OK, the best action now would be to scan the ecu for any trouble codes that may be stored at this point with a diagnostic computer. this action will describe the issue concerning the check engine light and, it will also direct you to the location of the failed sensor that may be damaged at this time.

In most cases, this light will illuminate if a vital sensor has failed to register a signal for a short time or, if the sensor circuit is open.

I recently replaced the engine on my Citroen c4 2005 model, now the warning lights stay on, the engine overheat, abs and anti pollution warning lights stay on.


The problem for engine overheating rise due to insufficient refrigerant. Try recharging the refrigerant tank with fresh refrigerant and water. If the refrigerant in the tank is of poor quality then also engine overheat.

The reason for ABS light to come may be due to air in the brake fluid line. Try brake bleeding to remove the air bubbles. Also the faulty brake actuator line may cause the problem. Check for actuators on each wheel.

Pollution warning light comes on if the exhaust system not works properly. Check for faulty Oxygen sensor or faulty catalytic convertor.

My abs light and check engine light comes on some times when i start it, and stays on till i turn it off, but sometimes they dont dont come on at all?


You should have the computer scanned for trouble codes. When the check engine light or ABS warning light is on the computer should record trouble codes to direct the mechanic as to what to check.

Need to find location of the check engine light


When you turn the key switch on, all of the warning lights including the check engine light should come on and stay on until the engine starts.
If your model has the bar of warning lights below the speedo and tach it should be in there.

Left the keys in the ignition adn had AAA jump it. Now the T/C with a slash through it came on and the light that says low engine power. The car starts really rough and has no power when u drive it. WHats...


T/C light = Traction Control

Could be something going on with a wheel speed sensor. You'll have to have the ABS/TCS controller scanned for any stored trouble codes to see why the controller is turning on the light. The code(s) might help you to determine what part of the system is faulting. You'll have to take it to a shop that has a high end scan tool.

If the TC light is on, chances are there is a trouble code set and stored in the computer. You need to determine what the code is. If you take the car to a nationally recognized parts store, most will scan the computer for free, so there is no money out of pocket for you.


Actron also makes a ABS code checker called BrakeScan. Don't know how good it is, but it might be good for a DIY person.

TC Explanation:

If your vehicle is equipped with the Enhanced Traction System (ETS), this warning light should come on briefly as you start the engine. If the warning light does not come on, then have it fixed so it will be ready to warn you if there is a problem.
If the warning light stays on, or comes on when you are driving, there may be a problem with your Enhanced Traction System and your vehicle may need service. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly.
The Enhanced Traction System warning light may come on for the following reasons:
If you turn the system off by moving the shift lever to FIRST (1), the warning light will come on and stay on. To turn the system back on, move the shift lever back to a position other than FIRST (1). The warning light should go off. The warning light will come on when you set your parking brake with the engine running, and it will stay on if your parking brake does not release fully. If the transaxle shift lever is in any position other than FIRST (1) and the warning light stays on after your parking brake is fully released, it means there is a problem with the system. If the traction control system is affected by an engine-related problem, the system will turn off and the warning light will come on. If the Enhanced Traction System warning light comes on and stays on for an extended period of time when the transaxle shift lever is in any position other than FIRST (1), your vehicle needs service.

1997 camry all warning lights on for a while


Just tell them of the smell. They will start by checking all fluids to see if any are low. And do a visual inspection to look for stains or whatever the smell was from. Do you know what a bad catalytic converter smells like? It is described as sulfurous, like rotten eggs smell. This part is in the exhaust piping, and used to clean pollutants from the exhaust.
Now about those warning lights in your dash: those red lights are supposed to always come on when the key is turned to on and then to start. They turn on with key on, and then soon as engine starts (or right after-within a couple of seconds) the warning lights should all turn off. So I'm not sure if you just hadn't noticed them before, or what. Do they seem to stay on for an extended period of time? The only reason a red light would stay on after engine starts, would be a warning that something not right. (Like if the "dripping oil" light would stay on, that is a danger, cause that is your engine oil pressure. If that light stays on, you lost oil pressure, and meaning shut engine off immediately before damage occurs.)
So the warning lights come on as a visual check that those bulbs are good, just in case a warning is needed. Then engine starts and all warning lights should go off. See? Good luck, probably not a big problem, but good you check it out.
