P2C61 code meaning
Cylinder 8 Fuel Injector B Offset Learning At Max Limit
Powertrain system Generic code P2Cxx codes Check engine light
What P2C61 means
P2C61 closes the series: injector B of cylinder 8 has driven its learned offset into the ceiling, so this valve stays short of fuel despite the longest correction allowed. Because a weak supply pump or low rail pressure would starve every injector of the same set, a Max code on a single cylinder narrows the search to that valve, its wiring or the air path of that cylinder. A lean system B trim on bank 2 (P2BF2) fits the picture on most V8 numbering schemes. Ford's published OBD summaries for the V8 with both injection types omit P2C61, and no other manufacturer documents it; Volvo's bulletin for the Max codes stops at cylinder 4. California's OBD rule (CARB 1968.2, section (e)(6.2.2)) makes an adaptation without remaining range a reportable fault.
P2C61 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2C61
- Check engine light
- Often nothing else noticeable
- Possibly uneven idle or lean misfire on cylinder 8
Common causes of P2C61
- Most likelyVarnish or deposits in injector B of cylinder 8, slow opening
- PossibleCorroded or loose connector, chafed wire or voltage drop at this injector
- PossibleOld adaptation values left at the limit after a repair or software change
- Less likelyAir leak at the intake runner of cylinder 8 (only where the learn uses exhaust oxygen)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2C61 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| C | Area: hybrid propulsion. |
| 61 | The exact fault in that area. |
What to do next
- Note P2C61 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2C61
What does P2C61 mean?
P2C61 means "Cylinder 8 Fuel Injector B Offset Learning At Max Limit". P2C61 closes the series: injector B of cylinder 8 has driven its learned offset into the ceiling, so this valve stays short of fuel despite the longest correction allowed. It is a generic code, so it means the same on every make.
Is it safe to drive with P2C61?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2C61 fail an emissions test?
Yes, it can. P2C61 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2C61 to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P2C61 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
