Circuit/System Description

The engine control module (ECM) has the ability to learn injector timing performance. With the engine at operating temperature and in closed throttle decel mode, the ECM will pulse each injector individually and measure the changes in rotational speed of the crankshaft using the input from the crankshaft position sensor (CPS). The ECM will run this diagnostic at one fuel rail pressure operating point for each injector. The ECM stores the injector timing value.

Conditions for Running the DTC

* Ambient air temperature is above -7° C (19° F).

* Fuel temperature is between 0-80° C (32-176° F).

* Engine temperature is greater the 50° C (122° F).

* Battery voltages is greater than 10 V.

* Diesel Particulate Filter (DPF) Regeneration is not active.

* Fuel system status is in fuel shut off mode during decel.

* Engine speed is between 950-1850 RPM.

* Accelerator pedal position is less than.05 percent.

* Vehicle speed greater than 0 mph.

* Ambient pressure is above 75 kPa.

* No other DTCs are present.

* The DTC runs once per trip when the above conditions exist.

Conditions for Setting the DTC

A fault is detected when the corrected energizing time falls outside a calibrated threshold for greater than.01 seconds.

Action Taken When the DTC Sets

DTCs P01CC, P01CE, P01D0, P01D2, P01D4, P01D6, P01D8, P01DA, P01CB, P01CD, P01CF, P01D1, P01D3, P01D5, P01D7, or P01D9 are Type B DTCs.

Conditions for Clearing the DTC

DTCs P01CC, P01CE, P01D0, P01D2, P01D4, P01D6, P01D8, P01DA, P01CB, P01CD, P01CF, P01D1, P01D3, P01D5, P01D7, or P01D9 are Type B DTCs.

Diagnostic Aids

* This Diagnostic parameter is stored in the ECM over a period of time. Time to set this DTC may take several drive cycles.

* Contaminated or improper fuel quality may cause this DTC to set.

* Worn base engine components or differences in cylinder compression may cause this DTC to set

Circuit/System Verification

1. Verify the proper fuel is used. Refer to Fuel System Specifications [1][2]Fuel Delivery and Air Induction and Contaminants-in-Fuel Diagnosis Contaminants-in-Fuel Diagnosis.

2. Verify there are no aftermarket performance enhancing devices installed on the vehicle.

3. Perform the Fuel Injector Correction Reset for the appropriate fuel injector. Refer to Fuel Injector Correction Reset Fuel Injector Correction Reset.

4. Perform the Crankshaft Position Reluctor Wheel Learn. Refer to Crankshaft Position Reluctor Wheel Learn Testing and Inspection.

5. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. Refer to Fuel Injector Timing Learn Fuel Injector Timing Learn.

• If DTC resets
Refer to Circuit/System Testing.

• If DTC does not reset

6. All OK.

Circuit/System Testing

1. Perform a engine compression test. Refer to Engine Compression Test Testing and Inspection.

• If engine compression is not within specification
Repair as necessary.

• If engine compression is within specification

2. Replace the appropriate Q17 fuel injector.
