Description
Reviews (0)

The Aftertreatment Hydrocarbon Dosing Module contains three non serviceable valves, the Aftertreatment Fuel Shutoff Valve, Aftertreatment Purge Air Valve and Aftertreatment Hydrocarbon Dosing Valve, and a serviceable Aftertreatment Fuel Pressure Sensor.
During DPF regeneration the Engine Control Module (ECM) sends a voltage signal to activate the Aftertreatment Fuel Shutoff Valve to the open position. This allows fuel to flow into the Aftertreament Hydrocarbon Dosing Module. The Aftertreatment Fuel Pressure Sensor monitors the fuel pressure value and sends a reference signal to the ECM. The ECM then sends a PWM signal to the Aftertreatment Hydrocarbon Dosing Valve that regulates the amount of fuel delivered to the Aftertreatment Hydrocarbon Doser through the air/fuel line.
During Air Purge operation the Engine Control Module (ECM) sends a voltage signal to activate the Aftertreatment Purge Air Valve open. This allows air pressure to flow into the Aftertreament Hydrocarbon Dosing Module. The ECM then sends a PWM signal to the Aftertreatment Hydrocarbon Dosing Valve that allows purge air pressure to be monitored by a signal from the Aftertreatment Fuel Pressure Sensor to the ECM.

Conditions for diagnostic trouble code (DTC):
1) Air pressure, not within expected range

Observable symptoms
1) Regeneration not possible

Probable cause
1) Low air pressure
2) Aftertreatment Hydrocarbon Dosing Module
3) Inconsistent Air pressure
4) Fuel line(s), Leakage
5) Aftertreatment Fuel Pressure Sensor

FAQs

What is aftertreatment 1 hydrocarbon dosing system? ›

The Aftertreatment Hydrocarbon Injector (AHI) System is a component of the Emissions Aftertreatment System (EATS) that monitors and controls fuel injection into the Diesel Oxidation Catalyst (DOC) to regenerate the Diesel Particulate Filter (DPF).

Where is the aftertreatment fuel pressure sensor located? ›

It will be on the driver's side of the engine towards the rear. You'll see an air line attached to the purge air actuator. The actuator is plumbed to the aftertreatment shutoff manifold. The shutoff valve and pressure sensor are screwed in from the bottom.

What is the aftertreatment 1 diesel exhaust fluid controller? ›

Aftertreatment 1 Diesel Exhaust Fluid Controller The Diesel Exhaust Fluid Controller has the ability to read attributes of the SCR system, including but not limited to, diesel exhaust fluid level, diesel exhaust fluid temperature, diesel exhaust fluid quality, and diesel exhaust fluid dosing rate.

What is the code for oil pump malfunction? ›

The oil pump is part of the fuel pressure oil system that forces oil into the lubrication system to maintain the right amount of pressure under certain driving conditions. Any problem with the oil pump will cause the powertrain control module (PCM) to log a P06DD code.

What is the error code for transmission control module? ›

Error code P0700 signifies that a malfunction has been detected in your vehicle's transmission controls. Most modern automobiles feature a specific control module as it relates to the vehicle's automatic transmission. This module is known as the Transmission Control Module (TCM).

What is SPN in engine error codes? ›

SPN is short for suspect parameter number. It identifies which electrical circuit, part or component of your truck isn't working properly. FMI stands for failure mode identifier—this part of the fault code tells you what type of problem your truck has.

Where is the temperature sensor on a Volvo engine? ›

It is mounted in the coolant housing on the right side of the engine, below the thermostat.

What does a hydrocarbon doser do? ›

The EcoFit Hydrocarbon Dosing Systems inject unburned fuel upstream of the Diesel Oxidation Catalyst or combination Diesel Particulate Filters. This process helps in the active regeneration of the Diesel Particulate Filter.

Know More ›

What is the purpose of aftertreatment system? ›

An aftertreatment system is a method or device for reducing harmful exhaust emissions from internal-combustion engines. In other words, it is a device that cleans exhaust gases to ensure the engines meet emission regulations.

What is the hydrocarbon dosing valve? ›

The Hydrocarbon Doser Valve controls the amount of fuel injected into the exhaust upstream of the Diesel Oxidation Catalyst (DOC) to allow efficient regeneration of the Diesel Particulate Filter (DPF).

What is aftertreatment diesel system? ›

Aftertreatment systems basically clean up the engine exhaust before it leaves the vehicle. We call this “scrubbing emissions from the exhaust gasses”. Every truck has exhaust, it just needs to be clean before it leaves the vehicle. Heavy-duty truck emissions controls were also phased in gradually.
