-engine light may be a graphic of an engine or similar icon, or it may contain the words "check engine" or "service engine." In some vehicles, a red check-engine light means the car needs absolute immediate attention while a yellow check-engine light means you need to make an appointment soon. Either way, you should know the location of the light and periodically glance at it to ensure its status. The light is used to indicate power train problems that are associated with your vehicle's emissions system. (The power train is the engine, transmission and other power parts of your vehicle.)
Flashing Light
  1. Typically, a flashing light is more serious than a solid check-engine light. The flashing light is meant to alert you that you may have a misfire in your engine that will cause catalytic converter damage if you leave the problem unresolved. Replacing a catalytic converter can be costly, so have the engine checked as soon as possible by a certified mechanic.
Cause
  1. A flashing check-engine light generally indicates that there is a failure in the emission control system. The emission control system contains an array of sensors that work to reduce the amount of pollution released into the air. An oxygen sensor reads the air and fuel mixture and lights up when it is out of range. The acceptable range is between 50 mill volts and 800 mV. If the check-engine light is flashing, you should visit your mechanic or dealer as soon as possible.
Loose Gas Cap
  1. A gas cap that isn't twisted on tight enough may cause the check engine light to illuminate, but it won't flash. Try tightening the gas cap and watch the light. In many cases, it will turn off because the problem has been corrected. If the light stays on for more than a day or two, have your mechanic run an on-board diagnostic (OBD) to see if there is a code in the system indicating a serious problem. Your mechanic can reset the light to off if the problem was a loose gas cap.
Spark Plug Wires
  1. As spark plug wires age, they can become brittle and crack, causing an electrical misfire. Your check engine light might turn on and stay lit. If this happens, go home as soon as possible, turn off your engine, and inspect the wires. If the wires are brittle and cracked, you need to replace them. If your check engine light stays on after the wires are replaced, have your mechanic run an OBD.

The srvice engine light may not be the check engine light. The srvice light could be an indication to change your oil, or take your vehicle to the dealer for scheduled maintenance. Do you have the owner's manual to check?

2002 Hyundia Elantra Service engine soon light.


When the check engine light flashes, It's not giving out codes. It is telling you that the engine is misfiring on 1 or more cylinders. New plugs and wires might fix your problem.

No passing gear


My car did (past tense) the same thing. The service engine light is flashing until you let off the gas because raw fuel is being dumped into the catalytic converter. The transmission won't shift because the converter is plugged. When you push the pedal to the floor the transmission computer holds the transmission in gear. Meanwhile the engine computer is raising the rpms. It will seem like a transmission problem but it is more likely a plugged catalytic converter. I had converter changed. The engine has A LOT more power, great acceleration and the transmission shifts perfectly.
