did it change for the better or worse? if it changed for the better it could of been bad.
Bad coolant sensor or faulty wiring to the sensor.
there is a sensor in the bottom of the coolant bottle, change this and you should be o.k. tap the sensor with a screw driver it will go out uts just stuck
Yes, a faulty coolant temp sensor can do that.
Bad sensor? == ==
Low coolant or a defective sensor
A coolant sensor could be a liquid level sensor and the other is a temp sensor OR The coolant is different temperatures at different places inside the engine and way way cooler when it comes out of the radiator so where the two sensors are mounted can cause difference's. OR they are two different pieces and calibration will not be identical and they will produce slightly different readings.
Coolant Temperature Sensor
The coolant level sensor is faulty.
i have a 95 impreza and i just got the same dtc ( po115) along with po114 wich was my 02 sensor. So most likely the fuel loop problem is being caused by the coolant sensor and once that is replaced the other problem should subside. Similar to my 02 sensor dtc, wich i believe is being caused by the excess gas being used from the faulty coolant sensor
bad sensor. Or if you did have low coolant at one point the light tends to stick on take it to a body shop. if its the sensor it runs about 60 bucks
That would depend on which temeprature sensor you are asking about. Is it the coolant temperature sensor or the air charge tenerature sensor you are asking about?
If it is a temperature sensor, it is usually located on the top of the engine near the thermostat. If it is a "low coolant sensor", then it is located in the radiator (it will be the only item in the radiator that has a electric wire going to it) Either way, you would drain the coolant enough to be below the sensor, and then remove it and replace it with a new one. They are usually under $10-$20
