when coming to a stop. no engine light but have a pending code P0116. this dose not happen all the time but it has happen on 3-4 occasion in the pass week any ideas?

I had a similar problem. It was the crankshaft position sensor. Rpms when dying https://youtu.be/uLget1rw9t0 Crankshaft position sensor location https://youtu.be/eu47LOpbW6o
copy and paste the link. P0116 Engine Coolant Temperature (ECT) Circuit Range ... www.obd-codes.com/p0116
Put a New egr valve on didn't do it for a while. it's done it twice this past week. going to try the crankshaft position sensor I'll let you know how that dose
P0116 - ECT Circuit Range/Performance OBD-II Trouble Code Technical Description Engine Coolant Temperature (ECT) Circuit Range/Performance Problem What does that mean? The ECT (Engine coolant temperature) sensor is a thermistor which changes resistance based on temperature of the coolant in contact with it. The ECT sensor will be located in the block or coolant passage. Usually it is a two wire sensor. One wire is a 5 Volt supply from the PCM (Powertrain Control Module) to the ECT. The other is a ground to the ECT. As the temperature of the coolant changes the resistance on the signal wire changes accordingly. The PCM monitors the reading and determines coolant temperature in order to perform essential engine fuel management. When engine coolant is low, sensor resistance is high. The PCM will see a high signal voltage (low temperature). When coolant is warm, the sensor's resistance is low and the PCM will see a high temperature. The PCM expects to see slow resistance changes on the ECT signal circuit. If it sees a quick change in voltage that isn't consistent with an engine warming up, this P0116 code will set. Or if it sees a lack of change in ECT signal, this code may set. Symptoms There may be no noticeable symptoms if the problem is very intermittent, however the following may occur: MIL (Malfunction Indicator Lamp) illumination Poor drivability Black smoke at tailpipe Poor fuel economy May not idle May exhibit stalling or misfires Causes Potential causes of the P0116 code include: Missing or stuck-open thermostat Bad ECT sensor Short or open on signal wire Short or open on ground wire Poor connections in wiring Possible Solutions If there are any other ECT sensor codes, diagnose them first. Using a scan tool, check the ECT reading. On a cold engine, it should match the IAT reading or should be equal to ambient (outside) temperature reading. If it does match the IAT or ambient temp, check the freeze frame data on your scan tool (if equipped). The saved data should tell you what the ECT reading was when the fault occurred. a) If the saved info indicates that the engine coolant reading was at the coldest exreme (around -30 deg. F) then that's a good indication the ECT resistance was intermittently high (unless you live in Anchorage!) Check for an open in the ECT sensor ground and signal circuits and repair as necessary. If they appear okay, warm the engine up while monitoring the ECT for any intermittent jumps high or low. If there are replace the ECT. b) If the saved info indicates that the engine coolant reading was at the warmest exreme (around 250+ deg.F) then that's a good indication the ECT resistance was intermittently low. Check for a short to ground on the signal circuit and repair as necessary. If it appears okay, warm the engine up while monitoring the ECT for any intermittent jumps high or low. If there are replace the ECT.
Hello Stevieray1,I am just new on this forum ,you are right ,it is not oke to give no reply . The explane from you can help me maby with mine one problem , When the engine is cold and I drive for 0.75 Mile and I stop for the trafficlight the engine is pending and stalls , when I shift in N the engine stays on. During the past months I have replaced the throttlebody, ECT sensor,MAP sensor,EGR valve.Right now I putt on an old EGR Valve and make a hose on the bottom side with an carterventilation filter and blind off the exhaust side . This helps just a bit,but still stalls. I am thinking about the O2 sensors ,when the the sensor is 600 F it starts to work ,and when the engine is above the 40 C the engine goes in open loop , this is very Quickley about an 0.5 mile . I have a snapon solus ,I first gnoe check the ECT sensor whit the snapon reader on data and see how the warming up goes and check the tempratur with the engine is not running. Hello gazaway1, You can try to blind the EGR valve ,and see of the problem is over ,I drive often short distances and I have replaced the EGR valve know for the fourth time,did you mount a EGR valve from Mopar or a different brand ? The one I have now is from Mopar and so far so good ,the one before was a aftermarket one and did it only for 4 months .
been over two months,and no reply back! just like most of the rest,never post if fixed or not.
