11836

What the code means

11836 falls under the ignition category and is rendered as “cylinder misfire.” The engine control unit (DME) registers that combustion of the air-fuel mixture is not happening in one of the cylinders: fuel is delivered, compression is present, but there's no spark.

Severity is moderate. A likely cause is a fault in ignition system components — spark plugs or spark plug wires. According to the source, pinpointing the cause requires diagnostics across all engine components.

Symptoms

• Misfire in a cylinder — that cylinder isn't contributing to engine operation.

The source lists no additional symptoms.

Diagnostics and repair

1. Run diagnostics on all engine components — the code doesn't point to a specific component, so the check has to be comprehensive.
2. Look at ignition system components first: spark plugs and spark plug wires.

The source has no more detailed test procedures, spec values, or part numbers.
