P0263 — Cilindri 1 contribution/Saldo out di range

Q: What does code P0263 mean?

Cylinder 1 contribution/balance out of range. The ECU compares how much work each cylinder does and finds the first one is not pulling its weight. On common rail engines this is the code that leads to injector diagnosis.

Q: Common causes — P0263

Worn injector or delivery out of specification IMA/IQA injector code not updated after a replacement Low compression on that cylinder Leak from the injector return

Q: How do you fix code P0263?

Measure each injector's return and read per-cylinder corrections on the diagnostic tool: together they tell whether the injector needs reconditioning. If an injector was replaced recently, check first that its calibration code was written into the ECU — it is often forgotten.

Severity: Attenzione Can you drive? With caution: limp mode possible, have it checked soon Produttore: Tutti makes (OBD-II standard)

Meaning	The ECU compares how much work each Cilindri does and finds the Prima one is not pulling its Peso. On common rail Motori this is the code that leads a injector diagnosis.
