Diagnostic Fault Information





Circuit/System Description

The engine control module (ECM) supplies voltage to each fuel injector on the injector high voltage supply circuits. The ECM energizes each fuel injector by grounding the high voltage control circuit of the fuel injector. The ECM monitors the status of the injector high voltage supply circuits and the fuel injector high voltage control circuits. When a fuel injector circuit condition is detected by the ECM, the affected fuel injector(s) is disabled.

Conditions for Running the DTC

* The engine speed is greater than 80 RPM.
* The ignition 1 signal parameter is between 10-18 V.
* The injector has been commanded ON and OFF at least once.
* The DTCs run continuously once the above conditions are met.

Conditions for Setting the DTC

P0201, P0202, P0203, P0204, P0205, or P0206

The ECM detects the injector high voltage supply circuit or the injector high voltage control circuit is open for greater than 4 seconds or for a cumulative of 30 seconds.

P0261, P0264, P0267, P0270, P0273, or P0276

The ECM detects the injector high voltage control circuit is shorted to ground for greater than 4 seconds or for a cumulative of 30 seconds.

P0262, P0265, P0268, P0271, P0274, or P0277

The ECM detects the injector high voltage control circuit is shorted to voltage for greater than 4 seconds or for a cumulative of 30 seconds.

P2146, P2149, P2152, P2155, P216A, or P216D

The ECM detects the injector high voltage supply circuit is shorted to ground or shorted to a voltage for greater than 4 seconds or for a cumulative of 30 seconds.

Action Taken When the DTC Sets

DTCs P0201, P0202, P0203, P0204, P0205, P0206, P0261, P0262, P0264, P0265, P0267, P0268, P0270, P0271, P0273, P0274, P0276, P0277, P2146, P2149, P2152, P2155, P216A, and P216D are Type B DTCs.

Conditions for Clearing the DTC

DTCs P0201, P0202, P0203, P0204, P0205, P0206, P0261, P0262, P0264, P0265, P0267, P0268, P0270, P0271, P0273, P0274, P0276, P0277, P2146, P2149, P2152, P2155, P216A, and P216D are Type B DTCs.

Diagnostic Aids

* The high voltage supply circuits of injectors 2 and 5, and injectors 3 and 6, are paired together with a dual high side driver in the controller. A short to ground, or a short to voltage, on one of the paired circuits will set a DTC for the companion injector. The ECM will also disable the high side driver for the affected injectors.
* The high voltage supply circuits of injectors 1 and 4 are not paired together in the controller.
* Performing the fuel injector coil test may help isolate an intermittent condition. Refer to Fuel Injector Solenoid Coil Test (Fuel Injector Solenoid Coil Test).
* If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan tool Injector Control Circuit Test Status parameters. An Injector Control Circuit Test Status parameter will change from OK or Not Run to Fault if there is a condition with the circuit or a connection.

Circuit/System Verification

1. Ignition ON, observe the DTC information. DTC P062B should not set.

• If DTC P062B failed this ignition, refer to DTC P062B (P062B).

2. Observe the scan tool Current Misfire Counter parameters. The Current Misfire Counters should not increment.
3. Engine operating, observe the appropriate scan tool Injector Control Circuit Test Status parameters. Verify the Injector Control Circuit Test Status parameters display OK or Not Run.
4. Engine operating, observe the DTC information with a scan tool. DTC P0201, P0202, P0203, P0204, P0205, P0206, P0261, P0262, P0264, P0265, P0267, P0268, P0270, P0271, P0273, P0274, P0276, P0277, P2146, P2149, P2152, P2155, P216A, or P216D should not set.
5. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Ignition ON, clear the scan tool DTC information.
2. Ignition OFF, disconnect the appropriate multi-way harness connector X160 or X161, at the rear of the intake manifold.

Note: Testing for steps 3 through 12 is performed on the ECM side of the multi-way harness connector.

3. Connect a test lamp between ground and the high voltage supply circuit terminal of the appropriate injector listed below.

* Fuel Injector 1 terminal 8 X161
* Fuel Injector 2 terminal 2 X160
* Fuel Injector 3 terminal 9 X161
* Fuel Injector 4 terminal 4 X160
* Fuel Injector 5 terminal 10 X161
* Fuel Injector 6 terminal 6 X160

4. Crank or start the engine while observing the test lamp. The test lamp should flash several times and then stop when the DTC sets.

Note: Four of the injector high voltage supply circuits are paired in the controller with a dual driver, refer to Diagnostic Aids.

• If the test lamp is always ON, test the high voltage supply circuit for a short to voltage. If the circuit tests normal, replace the ECM.
• If the test lamp is always OFF, test the high voltage supply circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.

5. Clear the DTC information with a scan tool, then cycle the ignition OFF.
6. Connect a test lamp between B+ and the high voltage control circuit terminal of the appropriate injector listed below.

* Fuel Injector 1 terminal 2 X161
* Fuel Injector 2 terminal 1 X160
* Fuel Injector 3 terminal 3 X161
* Fuel Injector 4 terminal 3 X160

12. Crank or start the engine while observing the test lamp. The test lamp should flash several times and then stop when the DTC sets.

• If the test lamp does not flash, test the high voltage control circuit for an open/high resistance. If the circuit tests normal, replace the ECM.

Note: Testing for the following steps is performed on the fuel injector side of the multi-way harness connector. It may be necessary to remove the intake manifold to isolate the condition.

13. Ignition OFF, measure the resistance between the appropriate high voltage supply circuit and ground. The DMM should display OL ohm.
