Vandan Plas - Confusing Codes MIL
First of all, I own a 2000 Jaguar Vanden Plas with about 62,000 miles on it.
I am very confused about what my OBCII scanner is telling me. Originally, I was getting a P0105 code MAP Sensor. I replaced the MAP sensor and the car ran good for a few weeks (about 2.5 months ago). Then I started to get a P0521 code which is the Engine Oil Pressure switch. Now in this case, I purchased a new one but due to it's location on the engine, I could never get the old one off. The most that I got done was taking the wire clip off of the sensor and then replacing it once I could not get the actual sensor out of the block. Basically, I gave up and was planning on taking it to a mechanic to do. From there, I cleared the codes through the scanner as well as clearing them by removing the battery cables and touching off the negative to the positive cable.
Since that was done about 2 weeks ago, I have been getting again the P0105 MAP sensor error and when I do clear it, I get the same error again after about 10-15 minutes of running the engine.
So here is my confusion:
1. I am no longer getting the P0521 Engine Oil Pressure error - even though I never actually replaced that sensor - not once since I messed with it trying to get it out.
2. I am however, getting a P0105 warning, again and again, even though I replaced that sensor about 2.5 months ago.
Is it possible that sensor is bad - MAP and I should just replace it? Or does anyone think there is a bigger issue going on here.
Thank you all for your help in advance

There are a few causes that produce a P0105 code... MAP sensor vacuum hose disconnected or plugged....Bad MAP sensor....... Bad TPS...... Damaged or problematic MAP sensor connector....... Damaged or problematic TPS connector....... Damaged wiring,,,,... Short to reference voltage on signal circuit of MAP sensor,,,,,,, Loss of ground to MAP sensor or TPS....... Open on signal circuit of MAP sensor....... Bad PCM
