If car is not over heating i would not wory about it, but if you are woryed about it this is what you can do. open hood and take off the neg. battery cable and leve off for about a minute or two. this will erase any codes that are stored in the computer. after you waited the minute or two reconect the cable and start the car it may stall a couple of times but should run allright after that, the computer has to reset all the sensors. just drive car if light comes on take it and have it scaned then you know if you got a proplem or not. good luck.

Wont start after driving..


first see if its got a check engine light if it does that could be the answer to the problem. next if you mean you put the car in gear and rev the engine and it goes nowhere than the trans is either bad or the shift sensor is. i doubt its the coolant temp sensor a good test would be to just let the car idle for a half hour and see if the radiator fans come on. but like i said check the engine light first.

My feul pump works and the engine start but after ruining for 10.min the engine goes off,i don't know the courses of the issue maybe fuel pump failure or sensor .i need help


Sounds like a sensor, maybe a CPS sensor, with engine cold the computer runs off of a preset setting (called closed loop) but when the engine reaches operating temp the computer switches over to an open loop , where it will then take readings from various sensors, the usual culprit is the Crank Shaft Position sensor (TPS) , you can remove it and have it tested, Autozone or Advanced Auto Parts should be able to do this. If the engine light comes on you can hook up a code reader to retrieve any past stored codes and go from there...

Buick park avenue engine start problem


Try replacing the coolant control temp sensor, the one to the computer (usually it will have two wires), not the sensor to the temp light or gauge (usually has only one wire).

Hard starting when cold ( engine cranks normally )


see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

Check engine light comes on when setting interior temp to warm when placed back to cool light goes off after few hours. check engine light code low coolent level temp


a. check thermostat and temperature sending unit b. check coolant level! (this should be a.!)
start the engine ,let it warm up a little, take off radiator cap, should see coolant circulating in radiator- if it isn't after a reasonable amount of time, then your thermostat may be defective! if it is flowing, your temp. sensor may be bad- or, perhaps, a loose wiring connection.
these newer cars can make it difficult to actually see what's happening with the coolant, so no guarantees!
good luck!

Coolant sensor may be the problem. It is located near the thermostat housing. It may be sticking between modes & not operating properly.Also make sure coolant is circulating in system.

My 1987 Chevrolet Z24 Cavalier cooling fan will


since you have already tested fan and relay and both work, the problem may be the engine temp sensor. There are two sensors. One goes to instument cluster. This is engine coolant temp sensor, the other is engine temp sensor which is usually attached to engine block, sometimes they are connected to thermostat housing with the coolant sensor. You can pully the engine temp sensor and test that sensor same way as relay. (with mulitimeter)

Does the Check Engine light come ON when this happens? Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Otherwise, guesswork. I have MANY ideas that could send you on a wild goose chase. I strongly suspect EMS (Engine Management System) sensor beginning to malfunction as it warms up. First strong suspicion is the crank position sensor (CKP) - however,usually always sets a DTC (i.e., P0335, P0336). The next suspicion is the Engine Coolant Temperature sensor. The ECM uses this sensor's signal to adjust fuel, timing, engine RPM, etc based on engine temp. If malfunctioning at a particuar point during engine warm up, it could be telling the ECM the temperature is LOWER or HIGHER than it ACTUALLY is, resulting in the ECM to increase fuel (flood it) or give it LESS fuel (starve it). If this malfunction lasts long enough, the ECM will usually set a DTC for that sensor circuit, either a Range/Performance code, or a "LOW Input" or "HIGH Input" code.
