AutoCodes – Generic – P219E

P219E Code - No. 3 Cylinder Air-Fuel Ratio Variation

Quick Answer

The Powertrain Control Module (PCM) detects the imbalance amount from the sizes of the 0.5-order and 1.0-order components compared to 0.8-order excitation input by the fuel injection to determine the air/fuel ratio variation between the cylinders. Common causes include Faulty fuel injector, Fuel rail clogged, Intake manifold air leak/clogged. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: P219E indicates No. 3 Cylinder Air-Fuel Ratio Variation.
Common causes: Common causes include Faulty fuel injector, Fuel rail clogged, Intake manifold air leak/clogged.
Severity: High - diagnose this code as soon as possible.

Code P219E Description

The Powertrain Control Module (PCM) detects the imbalance amount from the sizes of the 0.5-order and 1.0-order components compared to 0.8-order excitation input by the fuel injection to determine the air/fuel ratio variation between the cylinders. The obtained components are used to learn the fuel coefficient of each cylinder and performs the imbalance reduction control. If it is not possible to suppress the variation even if the imbalance reduction control is performed; resulting the imbalance amount is large and the fuel coefficient is a specified value or more, the PCM detects as imbalance failure and the Diagnostic Trouble Code (DTC) will set.
