P026C Dodge Code - Fuel Injection Quantity Lower Than Expected
Quick Answer
The Powertrain Control Module (PCM) uses a Fuel Mass Observer (FMO) Monitor to check the injection correction quantity for exceeding permissible limits and the fuel mass over a period of time. Common causes include Dirty Air Filter, Air Restrictions, Air Leaks. 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.

Code P026C Dodge Description
The O2 sensor output is used to calculate the total system error represented as the quantity which is used for the correction of the O2 sensor signal. This is a 5-wire Wideband O2 Sensor. This sensor operates differently from traditional O2 Sensors. The wide-band O2 Sensor tip consists of two cells that provide different functions, a measurement chamber and a detection chamber with pumping capabilities. The oxygen pumping function is the ability to pump oxygen into or out of the measurement chamber depending on the level of oxygen in the measurement chamber. This function provides wide-band sensing capabilities and is critical for proper oxygen measurement. The controller keeps adjusting the O2 Sensor model until it follows the measured O2 signal (the difference converges to zero).
The described rationality check will detect fuel injection quantity too low or too high, system too lean or too rich, and excessive time to enter closed-loop air/fuel ratio control failure.
