01 // CODE DEFINITION

What P0302 means

P0302 identifies abnormal combustion associated specifically with cylinder 2.

Ignition, injector, compression, intake, wiring, or mechanical problems may be responsible.

02 // COMMON SYMPTOMS

What you may notice

Rough idle
Engine vibration
Hesitation
Reduced power
Flashing check-engine light

03 // COMMON CAUSES

What can trigger P0302?

IGNITION

Spark fault

A plug, coil, wire, or connection may be preventing proper ignition.

FUEL

Injector problem

Cylinder 2 may have insufficient or inconsistent fuel delivery.

MECHANICAL

Compression loss

Valve, ring, gasket, or valvetrain problems may reduce cylinder contribution.

04 // DIAGNOSTIC ORDER

Start here

01

Review cylinder misfire data

Confirm cylinder 2 is consistently accumulating misfire counts.

02

Inspect or swap ignition components

Determine whether the fault follows a plug or coil.

03

Evaluate the injector

Check electrical command and fuel delivery.

04

Test compression

Compare cylinder 2 with the other cylinders.

05 // DIAGNOSTIC PRINCIPLE

Confirm the fault before replacing parts

P0302 identifies a condition detected by the vehicle control system. It does not automatically identify one failed component. Test the affected system before replacing parts.
