Sometimes the manufacturers code the vehicle's computer to come on to remind owners it is due for servicing. Disconnect the negative battery cable for about 15 minutes. This should reset the computer and cause it to initiate a diagnostic cycle. If the light comes back on, check the fuses. My car blew a 40 amp fuse each time I hit the brakes too hard, causing the light to come on. Although it is not recommended, I changed it to a 50 amp fuse and the light never came on again.

My heating just stopped working as I was driving what can be wrong with it


Check your coolant level after the engine has cooled and check radiator reservoir also . Its best to check with the engine cold because it more of a precise level then with the engine at operating temp. Plus you take a chance a getting burned really bad checking the antifreeze with the engine at operating temp also. On the side of the reservoir is a max fill line somewhere about half way down and with the engine cold,that's where the antifreeze level should be when its full. The reason the max line isn't at the top is because of expansion when the engine temp rises. Good luck and stay safe and keep us posted!

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.

1986 nissan pickup z24i. will run when spray start fluid but wont stay running. just installed the engine


Did you hook all the lines for the fuel pump up when the engine was re-installed? It is definitely a fuel issue. Disconnect the fuel line and crank over the engine to check for fuel supply.

Hold light blinking, check engine light on, engine slows down


check tps sensor (throttle position sensor in backside of the throttle cable) and map sensor (manifold absolute pressure on front little 1 inch sensor with vacuum line) make sure there plugged in. the ecm (engine control module driver side inner fender) and tcm (transmission control module under dash) both need the data to know when to upshift and increase fuel/air. Otherwise the computer runs default values and guesses off of other sensors giving poor performance. also disconnect battery for 15 min. usually resets aveo service lights if you dont have a scanner.

Temp line comes on and stays on


If it's flashing, it can mean it's overheating. STOP DRIVING. First Check the electrical connector, if it's plugged in, it should be ok. Next, pull the return line off the overflow and start the engine (with the engine cold) and the return line should almost immediately start flowing water, if not, your water pump is broken and not pumping and overheating your engine.

There is no radiator cap, the "overflow" is the radiator cap.

Engine running at 1500 rpm to 3000 rmp when started but stays at 1500 at a red light when driving car stay at 2000 to 2500 rpm


Your problem is typical to a vacuum leak. Check all of the vacuum lines connected to the engine for proper connection, and make sure there are no cracked vacuum lines. If you don't see any vacuum hose problems you will need to check the intake for leaks. The easiest way to do this is to take a spray bottle full of water and spray it around the intake and intake hoses with the engine running. If there is a change in engine RPM's while spraying with water, inspect area for the source of the leak.
