Check engine light/fuel temp sensor

My check engine light came on so I took it in to have it checked. They tell me my fuel temperature sensor is bad. Cant find out where it is on my van & no matter where I research it I find it keeps telling me I dont have one. Could they be talking about another sensor?

My girlfriend is having the same problem with her Mitsubishi Galant. The code should go away after they scan it, but before they scan it try tightening your gas cap a few more turns. It seemed to work for her, it might also be your oxygen sensor(O2 sensor). It should be located on your exhaust manifold(headers). Hope this helps.

What does faulty temp sensor has to do with starting of the car?


When a temp sensor goes bad, it usually fails to a setting that makes the ECM think the coolant temperature is about -40 degrees F. This makes the ECM send MASSIVE amounts of fuel to the injector(s) in what it thinks is an extremely cold start. This causes the engine to flood and makes for a hard start. You may be able to get the car started if you do a "Clear Flood" procedure, which is to hold the gas pedal to the floor while cranking until the car starts. Even then, though, the car will run so rich that you may have to keep revving the engine to keep it from stalling out at idle. On the road, it may seem better, but your fuel mileage will be awful.

Temp sensor


I'm not a 100% but it sounds like your camshaft position sensor went bad then caused the other codes to come up because the camshaft position sensor tells the computer how much gas it needs. So it started a chain reaction with the fuel level sensor, fuel temperature sensor, and knock sensor codes. The Fuel temp. sensor helps the engine to know how much fuel to inject as well depending on the temp. of the fuel. The fuel pressure sensor senses the amount of fuel in the fuel rail by reading the internal pressure of the rail, so that's what leads me to believe that it's your camshaft position sensor. Particularly if that was the first code that came up. Hope this helps you.

Hi

The engine temperature sensor is bad. If so, the ECU assumes the engine is warm and it leans out the mixture, but you need a richer mix when cold, so it will run lousy till it actually gets warm.Check your coolant temp sensor. It may be defective and telling the computer that the engine is already warm. The computer is supposed to add extra fuel when cold to "choke" the engine until it reaches operating temp. If the sensor is reading incorrectly the computer may think its warm and not add the extra fuel to keep it running smoothly. Also check the two ground wires connected right next to the thermostat housing for loose or corroded connections. A bad ground here can also lead to running problems. If the sensors test ok have the timing checked.

Pull your diagnostic codes. The codes will tell if the sensor is not right.

Please get back to us if you have further query or else please accept this "particular" solution.

97 altima got spark, fuel, compression but won't start


If it won't start while cold, it could be the cold start fuel injector is not working or clogged. Check also for a large vacuum leak which could be diluting the fuel mixture. Check for a bad MAP or MAF sensor.

If it won't start hot, look for leaking fuel injectors or an engine coolant temperature sensor disconnected, the wires to it broken, or a faulty sensor. If the engine coolant temp sensor is stuck at full cold (which it would be if disconnected), it will tell the computer the wrong engine temp and the computer will schedule too much fuel for a hot start leading to flooding.

When it reaches operating temp it dies and wont restart for almost 45 min


This could be a lot of things, but the first thing I would check is the water temperature sensor that tells the fuel injection system how hot the water in the engine is. If the fuel injection thinks the car is cold, it supplies extra fuel and eventually the engine floods. This should set a check engine light and code, although the code in this situation will usually point to some other component that does not agree with the water temperature sensor rather than to the actual culprit.

2005 chrysler sebring malfunction light is on engine stall when cold


Could be a bad battery connection. Your fuel system may be going bad. Might have a faulty coolant temperature or intake air temp sensor. Could even be a MAP sensor. Is your check engine light on?

Temp.gauge not working and the fan runs constant with poor fuel economy.


The most likely cause is due to the radiator fan constantly running and the engine not getting to operating temperature, thats why your temp gauge isnt going up, check all related wiring to the cooling fan and make sure there no bare wires that could be causing a short to ground causing the fan to constantly run, secondly check the fan relay, if all of that checks out check the coolant temperature sensor because the information from that sensor tells the computer when to turn the fan on and off, if the sensor is bad it could be telling the computer the engine is hot when in fact its not.

My check engine light is on, and today my temperature gauge stopped working and we have replaced the engine coolant sensor and the connector and temperature gauge still not working. PLEASE HELP


Could be the thermostat. I know nothing about cars but I noticed my 2000 Grand Prix temp gauge was not going to the normal level. My wife drives this car so I didn't notice it for a month or so. Eventually the Engine light came on. Took it to Autozone and the code came back as P0180... (1) low coolant (2) bad thermostat (3) enginge fuel temp sensor. They used a code reader that was about the size of an Ipod nano.

Coolant was okay, so took it to my mechanic. His netbook sized computer showed it was the Thermostat. He reset the codes and the temp guage went back to normal. Was short on $40 for the fix at the time, so I parked the car and promised to bring it back in 3 days. Went out and checked the car a day later at 25 degrees outside without starting the car... gauge still sitting at the normal level. No question it's the thermostat. That car will not be driven again until T.stat is fixed in 2 days.

Can start the car in the morning, can start the car at night, when I get off of work, but if I stop at a store,(maybe 15-20 minitues after) and I turn off the engine, it won't start. I have full power. But...


Check the Coolant Temperature Sensor - might be defective (lies to the computer ECM). You see, the coolant temperature sensor tells the ECM (computer) what the engine temperature is... if it's defective (telling the computer that the temp is -40 deg, then the computer will raise the fuel mixture for that temp. If, for example, the sensor is telling the computer that the temp is 200 deg, then the computer will 'LEAN' the fuel mixture.. get my meaning?

Check engine light, but no obvious problems


Good chance it is temp sensor, but have the codes scanned and that will tell you for sure. Another sensor I have run across could be oxygen sensor, sometimes they will make the vehicle run bad and sometimes they dont but in either case is does affect fuel mileage. Dont think either way you need to avoid driving your car unless maybe temp sensor showed overheating problem. But dont wait too long to get code scanned.
