2 water coolant sensors?
so, ordered a coolant temp sensor from the dealer and i thought it would have a plug on it, it does not. instead i get this small little sensor that has a little metal extension with a hole in it and my mechanic says it should have a plug like this one.
https://www.carid.com/original-equip...SABEgIKj_D_BwE, which one do i replace? i'm going to get the one i posted a link for, but do i replace both or just the one with the plug that hooks up to the ecu? |
The little one is for the coolant temp gauge. I call that one the coolant temp sensor.
The one with two prongs is the Engine Coolant Temp Sensor (ECTS) that connects to the ECU. A failing ECTS will send confusing readings to the ECU and usually result in hard to start conditions. |

question is, will it also cause a stalling issue and spray to much fuel, as you know i've had that problem for awhile. no codes right now, thanks
Make sure fuel rail is torque specd and the intake manifold for vacuum leaks |

I have a 1995 and It will run fine until it hits operating temp it will stall and does'nt want to start back up until it sits for quite a while could this sensor be the cause . Thanks .

Replace both of them they're cheap enough..

Just to be clear, and I'm not trying to be a smart-a**, know-it-all 'er nuthin, but ...
This is what's commonly known as the coolant temperature sending unit and allows the dash temperature gauge to work. It's failure or malfunction will not impact engine operation or drive-ability. It'll just make your temp gauge quit working: https://cimg4.ibsrv.net/gimg/maxima....b4ab543809.jpg This is the ECTS (engine coolant temperature sensor) that communicates with the ECU and that can, upon it's failure or malfunction, impact engine operation and drive-ability: https://cimg4.ibsrv.net/gimg/maxima....0422dd4d6a.jpg |
Maxride, sounds like you need to replace your ects sensor. It's fairly inexpensive.
It adjusts electrical resistance in ohms as the engine warms up. The ecu uses that information to adjust how much fuel to feed the engine. The ects might be telling the engine that its 40 below. So the mixture might be way too rich. Even corrosion on its contacts might do that. |

My 95' has the same symptoms. I figured everything that I have to touch is getting replaced.
Here's my parts list: egr guide tube egr valve egr bpt valve egr solenoid fuel pressure regulator fuel filter all new gaskets fuel injectors fuel injector o-rings blow by hoses egr temp sensor already replaced ects sensor o2 sensors already replaced (need to have the tested) Installed brand new exhaust from the headers down. Cat has failed and I'm getting a rattle from it. This cars been a pain since last summer... |
Skywalker, that's quite a list.
I would have the injectors rebuilt at InjectorRX.com Great fast service. I cleaned the egr guide tube and system like I did. I tested the solininids. No sense replacing good ones. They are not cheap. You are on the right track though. You car will run well for a long time once you are done. |
Last summer I went ahead and replaced the front/rear valve cover gaskets. Slapped it all back together and my car ran like ****. It's been running like **** since. Thought my coil packs went out so I had replaced those. Problem continued. This time I figured instead of guessing or wasting time I'll just replace everything I touch. Prior to the valve cover job the vehicle had 0 issues. Well it leaked out the valve cover.
Now that I have all these parts I just need to find time between work and family to get it done. Good luck to everyone that's experiencing these idle/fuel/stalling/sputtering issues. |
