My truck just threw this code p0532. The tech section said it means "ac pressure sensor low". I just had my ac system recharged & checked for leaks (dye added). What does this mean? This is my first dodge/diesel. TIA

 

Could be an old code from when the a/c freon was low. Also check the wiring near the a/c pressure transducer on the lower side of the engine behind the comperssor. Not for sure on your year or not, but it has been a problem area.
