1996 Chevrolet Tahoe O2 Sensor Codes P0153, P0154, P0155, P0307 and P0115 - How to Reset and Diagnose

Model: 96 Tahoe Fault Code: P0200 Posted: 2005-12-14 10:55

Just returned from Iraq. Before departure, I replaced both front oxygen (O2) sensors on my 1996 Chevrolet Tahoe. Despite the replacement, I'm still receiving these diagnostic trouble codes: P0153, P0154, P0155, and P0307. Additionally, I have a P0115 code. The misfire (P0307) was present prior to any of the O2 sensor issues, suggesting it may be unrelated. I'm currently attempting to reset the system by disconnecting the battery. I'll update later if this resolves the issue. I plan to visit an authorized repair shop (like AutoZone) for a full diagnostic check. Thanks for any advice or insights on these codes in a 1996 Tahoe.
