Greetings everyone, I'm going to change my coolant temp sensor to see if this will cure a CEL code P0305 which list this as a possible problem. When I recently replaced my upper and lower intake gaskets I noticed this little sensor on the intake in the front passenger side just behind the alternator. It was small but it had a wire plugged into it. Is this the sensor? If it is I noticed that the place where the wire plugs into it was wobbly does this mean it's damaged? And if so what are the symptoms of it not working properly. Also O'Reilly's list a few different ones for my truck by the # of wires that plug into it. When I unplugged it to do the gasket change I think there were 2 prongs inside which I assume this would mean it's a 2 wire one. Has anyone had to change this sensor? The temp SENDING unit works fine. I have a 98 Ram Sport 4X4 with the 5.9L 360 V-8. Thanks!

 

I am betting you aren't getting a good connection to the sensor. Yes, it is just one wire. Use a pick of some sort to adjust the brass connector to get a good, firm connection.

 

Roger That VW I followed up on the tips you gave regarding my Cylinder #5 misfire postyesterday and since my best friend works for a Dodge dealership as a service manager and is ASE cert he chked on the code and it listed 3 possible causes: 1) bad temp sensor, 2) faulty crank sensor [ which you stated], and 3) loose ground which he states there are 5 total which I know of maybe 3 so he's supposed to show me where the others are.

 

Damn! I was right about something, but yet you posted here before checking with the best friend. You better buy that boy some beer and lunch/dinner and get some knowledge out of his gourd!!!

Let us know the result. The big problem with modern vehicles is they are touchy when it comes to the ground wire.

 

That's a Roger but he's so damn busy that it's quicker and easier to chk with you guys
