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.

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.

Detroit Diesel GHG17 Heavy Duty Mechanical Cylinder Compression Test

This instruction show you guide on how to perform mechanical cylinder compression test for Detroit Diesel GHG17 heavy duty.

Related Contents

DDDL 8.20 2024

Nexiq USB Link 3 Adapter

Note : This test should be performed only if directed here by a diagnostic procedure.

Perform the following steps for a mechanical compression test on a GHG17Heavy Duty DD Platform Engine:

Jake Brake ® /piston

Valve lash/valve train damage

Camshaft timing

Cylinder liner/ring damage

Fuel injector hold-downs

Blown cylinder head gasket

Cracked cylinder liner or cylinder head

Valve or seat damage

Note : First perform the Relative Cylinder Compression Test using DiagnosticLink.. If results indicate a weak cylinder, perform this mechanical compression test.

1 The valve lash needs to be checked before the mechanical compression test is performed.and adjust as necessary, if no adjustment is needed continue to step 2.

2 Run the engine and bring the engine coolant temperature to normal operating range, 88 to 96°C (190 to 205°F).

3 Disconnect the batteries and plug the batteries into a battery charger. Refer to OEM procedures.

4 Remove rocker cover.

5 Remove the fuel injector harness.

6 Disconnect electrical contacts at the fuel injectors.

7 Disconnect the two wiring terminals going to the Jake Brake ® solenoids.

8 Disconnect the 14-pin fuel injector harness connector.

9 Remove the spring clip holding the fuel injector harness connectors to camshaft frame.

10 Remove the fuel injector wiring harness(es).

11 Remove the high pressure fuel line from all cylinders.

12 Remove all fuel injectors.

13 Remove excess fuel from cylinders using a vacuum pump.

14 Install the compression test adapter (J-47411) into the fuel injector bore in the cylinder head.

15 Install the fuel injector hold-down clamp and bolt. Torque the bolt to 20 N·m (14 lb·ft) + 90 degrees.

16 Install the fuel rail plug (J-48704 or W470589129100).

17 Install a hold-down bolt onto the Jake-Brake ® solenoid and snug the bolt.

18 Reconnect the batteries; keep the battery charger plugged into the batteries.

Note : Verify that the battery voltage does not go low enough to affect engine cranking speed. If the cranking speed is affected, then the results will be inaccurate. A battery charger will help to maintain an acceptable battery voltage.

19 Using DiagnosticLink start the Mechanical Compression Test routine, this will disable fuel from the Quantity Control Valve.

20 With the batteries fully charged, crank the engine over five compression strokes at 150 rpm or greater using the starter motor. Record the compression reading on the gauge.

21 At normal operating temperature, the compression reading should be no less than 28 bar (400 psi). If compression readings are below specifications, repeat step 13 with a different gauge to be certain of the reading.

Note : Fuel injector hold-down bolts are a one-time use item.

22 Remove the fuel injector hold-down clamps. Discard the hold-down bolt and remove the compression test adaptors.

23 Repeat steps for all suspect cylinders.

24 Repair engine as necessary.
