DTC P268A or P2696 (LPL or LPV)
Diagnostic Instructions
DTC Descriptors
| DTC P268A: Fuel Injector Calibration Not
Programmed |
| DTC P2696: Injector Calibration Incorrect |
Circuit/System Description
The control functions for the fuel injection system are
integrated in the engine control module (ECM). During the
manufacturing process, each injector flow rate is measured and
recorded as injection quantity adjustment flow rate data. This
data, together with the injectors cylinder position, is stored in
the ECM. When the ignition is turned ON, the ECM monitors the fuel
injection flow rate numbers to ensure they are present.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
The fuel injector injection quantity adjustment flow rate data
is not programmed.
Action Taken When the DTC Sets
DTCs P268A and P2696 are Type B DTCs.
Conditions for Clearing the DTC
DTCs P268A and P2696 are Type B DTCs.
Diagnostic Aids
Verify that the ECM has the correct part number for the
application.
