Bad sensor?

Low coolant?Bad sensor?
there is a light we dont know what it means
its right next to the valve cover on the driver side behind the coolant sensor
Either coolant is low or the sensor in the reservoir is stuck with dirt. Clean the reservoir with soap and water
Check your overflow bottle to make sure there is adequate coolant in there. If there is, the coolant level sensor is faulty and must be replaced.
Your check engine light just dosent check only your coolant. It's a light for your OBD (ON BOARD DIAGNOSTIC) system. That light reads numorus sensors. you will have to get a code reader hooked up to your car. if i would guess, it would probly be your o2 sensor.(oxygen sensor) --------------------------------------- For what it's worth, make sure that you tighten your fuel cap securely. If it's loose, it will "throw" a code. Most auto parts stores will read the codes for you at no charge. FriPilot
how to check fuse for horn in a 1998 Pontiac sunfire
TAKE THE PASSENGER SIDE HEAD LIGHT OUT. YOU WILL SEE IT IN THE FENDER.
I have a 1998 Sunfire and am getting my coolant sensor replaced today. I am told by the dealer that it is located in the housing of the plastic reserve bottle. Basically I am told you have to replace the entire bottle. Hope that helps? I just unplugged mine it was a lot cheaper
it probably needs an O2 sensor they range from about 40-90 dollars
what is the specification of the cram shaft of sunfire 1998, motor 2.4
Fill the RADIATOR with coolant. If it is full the sensor needs to be removed and cleaned. Air bubbles in the system will cause this. I'm told it is very difficult to remove air in the coolant in Sunfires, & sometimes raising the front of the car with a towtruck is the last resort. Ramps under the front tires might work. It took us 2 visits to the mechanic to get all the air out. I have had this problem with my 1997 Sunfire. Its a 2 door Coupe. The engine overheated, and the coolant light came up. I almost had my head gasket repaired, and come to find out, the coolant cap was wore out, causing the coolant to leak, causing the light to come on, and the engine to overheat. I had the same problem with my 2.4 1998. After serveral trips to the mechanic, replacing the thermostat twice, replacing the pressure hoses and countless gallons of coolant I found out the water pump was bad. Get this looked at ASAP!!! I waited a few months until I was able to afford the pump replacement (cost me $1100). This also included replacing the timing chain, which any mechanic will suggest and I would agree.
