Volvo All Engines (2010 Emissions) Fault Code: SPN 5443 FMI 13 PID: PPID 329 Aftertreatment 1 Hydrocarbon Dosing System - EcuForce Truck (2024)

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).

Okay, The spn 5443 fmi 7 is mechanical system not responding with the aftertreatment hydrocarbon dosing system. There is a few different things that can cause this. One is a plugged 7th injector. There is a flow test kit to test them, They are cheap and easy to replace.

Engine Injector Faults (MID 128 SID 1 – SID 6)

Mechanical system does not respond correctly. Resistance too high in injector.

This fault is for high soot load in the DPF . Possible causes for this fault to come up are :-Low engine temperatures-Low engine load-Unnecessary excessive idle time .

The location of this module is on the driver's side of the engine. It is located underneath the starter on the rear side of the fuel filter housing.

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.

FMI stands for failure mode identifier—this part of the fault code tells you what type of problem your truck has. For example, in the fault code SPN 3226 FMI 13, the SPN number 3226 tells you the problem is with the SCR outlet NOx sensor and FMI 13 tells you that the signal from the part is unavailable.

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).

A Suspect Parameter Number (SPN) is a specific code used in the automotive industry to identify and diagnose faults codes in electronic control units (ECUs) within vehicles. These codes are integral to the CAN Bus system, facilitating precise monitoring and troubleshooting of vehicular systems.

What is ECM on Volvo? ›

The ECU, often referred to as the engine control module (ECM), is essentially the brain of your Volvo's engine. It constantly monitors and adjusts various parameters, such as fuel injection, ignition timing, air-fuel mixture, and more, to ensure smooth operation.

The coolant temperature sensor on Volvo models with a normally aspirated 5-cylinder engine is mounted in the coolant housing on the right side of the engine, below the thermostat. It monitors the engine coolant on the engine side of the thermostat.

A P2118 code refers to the throttle actuator control motor current. This OBD II code may be displayed with other throttle position sensor codes. A throttle actuator control motor electronically controls drive-by-wire systems on cars that have the feature.

A logged P0638 code means that the PCM has detected that the throttle actuator is not in the right position. A faulty throttle body assembly, defective throttle position sensor, wiring issues, and a faulty PCM can trigger this code.

Codes P0410 through P0419 indicate problems involving general malfunctions of the secondary air injection system that range from potentially faulty parts that require replacement to specific issues involving open or shorted switching valve circuits or other malfunctions involving faulty components such as relays, ...

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.

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.

Diesel engine aftertreatment system is an important component for vehicle powertrain systems, which is usually used to eliminate the NO_x and the particulate matter (PM) in Diesel engine emissions.

The HC doser is located downstream of the exhaust gas recirculation (EGR), which is the inlet of the DOC. After dosing, the diesel droplets are directly injected into the exhaust flow. These droplets continuously evaporate and are converted to gaseous hydrocarbon species in the gas phase.
