What does code P2A3E mean?

Q: What does code P2A3E mean?

Alternative Fuel Delivery Error. P2A3E indicates that the powertrain control module has detected a discrepancy in the alternative fuel delivery system, meaning the actual fuel pressure or flow does not match the commanded value within an acceptable margin. The computer monitors pressure sensors and injector feedback to determine that the alternative fuel (such as compressed natural gas, liquefied petroleum gas, or ethanol) is not being delivered as expected, which can affect performance and emissions.
