P02D6

Cylinder 6 Fuel Injector A Offset Learning At Min Limit

Q: Is it safe to drive with P02D6?

Usually yes for short trips, but the injector's fueling is no longer accurate on cylinder 6, so have it checked to avoid rough running or misfires.

Q: Can I just clear P02D6?

It will return until the injector calibration or its wiring is corrected — some injectors also need their trim code re-entered after service.

What it means

P02D6 means the engine controller's fine-tuning of the cylinder 6 injector — the small offset it learns to keep fueling accurate — has reached its minimum limit and can't correct any further. That usually points to an injector that's drifted out of calibration, or a wiring/control-module issue affecting its signal. Cylinder 6 may run slightly rough until the injector or circuit is corrected.

High

Can I keep driving? You can usually drive, but cylinder 6 may run rough as its injector calibration drifts. Have it checked soon to keep fueling accurate.

Common symptoms

What you'll notice

Check-engine light on
Rough idle or a slight miss from one cylinder
Minor hesitation or reduced smoothness
Often no dramatic driving change beyond the warning light

Common causes

Most likely first

Fuel injector on cylinder 6 out of its expected calibration rangeLikely
Damaged wiring or a poor connection at the injector control moduleCommon
Corroded or loose connector affecting the injector signalCommon
Faulty fuel injector control module or its supply/groundLess often

How to diagnose & fix

Work through it in order

Read freeze-frame data and confirm the offset-learning fault is on cylinder 6.
Inspect the injector and control-module wiring and connectors for damage or corrosion.
Check the injector control module's supply voltage and ground circuits against the battery.
Verify the cylinder 6 injector's calibration/flow; replace it or re-enter its trim code if required.
If the circuit and injector are good, evaluate the control module. Clear and re-test.
