DTC P02CC, P02CE, P02D0, P02D2 (K20C1) (2017 2018 2019)
DTC P02CC: No. 1 Cylinder Injector Offset Learning Exceeds Minimum Limit
DTC P02CE: No. 2 Cylinder Injector Offset Learning Exceeds Minimum Limit
DTC P02D0: No. 3 Cylinder Injector Offset Learning Exceeds Minimum Limit
DTC P02D2: No. 4 Cylinder Injector Offset Learning Exceeds Minimum Limit
General Description
The powertrain control module monitors the controlled valve operation (CVO) of each injector. The CVO corrects the injection time of every injector to get a correct fuel quantity. After base adaption is finished in every injection the current injection time variation will be checked against a diagnosis threshold. If the result exceeds a threshold, error counter is incremented. If the error counter exceeds a specified count, the PCM detects a malfunction and stores a DTC.

Malfunction Threshold
The error counter exceeds 100 counts.*
*: The error count is incremented to the counter if the current injection time variation is less than -200 microseconds.
Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
- Injector failure
Confirmation Procedure
Operating Condition
- Start the engine.
- Drive the vehicle for a while with certain loads.
- Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
With the HDS
None.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.
Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
