    i'm sorry, let me rephrase my problem. when the leganza warms up, and i put it into drive the oil light comes on. we have replaced the oil pressure switch yesterday. it seems like when the oil thins and the car is warmed up, the oil light comes on. we have changed the oil, filter is fine, and we have replaced the switch. what else could be keeping that light on?

As long as you have a load on the engine, there is an oil pressure so it turn the light off. At idle and first start there is not enough oil pressure to turn off the switch. To check if you lose oil pressure, look around the oil filter, if the seal is not tight, it may take some time for oil pressure to build up, that why you have this problem.
If you don't find any oil leak, try to clean the dirt surrounding the oil pressure switch contact, if it is not improve then have oil pressure switch replaced.
Before a replacement, make sure you don't lose coolant and check oil level to see if you have too high of the oil level which is an idication of a head gasket problem. Hope this can help.

You oil light problem is due to your oil pump starting to fail. You need to replace this and it will take care of that for you. As far as the CEL goes the p1627 refers to your PCM (powertrain control module). I would suggest that you pull the plug on the PCM and make sure it is clean and plugged in tightly. Inspect the harness connectors for backed out terminals or damaged terminals. Plug it back in and reset your CEL and see if the code comes back on. If it does it sounds like your PCM is going out and will need to be replaced. Good luck and thanks for using FixYa!
