What does it mean when a code p219a is stored?
When a code P219A is stored, it means that the powertrain control module (PCM) has detected an air to fuel ratio imbalance for the bank of the engine which contains the number one cylinder. In order to monitor the air to fuel ratio for each engine bank, the PCM uses data input from heated exhaust oxygen sensors (sometimes called air fuel sensors).
When to set a misfire code p219a?
As a rule of thumb, the PCM will set code P219A if the variation is less than 2% of the crankshafts’ speed; if however, the variation exceeds about 2% of the crankshafts’ speed, the PCM will almost certainly set a misfire code, as opposed to an air/fuel imbalance related code.
