hello all.... i finally got around to getting a motorcraft tps sensor and guess what tps code is gone! the autozone wells replacement tps(246) had almost the exact opposite alignment of the motorcraft and was causing incorrect readings. installed the new tps and life was great. then the c.e.l. light came back on. i went to a.z. and had it scanned again thinking it was the same old thing.....this time i got 2 new codes which are as follows p1131, and po133, searched the archives and found a post from tony on there and it gave me some things to go look for but the other guy was getting a different second code than i am and i was wondering if anyone knew if or what may be wrong when you get these 2 codes together....thanks
