Code status

Needs verification

Not yet verified against SAE J2012_202509 / J2012DA. Treat unverified rows as a lookup aid, not repair authority.

System: Injector

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not replace cylinder 8 parts blindly; wiring, connector, or driver-control issues can create the same code.

Useful checks before replacing parts

Check cylinder 8 injector connector fit, power feed, control circuit, harness routing, and terminal tension.
Compare injector resistance, current ramp, or balance data with other cylinders when service information supports it.
Use misfire counters and fuel-trim data to separate injector circuit failure from fuel pressure or mechanical faults.
