2004 Acura TL P0157 P0158 P0159: Single Oxygen Sensor Issue in Bank 2 Sensor 2
Hi everyone, I'm experiencing fault codes P0157, P0158, and P0159 on my 2004 Acura TL. All three codes point to the same location: Bank 2, Sensor 2 (B2S2). My question is whether this indicates three separate oxygen sensors or just one sensor at that position. Can someone confirm if it's a single sensor and clarify its exact location in the engine system?
Before replacing any sensor, make sure you've checked the wiring harness and signal voltage. These codes typically point to the same component — Bank 2 Sensor 2 (B2S2). There's only one oxygen sensor at that location, so it's likely a single faulty unit rather than three separate sensors.
