Detroit GHG17 Heavy Duty Crankcase Pressure Test Guide

1 Start the engine.

2 Run the engine and bring the engine coolant temperature to normal operating range, 88º to 96°C (19º to 205°F).

3 Install the crankcase pressure test adapter (W651589029100) on to the oil fill opening. Attach a water manometer, calibrated to read pressure as inches of H2O, on to the adaptor.

4 Run the vehicle to full load and rated speed with a loaded trailer or dyno.

5 Measure and record crankcase pressure.

6 Shut down the engine.

7 Remove the adaptor from the oil fill opening.

Note : Any tubing used to feed the manometer will artificially increase the crankcase pressure results.

8 The correct crankcase pressure should be less than 5 inches of H2O at full load. If the engine crankcase pressure is greater than 5 in. H2O

How to Replace TMAP Sensor for Kohler ECH440 EFI System

How to replace Temperature/Manifold absolute pressure (TMAP) sensor for Kohler ECH440 EFI System.

2024 Kohler Kira Integrated Remote Analytics 2.6.0.0

KOHLER EFI Diagnostic 2.11.0013

A sealed non-serviceable integrated sensor that checks both intake air temperature and manifold absolute pressure. Complete replacement is required if it is faulty.

Sensor and wiring harness can be checked as follows.
If a fault code indicates a problem with Intake Air Temperature (TMAP) Sensor Circuit (P0112 or P0113), it can be tested as follows:
1 Remove TMAP sensor from throttle body.
2 Allow it to reach room temperature (20°C, 68°F).
3 Unplug Black connector from ECU.
4 With sensor still connected, check temperature sensor circuit resistance between Black pin 10 and 8 pin terminals. Value should be 1850-2450 Ω.
5 Unplug sensor from wire harness and check sensor resistance separately across pin. Resistance value should again be 1850-2450 Ω.
a If resistance is out of specifi cations, check local temperature. Sensor resistance will go down as
temperature is higher. Replace TMAP sensor if determined to be faulty.
b If it is within specifi cations, proceed to Step 6.

6 Check circuits (input, ground), from main harness connector to sensor plug for continuity, damage, etc.
Connect one ohmmeter lead to Black pin 8 in main harness connector (as in step 4). Connect other lead to terminal #3 in sensor plug. Continuity should be indicated. Repeat test between Black pin 10 and terminal #4 in sensor plug.
7 Reinstall sensor.

If a fault code indicates a problem with Manifold Absolute Pressure (TMAP) Sensor Circuit (P0107 or P0108), it can be tested as follows:
1 Make sure all connections are making proper contact and are free of dirt and debris. Slide locking
tab out and pull off TMAP connector. Turn key switch to ON and check with a volt meter by contacting red lead to pin 1 and black lead to pin 2. There should be 5 volts present, indicating ECU and wiring harness are functioning.

2 Check continuity in wire harness. Ohms between Pin 3 at sensor connector and Black pin 11 connector at ECU should be near zero ohms. If no continuity is measured or very high resistance, replace wire harness.

3 Check to make sure throttle body is not loose and TMAP sensor is not loose. Loose parts would allow a vacuum leak, making TMAP sensor report misleading information to ECU.
a Tighten all hardware and perform an ECU Reset and a TPS Learn Procedure to see if MIL will
display a fault with sensor again. If MIL finds a fault with TMAP sensor, replace it.

CLAAS CDS 7.5 Diagnostic System 2021.05

Procedures:

Repairing the cylinder block

Checks and measurements of the liners

Check the internal diameter of the cylinders for runout, tapering and wear, using a gauge (2) with a dial gauge (1), set to zero on the ring gauge (3) with a diameter of 117 mm.

NB: If you do not have a ring gauge with a diameter of 117 mm available, use a micrometer.

Measurements must be taken for each cylinder at three heights along the liner and on two perpendicular levels “A” and “B”.

Replace the cylinder if the maximum wear differs by 0.150 mm or the maximum runout by 0.100 mm from the values indicated.

Do not attempt to correct or deglaze.

NB: The cylinders are provided as spares with selection class “A”.

Caterpillar C9 Engine 15 164-2 Injection Actuation Pressure Signal Erratic

The Engine Control Module(ECM) detects the following conditions:

The injection actuation pressure is greater than 3 MPa (435 psi) for more than three seconds when the engine is off.

The difference in the actual pressure and the desired pressure is greater than 2 MPa (290 psi) for more than ten seconds with the engine running.

Actual rail pressure is between 11.0 MPa (1595.41 psi) and 17.4 MPa (2523.66 psi) for more than ten seconds.

Sensor current changes more than0.075 Amp and rail pressure changes less than 0.5 MPa (72.5 psi) with the engine on.

The engine is not running and the ECM has been powered for at least four seconds.

Cold mode is not active.

Engine speed is 0 rpm for more than 3 seconds and the engine is not running.

The injection actuation pressure sensor measures the pressure of the oil in the high pressure oil manifold. The high pressure oil in the manifold is used to actuate the injectors and the high pressure oil is used to control the fuel injection pressure. Fuel injection pressure is based on inputs from the sensors. The inputs are used by the Engine Control Module (ECM) for calculating the fuel injection pressure. The ECM uses the reading from the injection actuation pressure sensor in order to control the operation of the injection actuation pressure control valve.

Allison 3000 & 4000 Gen5 Turbine Shaft Speed Sensor Circuit P0715 Solution

This instruction show you steps on how to solve Allison 3000 & 4000 Gen5 transmission turbine shaft speed sensor circuit P0715.

Related Contents:

Allison DOC GEN5 Diagnostic Software 2024.07

2023 Diesel Repair Desktop DTC Solutions V2.9.98+ Diesel Explorer

DIAGNOSTIC RESPONSE:

DNS, Lock in current range

CIRCUIT DESCRIPTION:

The speed sensors are devices which convert mechanical motion to an electrical signal. This test detects a turbine speed sensor circuit short to battery, ground, or open.

ACTION TAKEN WHEN THE DTC SETS:

When DTC P0715 is active, the following conditions occur:

1 If the DTC sets while shift not in process, remains in current range.

2 If the DTC sets while shift is in process, complete shift and lock in that range.

3 There is no response to shift selector requests.

4 DTC is stored in TCM history.

5 The CHECK TRANS light illuminates.

6 The TCM inhibits TCC engagement.

7 The TCM freezes shift adapts.

CONDITIONS FOR CLEARING THE DTC:

Use the diagnostic tool to clear the DTC from the TCM history.The TCM automatically clears the DTC from the TCM history if the vehicle completes 40 warm-up cycles without the DTC recurring.

DIAGNOSTIC AIDS:

DTC P0715 may be caused by:

1 W120 and/or W180 shorted to another wire in chassis harness or to ground.

2 W120 and/or W180 high resistance or open circuit.

3 Broken or defective connector assemblies allowing pushed back pins to short together.

4 Unlocked connectors, missing seal plugs allowing moisture in connectors.

5 Fatigued wires at speed sensor connectors (broken strands).

6 Incorrect pin crimps or expanded terminals.

7 Defective turbine shaft speed sensor.

8Defective TCM.

9 Damaged rotating clutch drum.

10 Wire pair not twisted or not sufficiently twisted.

NOTE:Confirm that the speed sensor wiring consists of twisted pairs at the rate of 12 to 16 twists per 300 mm. These twists must extend the entire length of the wiring harness to within at least 50 mm of the speed sensor connector.

NOTE: The OEM Transmission warranty, or the extended coverage for parts and labor, does not cover transmission or vehicle damage caused by drivelines that do not meet the OEM Transmission specifications.
