Need to change the engine coolant temp sensor, Where is it and what are the steps to changing it.

Hooking up a factory or professional scan tool an looking at coolant temp sensor data PID'S ( parameters) in engine sensor data . What's the coolant temp. sensor reporting to the PCM/ECM . Also checking with a Non-Contact Infrared Thermometer

What's the real temp of the engine. You have no idea what your doing , take it to a qualified repair shop.

What diognostics say its a sensor ?????? No diagnostic's ever tell's you it's a sensor . You as a technician would need to prove that by testing electrical circuits , viewing coolant temp sensor . Hooking scan tool and trying to command the gauge with by directional control . The temp gauge not showing any temp. ? No movement ? Engine Coolant Temperature Gage Inaccurate or InoperativeStep Action
Yes
No
Schematic Reference: Instrument Cluster Schematics
1
Did you perform the Instrument Cluster Diagnostic System Check?
Go to Step 2
Go to Diagnostic System Check - Instrument Cluster
2
Install a scan tool.
Turn the ignition ON, with the engine OFF.
With the scan tool, perform the Lamp and Gauge Check in the IPC Special Functions list.
Does the engine coolant temperature gage move up and down when commanded?
Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 3
3
Replace the IPC. Refer to Instrument Cluster Replacement .
Did you complete the replacement?
Go to Step 4

4
Operate the system in order to verify the repair.
Did you correct the condition?
System OK
Go to Step 2
Would hate for you to replace the coolant temp sensor an find out that's not the problem ! Does the vehicle start an run good ,trans mission shift good ? If so it's not the coolant temp sensor .
Engine Coolant Temperature Gage
The ECM sends coolant temperature as determined by the coolant temperature sensor to the BCM via CAN serial data. The IPC displays the engine coolant temperature with the gage when the BCM sends a class 2 message to the IPC indicating coolant temperature percentage. The engine coolant temperature gage defaults to cold (0°) or below if:
• The ECM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of class 2 communications with the BCM.
• The BCM detects a loss of CAN communications with the ECM.

code p 0480 refers to engine coolant blower motor 1 ---circuit malfunction=== causes ---wiring ---engine coolant blower motor ---ECM
code p 0116 refers to engine coolant temperature (ECT) sensor ---range b/performance problem ====causes coolant thermostat---poor connections---wiring---ECT sensor

Probable needs a coolant temp. sensor. had this problem on 97 cherokee new coolant temp sensor fixed it. I would suggest changing the thermostat also.

You did not change the coolant temp sw. you change the ETC which sends a signal to the cpu. It looks just like the temp sw. Look on the driver side head and I believe you will see another one there or look the engine over for another sw just like the one you changed. Not sure what size engine you are asking about.

timing belt is off by a tooth or two. you probably didn\'t have to replace the coolant sensor; that code sets whenever the sensor is disconnected and the ignition is turned on; and it needs to be reset by disconnecting the battery or with a code reader. anyway, the crank/ cam sensors are out of sync. if you\'ve got the twin cam engine, they are a royal pain to get the belt to lay properly on the two cams.

drain coolant, locate thermostat housing on engine at end of lower radiator hose, loosen clamp to remove hose from housing and disconnect sensor...remove bolts and carefully remove housing from engine. Inspect parts and replace anything worn (such as swollen hoses, damaged housing, defective temp sensor). Sealant is not necessary to re-install the thermostat.

on your car are two sensors one is an engine temp sensor the other is a coolant temp sensor
change the coolant temp sensor that is what goes bad most of the time when the water gets to 210 degrees the coolant temp turns on of that is working change the radiator fan relay

change coolant temp sensor. it will be reporting wrong leading to the misfire.

This might be what we call vapor lock try driving with your gas cap off and see if it still quits under the same conditions.
