2000 jeep Cherokee Trouble Code 118 -Engine Coolant Temperature Sensor input above maximum acceptable voltage What causes this and how do you fix it?
replace the sensor.
What type of coolant sensor? The below answer is for the coolant LEVEL sensor. The coolant TEMPERATURE sensor on my vehicle is located just next to the thermostat housing. On the front top center area of the engine just behind the radiator. Follow the coolant hoses if you have trouble. On my 1995 Jeep Grand Cherokee the sensor is located on the top of the plastic coolant reservoir tank. Look for a small (2-wire?) electrical…
Locate and remove old coolant temperature sensor (disconnect electric connector and you should be able to loosen sensor with an open end wrench; if it's too tight, use a flared end wrench to break it loose). Catch coolant that spills out after sensor is removed, properly dispose of old coolant. Install new sensor in reverse order. Top off coolant. Clear trouble code & test drive vehicle to ensure vehicle performs to spec.
I just replace the water pump on a 1992 Jeep Cherokee Laredo but it still seems to over heat and coolant still blowing out everywhere how do i trouble shout this issue?
A thermostat stuck in the closed position is very common in overheating problems. Simple to check: Remove the radiator cap and start the engine. Look through he filler neck to see if you see the coolant circulate when the engine reaches normal operating temperature. If you don't see water circulate, more than likely the thermostat is stuck.
1999 Saturn that won't start It ran fine yesterday Today it won't start you get a puf of white smoke from the engine and dark smoke out the exhaust Car Turns over but doesn't start Any ideas for cause?
Check for trouble codes with a scan tool. I worked on a Saturn that had corrosion on the coolant temperature sensor connector which caused the computer to see too low of temperature and it added excessive fuel to the mix. The car barely ran, hads lots of smoke, the gauge on the dash was erratic and a coolant temperature sensor code was stored in the PCM.
