EGR Error tells you about the accuracy of the EGR valve’s operation and can help diagnose issues with the EGR system. This parameter is calculated as (actual – commanded) / commanded. A significant EGR error can indicate a problem with the EGR valve, such as a sticking valve or a faulty position sensor. According to a study by the Society of Automotive Engineers (SAE), an excessive EGR error can lead to increased emissions and reduced engine performance. Special Note: If commanded EGR is 0%, EGR error will read: – 0% if actual EGR is also 0% – 99.2% if actual EGR is anything other than 0% – this indicates “undefined” or not applicable. By monitoring EGR error, you can identify potential issues with the EGR system and ensure your vehicle is operating efficiently and with minimal emissions.

7.3 EVAP System Vapor Pressure

EVAP System Vapor Pressure measures the gauge pressure of the Evaporative Emission Control (EVAP) system. Why is monitoring EVAP System Vapor Pressure important? Monitoring EVAP System Vapor Pressure is important because it helps detect leaks or blockages in the EVAP system, which can lead to increased emissions and fuel inefficiency. The EVAP system prevents fuel vapors from escaping into the atmosphere by storing them in a charcoal canister and then purging them into the engine to be burned. Unusual pressure readings can indicate issues such as a faulty gas cap, a cracked charcoal canister, or a leaking EVAP line. According to the California Air Resources Board (CARB), a properly functioning EVAP system is crucial for reducing evaporative emissions and maintaining air quality. By monitoring EVAP system vapor pressure, you can identify potential problems and ensure your vehicle is minimizing its environmental impact.

7.4 Commanded Evaporative Purge

Commanded Evaporative Purge indicates the EVAP purge flow rate requested by the engine computer. What does Commanded Evaporative Purge tell me about my vehicle’s emissions system?

The catalytic converter uses high temperatures to convert pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances. A typical catalyst temperature ranges from 400°C to 800°C (752°F to 1472°F) during normal operation. Monitoring this parameter can help diagnose issues such as a failing catalytic converter, which can lead to increased emissions and reduced engine performance. According to the California Air Resources Board (CARB), maintaining the correct catalyst temperature is crucial for the efficient operation of the catalytic converter and meeting emissions standards. By monitoring catalyst temperature, you can ensure your catalytic converter is working correctly and that your vehicle is minimizing its environmental impact.

7.6 Diesel Particulate Filter (DPF) Data

Diesel Particulate Filter (DPF) data provides information on the filter’s status and regeneration process. What DPF data should I monitor to maintain my diesel vehicle’s emissions system? You should monitor DPF Inlet Pressure, Outlet Pressure, Differential Pressure, and Temperature to maintain your diesel vehicle’s emissions system. The DPF traps soot and reduces exhaust emissions on diesel vehicles. As soot accumulates, the filter becomes clogged, increasing the pressure drop across the filter. Regeneration is the process where the soot is burned off to clean the filter. Monitoring these parameters helps ensure the DPF is functioning correctly. An increase in differential pressure indicates soot accumulation. According to the U.S. Environmental Protection Agency (EPA), proper DPF maintenance is essential for reducing emissions and meeting environmental regulations.
