A stored P20BA code means that the powertrain control module (PCM) has detected an abnormal voltage that is outside the normal range of expected values on the control circuit for the onboard reductant heater, indicated by the letter A. This designation is used when multiple reductant heaters are in use, refer to manual vehicle repair to ...
Oct 15, 2021 · The controller determines the exact timing of diesel exhaust fluid injection by keeping track of the oxygen sensor, NOx sensor, and the exhaust temperature sensor, among others. The reductant heater is a component that is used to prevent diesel exhaust fluid from freezing or crystallizing in low temperatures.
Always store reductant at a temperature be-tween -11°C and 30°C (12-86°F). IMPORTANT! In order for the emission control to meet the emission requirements set by the public authorities, the reductant should be specified in accordance with ISO 22241. IMPORTANT! Cleanliness is very important when working on the reductant circuit. Clean thorough-
Paul Scott Some diesel vehicles use urea. Urea is used in several new diesel powered vehicle models as a post-combustion emission suppressant. The rationale behind the technology is the control of nitrogen oxide (NOx) concentrations in the exhaust gases of compression ignition (CI) engines. NOx is a natural byproduct of CI systems and a major contributor to air pollution.
