P2342

DTC P2342, sometimes indicated as P234200 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the ignition system causing cylinder 7 above knock threshold.

This code is set when the knock sensor in cylinder 7 detects a knocking noise that is above the threshold set by the manufacturer. There are several possible causes for this code, including:
-Damaged or worn piston rings
-Worn or damaged valve seals
-Damaged or worn cylinder head
-Leaking head gasket
-Damaged or worn crankshaft
If this code is set, the best course of action is to have a qualified technician inspect the vehicle and diagnose the exact cause.
