P0288 indicates a low injector circuit on cylinder 10. The injector 10 control path is grounded, missing voltage, or below expected current.

Code status

Needs verification

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

System: Injector
Scope: iso-sae-controlled-p0

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 injector 10 before tracing the low circuit through wiring and controller driver control.

Useful checks before replacing parts

Measure injector 10 feed voltage, control command, resistance, and current while checking for short-to-ground faults.
Compare cylinder 10 misfire counters, contribution, injector pulse, fuel trims, and freeze-frame load or temperature data.
Inspect injector 10 connector terminals, harness routing, shared injector feed, moisture, oil intrusion, and rubbed insulation.
