Q: What does code P2AB0 mean?

Particulate Matter Sensor Processor Performance. P2AB0 indicates that the particulate matter (PM) sensor's internal processor is not performing as expected, so the engine control module (ECM) cannot trust the sensor's readings. The ECM monitors the processor's calculation speed and signal integrity, and when the processor fails to respond correctly or produces implausible data, it stores this code.
