P1295: Multiple Faults on Bank 1 (Right)
P1295 indicates that the powertrain control module (PCM) has detected multiple faults on bank 1 (right side) of the engine. This code is often triggered by issues with the fuel injectors, ignition coils, or wiring harness on that bank. It can also be caused by a faulty oxygen sensor or a vacuum leak. The PCM monitors the bank for misfires, fuel trim deviations, and other anomalies, and when multiple faults are present, it sets this code.
