What does the code p219a stand for?
What does the code p219a stand for?
In the case of code P219A, the code refers to an issue that causes a rich condition (too much fuel relative to air) in one or more cylinders on Bank 1, as opposed to an issue that causes a lean condition (too much air relative to fuel) in one or more cylinders on Bank 1.
How much does it cost to diagnose a p219a Chevrolet?
The cost of diagnosing the P219A CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. The Fuel Trim Cylinder Balance diagnostic detects a rich or lean cylinder to cylinder air/fuel ratio imbalance in each bank.
When to use p219a for fuel ratio imbalance?
If the PCM detects an imbalance in the air to fuel ratio for a particular bank of the engine, a code P219A will be stored and a malfunction indicator lamp (MIL) may be illuminated. Most vehicles will require multiple ignition cycles (with a failure) for MIL illumination.
Why is the p219a Bank 1 OBD code intermittent?
The code may actually be more difficult to diagnose if the PCM enters readiness mode at this point, because the code is intermittent. The condition which caused the P219A to be stored may need to worsen before an accurate diagnosis can be made. If the code is restored, continue with the diagnosis.
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).
