What does a p219a Bank 1 OBD code mean?

What does a p219a Bank 1 OBD code mean?

Although generic, the exact repair steps may vary depending on year, make, model and powertrain. 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.

What does p219a mean on air fuel imbalance monitor?

P219A Meaning The air fuel imbalance monitor is designed to detect differences in the air fuel ratio between cylinders per engine bank . The test fails if the air fuel ratio difference per cylinder is greater than a calculated amount.

What is the purpose of the p219b cylinder imbalance Bank 2?

P219B Air-Fuel Ratio Cylinder Imbalance Bank 2 – the purpose of the cylinder imbalance detection monitor is to detect an air/fuel ratio imbalance between the cylinders across an entire cylinder bank. Athough it does not indicate as such, this fault will set because a specific cylinder on this bank is out of balance with the other cylinder.

What are the common causes of code p219a?

What are the common causes of code P219A? Some common causes of code P219A could include one or more of the following- Damaged, burnt, shorted, disconnected, or corroded wiring and/or connectors in the fuel injection and/or ignition systems Defective or worn upstream (located before the catalytic converter) oxygen or air/fuel ratio sensor

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).

What does a p219b Bank 2 OBD code mean?

Although generic, the exact repair steps may vary depending on year, make, model and powertrain. When a code P219B 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 does not contain the number one cylinder.

P219A Meaning The air fuel imbalance monitor is designed to detect differences in the air fuel ratio between cylinders per engine bank . The test fails if the air fuel ratio difference per cylinder is greater than a calculated amount.

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.
