Welcome Aboard !!! Which car, model, year, engine? Please update your profile.

B 1312 refers to A/C high side sensor problems; P 1483 is a generic cooling system performance code.

Bookmark this and use it to define codes when you post them. Thanks.

98 DeVille

32 litre northstar

Could it be because I did something wrong when I recharged the a/c and if so if I clear the code will it solve my overheat problem?

==============
B1312 - High Side Temp Sensor Open Circuit
there are temperature sensors for the refrigerant on BOTH the HIGH pressure side and the LOW pressure side -
this code means the sensor is either unplugged - or it is broken -

Could it be because I did something wrong when I recharged the a/c
it IS possible that you unplugged the sensor - or knocked into it and broke it -

if I clear the code will it solve my overheat problem?
NO - for a couple different reasons -

first - clearing a code does NOT fix or cure anything - ever -
it simply erases the code from the computer's memory - temporarily -
and that code WILL constantly re-appear until the issue is FIXED -

second - this code points to a HVAC issue -
and has nothing to do with overheating -

==========================

regarding the overheating -
it COULD be many many different things -
and it will require a LOT more - VERY specific information - to try to diagnose the problem -

things to check -
how hot is "overheating" -

describe - IN DETAIL - the exact sequence of overheating -

does the temp raise sitting at a stop light -
does it drop when you start moving -

coolant level - when FULL - the serge tank should be about 1/2 full -

does the cooling system maintain pressure when hot -

do the electric cooling fans both operate -

does the PURGE LINE have a constant - gentle flow of coolant going into the serge tank -

if you turn the cabin temp up to 90* -
do you get really - REALLY hot air from the vents -
