Ford Explorer 96 Model P1132 and P1152 O2 Sensor Fault Codes - Need Help Diagnosing
I recently received O2 sensor-related trouble codes PO155, P0141, and P0135 on my 1996 Ford Explorer with approximately 117,000 miles. While it's uncommon for three O2 sensors to fail simultaneously, I've now noticed new fault codes: P1132 and P115
Considering the vehicle is over 25 years old and has not had a catalytic converter replacement, it's highly likely that multiple O2 sensors are failing due to age and exposure to high mileage. Replacing all affected sensors may be necessary for proper emissions and engine performance.
