Did you ever find an answer for your oil light coming on? I have a 2004 PT and my light is doing the exact same thing. I have checked the oil level and it's fine. It did start coming on right before I changed the oil and it did get low before the change. I thought maybe it was one of those things that has to reset itself but it has been going on too long.

To get the codes, move the key from Run to Off to Run to Off to Run within five seconds. It does not always work the first time. (Run is JUST before Start). The code will show up in the odometer - thank your lucky stars for this, since the codes used to get blinked on the engine light. “if you do it too quickly it doesnt work (got to wait to see the odometer light up” and that if you have no codes, the odometer will say “done.” If your code is 522 or 523 that means the Oil pressure sensor has a problem, We suggest you have a mechanic take a look at the problem.
I used the run to off, run to off, run and the message of done came up. Hopefully, everything is okay. Anything else I should be checking???
If it is your OIL PRESSURE lamp that is comming on. the oil pressure sending unit is a good place to start since they frequently fail. The PCM will only set a code for a shorted or open oil pressure switch circuit. It is also a good idea to have the actual oil pressure checked with a known good test gauge. As for retrieving Diagnostic codes, The manufacturer does not supply information for reading codes without a scan tool. The key cycle method of retreiving diagnostic codes does not apply to the newer OBD vehicles.
