P02CC Code - Cylinder 1 Fuel Injector Offset Learning At Min Limit

Quick Answer

Zero Fuel Calibration (ZFC) is an algorithm used to detect deviations in individual injector performance from nominal. Common causes include Faulty Cylinder 1 Fuel Injector, Cylinder 1 Fuel Injector harness is open or shorted, Cylinder 1 Fuel Injector circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What it means: P02CC indicates Cylinder 1 Fuel Injector Offset Learning At Min Limit.
Common causes: Common causes include Faulty Cylinder 1 Fuel Injector, Cylinder 1 Fuel Injector harness is open or shorted, Cylinder 1 Fuel Injector circuit poor electrical connection.
Severity: High - diagnose this code as soon as possible.

Code P02CC Description

Zero Fuel Calibration (ZFC) is an algorithm used to detect deviations in individual injector performance from nominal. In an overrun/decel fuel shut-off condition, fuel rail pressure is set to 300 bar and small injections are made from a single injector. The observed acceleration in crankshaft speed is detected and compared to the expected acceleration. If the observed acceleration deviates from the expected acceleration by more than 50%, then an additional routine is called adjusts the injection energizing time until observed acceleration matches expected. This information is then used to adjust all pilot injections on that injector to ensure correct fuel delivery. If the absolute energizing time observed for the test injection to yield the expected acceleration exceeds minimum or maximum limits, a code is set.
The Powertrain Control Module (PCM) sets the OBDII code when the observed energizing time for the test injection is 156 us or more lower than the target 430 us energizing time for the given injector.

What are the Possible Causes of the DTC P02CC?

Faulty Cylinder 1 Fuel Injector
Cylinder 1 Fuel Injector harness is open or shorted
Cylinder 1 Fuel Injector circuit poor electrical connection
Faulty Powertrain Control Module (PCM)

How to Fix the DTC P02CC?

Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P02CC code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
