P02D7

Cylinder 6 Fuel Injector A Offset Learning At Max Limit

Q: Is it safe to drive with P02D7?

Short term yes, but cylinder 6's injector correction has reached its limit, meaning that injector is out of spec. Have it diagnosed before running or economy get worse.

Q: Can I just clear P02D7?

It clears, but the learned offset will hit its limit again until the injector or its wiring is repaired.

Fuel injection (injector control) Generic OBD-II High

What it means

P02D7 means the ECM's learned fuel-injector correction (offset) for cylinder 6 has reached its maximum limit — the module is adding as much compensation as it is allowed and cylinder 6 still isn't delivering fuel as expected. It usually points to a worn or out-of-spec injector, its wiring, or a fuel-delivery issue on that cylinder. The engine runs, but the pinned correction should be diagnosed and reset.

High

Can I keep driving? Usually drivable — the engine runs, but cylinder 6's injector correction has maxed out, so expect uneven running that should be diagnosed before it worsens.

Common symptoms

What you'll notice

Check-engine light on
Rough or uneven idle
Possible cylinder 6 misfire, hesitation, or reduced power
Sometimes no obvious driving symptom beyond the light

Common causes

Most likely first

Worn or out-of-spec cylinder 6 injector needing more correction than allowedLikely
Damaged, corroded, or loose wiring/connector at the cylinder 6 injectorCommon
Fuel-delivery issue to cylinder 6 (pressure or flow) skewing the learned offsetCommon
Faulty injector control module or ECM — least commonLess often

How to diagnose & fix

Work through it in order

Read freeze-frame data and review cylinder 6's injector offset/correction values with a scan tool.
Inspect the cylinder 6 injector connector, wiring, and injector-control-module supply/ground circuits.
Test the injector and verify fuel pressure/flow; compare cylinder 6 to the other cylinders.
Replace the injector if worn or out of spec, then reset injector learning. Clear and re-test.
