ISUZU 4JJ1 Engine P0118 Engine Coolant Temperature Circuit High Input

hitachi isuzu 4jj1

The engine coolant temperature sensor is installed near the thermostat housing. The engine coolant temperature sensor is a variable resistor and measures the temperature of the engine coolant. This sensor has a signal circuit and a GND circuit which are connected to the ECM. The sensor resistance is high when the engine coolant temperature is low, and the sensor resistance decreases as the engine coolant temperature increases. The ECM detects a high voltage when the sensor resistance is high and a low voltage when the sensor resistance is low. If the ECM detects an excessively high signal voltage, the DTC is set.

Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide

Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide (2)

Here is the instruction show you guide on how to oxidation catalyst air clean for Detroit GHG17 engine.

 

Before performing this service routine, the cause of the DOC plugging should be found and corrected. Typical DOC plugging causes are vehicle duty cycles that are: stop-and-go, have excessive idle time, have stationary PTO operation, or have a hardware issue with the engine or vehicle. Perform the “ATD Checklist” to review these possible causes and correct them before running this service routine.

 

The Diesel Oxidation Catalyst (DOC) air cleaning will remove soot that has built up on the face of the DOC. Air cleaning the DOC will reduce the aftertreatment inlet pressure, allowing for a parked regeneration to safely run without damaging the engine.

DOC air cleaning kit DSN0ATZ16002 is compatible for use on EPA10 1-Box, GHG14 1-Box, GHG17 1-Box, Gen 5 1-Box (with dual DOC) and 2016-2021 MDEG 1-Box aftertreatment systems. You will also need an air gun with a six-inch tip and shop vacuum equipped with a dust bag to capture soot removed from the aftertreatment. A shop vacuum with a 2 ½ inch diameter hose will provide the best sealing around the inlet reduction cone.

Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide (1) Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide (2) Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide (3)

 

Check as follows:

WARNING

PERSONAL INJURY

Use caution when handling and cleaning the Diesel Oxidation Catalyst (DOC). Personal protective equipment and clothing in accordance with all applicable federal, state and local laws or regulations should be used. Contents of the ash and soot removed from the DOC may be classified as a hazardous waste under federal, state and/or local laws or regulations. Hazardous wastes must be handled and disposed of in accordance with all applicable federal, state and local laws or regulations.

 

 

1 Remove the 1-BOX™ aftertreatment from the vehicle. Refer to section “Removal of the 1-BOX™ from the Vehicle” .

2 Remove the outboard heat shield (1) from the 1-BOX™ configuration by disengaging the folded flange on the top of the outboard heat shield.

Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide (4)

3 Remove the four mounting bolts (2) from the inboard heat shield (1). Slide the inboard heat shield down allowing better access to the inboard Diesel Particulate Filter (DPF), V-band and flat band clamp.

Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide (5)

Note : Record the orientation of the bands and clamps. These components need to be installed in the same location.

4 Loosen the outboard V-band and flat band clamps on the outboard DPF.

12 Attach the DOC cleaning cone (1) to the outboard DOC and hand-tighten clamp.

13 Attach the shop vacuum hose to the aftertreatment reduction cone (3).

 

CAUTION

EYE INJURY

To avoid injury from flying debris, wear a face shield or goggles.

14 Turn on the shop vacuum; you should be able to feel suction if you place your hand momentarily over the DOC cleaning cone opening.

 

NOTICE

Regulate air pressure to a maximum of 120 psi to prevent damage to the substrate.

15 Place the air gun nozzle inside the cleaning cone and keep the air gun tip 25 mm (1 in.) away from the DOC to prevent damage to the brick.

16 Start blowing compressed air into the DOC cleaning cone. Move the air nozzle in a circular pattern, starting from the outer edge and work your way inward to center of the DOC. Continue this motion for several minutes.

17 Remove the DOC cleaning cone.

Detroit GHG17 Engine Diesel Oxidation Catalyst Air Cleaning Guide (12)

18 Continue blowing air into the DOC using a slow sweeping motion, making sure to cover 100% of the DOC surface. Keep the air gun tip 25mm (1 in.) away from the DOC to prevent damage to the brick.

19 Move the block-off plate to the outboard DOC and install the cleaning cone onto the inboard DOC.

20 Place the air gun nozzle inside the cleaning cone, keep the air gun tip 25 mm (1 in.) away from the DOC to prevent damage to the brick. Start blowing compressed air into the DOC cleaning cone. Move the air nozzle in a circular pattern, starting from the outer edge and work your way inward to the center of the DOC. Continue this motion for several minutes.

21 Remove the inboard DOC cleaning cone.

22 Continue blowing air into the inboard DOC using a slow sweeping motion making sure to cover 100% of the DOC surface. Keep the air gun tip 25 mm (1 in.) away from the DOC to prevent damage to the brick.

 

23 Disconnect the vacuum and remove the inlet reduction cone and DOC block-off plate.

24 After each DOC has been air cleaned, reinstall both Diesel Particulate Filters (DPF) using new flat band clamps and V-band gaskets.

25 Reinstall the aftertreatment.

26 Run a Parked Regen to verify DOC inlet pressure and check for proper NOx conversion.

How to Use SerDia2010 to Change Low Idle for Deutz EMR3

How to Use SerDia2010 to Change Low Idle for Deutz EMR3 (1)

Here is the illustration show you guide on how to use Deutz SerDia2010 to change low idle parameter for Deutz EMR3.

 

Preparations:

It is provided for using this function, that the engine is operating in min-/max-governor or allspeed-governor mode (f.e. not fixspeed).

How to Use SerDia2010 to Change Low Idle for Deutz EMR3 (1)

SerDia reads out the actual values of idle run and copies them into the labels in the sub array on the left hand side. This values will be saved further, too.
In parallel a tachometer operates on the right hand.
The actual setpoint value and the actual rotating speed are shown,each as a decimal value below the tachometer and also with indicator and hysteresis region.
Button “read data from ECU”:

How to Use SerDia2010 to Change Low Idle for Deutz EMR3 (2)

went back to previous value of idling speed, which was acquired at the start of the UseCase.
Button”store in ECU”:

How to Use SerDia2010 to Change Low Idle for Deutz EMR3 (3)

writes all variables for idle speed back into the ECU.
If the engine is still running, SerDia will offer to stop the engine automatically, so that the programming of the ECU can take place.

text box “new value”:

How to Use SerDia2010 to Change Low Idle for Deutz EMR3 (4)

An input into this text box has to be confirmed by ENTER.
After that, SerDia changes all variables for idle speed and switches over to working
page, so all changes will be activated in realtime.

 

Notice:The input is limited for a speed range of 600 – 1200 1/min.
