P0288Cylinder 10 Injector A Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0288 means the control wire of the cylinder 10 injector – the side the engine module switches to ground – is shorted to ground. GM detects this with the driver off: on direct injection at 1 V or less, on port injection and Duramax diesels at 0.5 Ω or less to ground. Ford's 6.7 diesel has its driver chip report the short within 0.3 s. Most systems switch the warning light on in the first trip (some GM port-injection engines and Saab's 2.0 turbo after two) and shut the affected injector off, so the cylinder misfires. Ford petrol engines report all injector circuit faults as P0201 ff instead. Cylinder 10 exists only on ten-cylinder engines; no manufacturer document using this code was found – Ford's V10 uses P0201–P0210 and GM has no V10 – so the description follows CARB and the codes for cylinders 1–8.
- What you may notice
- Check engine light on
- Misfire and rough running, misfire code P0310
- Loss of power, rough idle
- Injector shut off, limp mode possible on diesels
- Likely causes
- LikelyControl wire of the cylinder 10 injector chafed to ground in the harness
- PossibleInjector connector damp or corroded, leakage to ground
- PossibleInjector shorted to its housing internally
- RareOpen control wire (on some GM port-injection drivers this also reads low; P020x sets too)
- RareDriver stage in the engine module faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €50 – €800
