OBD-II trouble code
P0282: Cylinder 8 Injector Circuit Low
SAE J2012 APR2002: cylinder 8 injector circuit low. On the 6.0L diesel an open coil sets this current direction. On the 2010 M5 the memory line is a short to ground. The printed pair is one injector.

What does P0282 mean?
SAE J2012 APR2002 names P0282 Cylinder 8 Injector Circuit Low. P0283 is cylinder 8 circuit high. The two service documents below use opposite electrical stories, and both name this code. Pick the one that matches the engine.
The 2007 Ford E-350 6.0L diesel FICM diagnostics say the module measures current. Open coils produce low current, which sets the injector circuit low codes. The fault-detection line marks examples with 'ie', from P0261 and P0264 through P0282. The fault-code list names every low code for cylinders 1 through 8, P0279 included, as an open injector circuit or a defective coil. Shorted coils, or a short to ground, produce high current and set the high codes. That 'ie' line runs from P0262 and P0265 through P0283, and the fault list names every high code for cylinders 1 through 8, P0280 included, as a short to ground or a defective coil. The list is the V8. Cylinders 9, 11, and 12 are not on it. On that 6.0L, P0282 is the low-current result, and a short to ground is not the low code. The same page says a failed FICM shows up as a no-start or a constant misfire at all engine temperatures, and that symptoms other than those are not likely the FICM. It also says the FICM is replaced when it did not fail, and that a replacement FICM has no software until it is programmed. FICM logic power below eight volts is a short, an open, or a low battery, checked with the FICM LPWR pid. That pid is filtered and moves in half-volt steps, so a wiggle test is slow to show.
The 2010 BMW M5 (E60) S85 page is 276E - P0282, electrical diagnosis of cylinder 8's fuel injector. The memory line is a short circuit to ground. Terminal 15 on, battery voltage above K_ED_PlusMin. Check the plug and the harness, then the valve, replaced as indicated. The speed limit on that page is 3500 rpm, with power reduction and the MIL after two engine runs. That ground sentence is not the 6.0L open-coil sentence. Do not tell an M5 owner the coil is open because a 6.0L would have stored low current, and do not tell a 6.0L owner the DME saw a short to ground.
A VAG-group list prints 16666 P0282 as injector 8-N865, short circuit to ground, while the next line prints injector 8-N86 for P0283. The component number is not consistent on those two lines. Use the vehicle diagram rather than choosing N865 or N86 from the list.
Common causes
- On the 2007 E-350 6.0L, an open coil, the low current the FICM fault list files as P0282
- On the 2010 M5, a short circuit to ground in cylinder 8's injector driver info, fault 276E
- A short to ground in that M5 injection valve's plug or harness
Symptoms
- P0282 stored
- On the 6.0L page, low injector current from an open coil
- On the 2010 M5 page, speed limited to 3500 rpm and a power reduction
- A no-start or a constant misfire at every temperature, which is the FICM symptom that page names
- FICM LPWR under eight volts
Diagnostic steps
- 1.Identify the engine before choosing a fault direction. 6.0L low current is an open coil. M5 276E is a short to ground.
- 2.On the 6.0L, retrieve powertrain codes from the engine and the transmission side together, which that page says the WDS does in one selection. Do not replace the FICM for one cylinder unless the symptom is a no-start or a constant misfire at all temperatures.
- 3.Check FICM LPWR. Under eight volts: short, open, or low battery, including the logic fuse in the relay center. The pid is half-volt resolution and heavily filtered.
- 4.On the 2010 M5, check the plug and the harness on cylinder 8's injection valve before the valve. The 3500 rpm line is the effect. Do not import the 6.0L open-coil sentence.
- 5.Do not ohm the M5 to a limit the 276E page does not print. Depressurize before a valve is removed. The printed pair is one injector. A FICM is outside it.
- 6.Verify on the 6.0L by the current result that set the code, and on the M5 by 276E not returning with terminal 15 on.
Repair cost
$768 – $953 (one fuel injector replacement, parts and labor, for the 6.0L open coil or the M5 valve after the harness step; a FICM is outside this pair)
RepairPal's national injector replacement, 3 September 2026, is $768–$953 (labor $304–$446, parts $464–$507). The printed pair is that injector, which is the part both of these charts can reach. A FICM was searched as its own parts-and-labor line and is not this pair; the Ford page says that module is replaced when it did not fail. Diagnosis is $125–$183, separate. The 2026 F-150 injector line at $1,130–$1,415 is outside the national pair. RepairPal says the injector job is not a DIY repair.

DIY vs shop
Leave this one to a qualified shop. The barrier here is high-pressure fuel components, where residual pressure remains after shutdown and escaping fuel can penetrate skin. DIY attempts often produce a more expensive problem than the original code.
