I have an engine coolant sensor trouble code and need to replace it

13, 14, 27, 28, 31, 42, 46

I did replace the coolant sensor 14 and 15 relates to the coolant sensor.I couldn't find another one on the engine.I do have a dash light that lights up if overheating

That is why I say the transmission has something to do with it 27 and 28 are gear switch problem, 31 is park/ neutral switch42 is est circuit open or grounded and 46 is power steering pressure switch and 14 is cts signal low this is all in mitchell repair manual 92 Buick Century Special

I am having a mechanic run a computer scan on it anyways this will tell me closer to as what is wrong.

Took car to mechanic today he checked it with computer but computer didn't work at all. He said probrably have a broken wire or bad on board computer going to check wires on it tomorrow.

Saturntech9 we have success I bought a new computer yesterday already flashed mechanic installed it today. Took about an hr removed underpanel and glove compartment to get to it. Moved the prom to new computer reinstalled same. Started car no check engine light on and car purring like a kitten. Ran computer check on car found NO bad codes listed. Took car for 25 mile ride runs like it used to. Mechanic charged me only $60.00 for computer install and nothing for troubleshooting it 2 hrs a day for 2 days.I told him you got my business always. Thanks for your help and ideas I have learned alot just by coming on here. He was right on when said go with a new computer first then if nothing works check for broken wires. New comp already flashed cost me $79 at autozone
