P0305: what does this code mean?
Misfire, cylinder 5
Parts to check, to be confirmed by diagnosis
- Spark plugSearch for my vehicle
- Ignition coilSearch for my vehicle
- Fuel injectorSearch for my vehicle
Good to know: On petrol: swap the coil with that of a neighbouring cylinder; if the misfire follows, it is the coil. A diesel has no spark plug or coil: check that cylinder's injector (return flow, balance) and the compression.
A code points to a circuit or a function, not a part number: confirm by diagnosis before ordering.
