I changed the temp senseor on my Ram and when I put it back together it would not start. The gauges will not work and sometimes the odometer flashes then other times it says no bus. No fire but will turn over.

Codes are: p0505, p0123, p0118, p0113, p0463 and p1492

Anyone have any ideas?

Thanks

 

Is the temp sensor the ONLY thing you did? Just remove the old one, and install the new one?

 

Yeah, I had to unbolt the alt to get to it. once I replaced it I put all back together and now wont start.

 

Check and make sure everything is hooked up correctly at the alt. There is a ground there that is kinda important.....

If you are getting no bus errors, you missed a trick somewhere.

 

I hooked up the ground and the plug on the back.

Not getting the no bus now but gauges still not working and still no spark.

 

Where are you checking for spark, and how?

 

With screwdriver and plug wire while turning it over.

 

Pull one of your sparkplugs, stick it back in the wire, and ground it on the intake somewhere. Hold it in place with a stick of some sort. (non-conducting please....) see if you get spark that way. Also test in the same manner, with the coil wire.

Is your temp sensor plugged back in??

 

I will try that.

I plugged the temp sensor back in. The plastic on the old one broke when I disconected it, you think the plug may be bad? That wouldn't keep it from starting would it?

 

It should still have spark, but, it may not wanna start....
