my 2000 gtp is making a ticking noise but goes away after driving for a little while. I took it to auto zone to check out the service engine light and I got 2 codes. first one was p1887 an its saying the ECM has determined that the TCC is not applied but the TCC slip speed indicates that it is either 1-open or short circuit condition, 2-failed trans fluid pressure/manual valve position switch, 3-internal transmission fault. the second code was p0141 which is the H02s12 heater condition (heated oxygen sensor-bank 1 sensor 2). the powertrain control module monitors the oxygen sensor heater. the computer has recognized a failure in the circuit. which is caused by 1-faulty H02s12 (bank 1 sensor 2), 2-poor connection at oxygen sensor, or 3-circuit fuse. the ticking has gotten a little worse over the past month an I was wanting some insite on what I should do any help would b VERY appreciated.
