Question

2004 Cadillac Deville 4.6L with codes P1133, P1153, and P2763. Please give me the interpretation of these codes.

Answer 1

P1133 Heated 02 sensor bank 1 sensor 1

P1153 Heated 02 sensor bank 2 sensor 1

P2763 TCC (Torque convertor clutch circuit) short to voltage

P1133 and P1153 is for the 02 sensor it is not switch from lean to rich in proper time,This switch rate allows the catalytic convertor to work properly,, incorrect fuel pressure can cause these code, and so can a degraded 02 sensor,, As for P2763 Inspect the engine fuse box on the cover listed as TRANS make sure this fuse has not opend this is a 10 amp fuse, What can cause P2763 is improper resistence of the TCC or the TCC has shorted
